tbi throttle position sensor adjustment

{ FSM is Factory Service Manual } One guy mis-indexed the TPS prongs to the matching prongs in the TB, and he got Unflood mode. operating temperature and then adjust the throttle stop screw in or out until (8v example) I am not a body man. MPI is 16v Multipoint Injection motors, and has no Dash pot steps, or device. NOTE 1Exceptions: G16a TBI EFI 1989/90 ONLY using these special steps only. If youve selected the correct COM Port, youll see data scrolling when the key is in the on position and when the engine is running. 91 GMC C3500 454 350 TBI TPS Idle Adjustment mossman381 52.7K subscribers Subscribe 66K views 5 years ago Checking and adjusting the TPS (throttle position sensor) on the 91 GMC C3500. 0v means idle, 5v means not idle. (over range, on the meter , means Infinity , and that is what causes, DTC-44 flash code errors, at idle. (however an analog meter may see them or a graphic GMM may, and all scope for sure can). Tighten the screw by turning it clockwise. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. The sensor detects the opening and closing of the throttle valve and feeds that info to the vehicle's computer. To start with, turn the key to the on position and then find Go EFI Tuning on the main menu and press enter. 1 Throttle Angle Pot. Any one of the above issues can cause a an IAC fault code to set in the ECM. : (off car tests) (will cause , engine that loves to flood ,cranked cold) but does make calibration easy, sure (1/2 joking). Works well. Engines that have higher compression or are new/rebuilt can have higher If the ECU Pin A14 blue-white wire grounds, to the body of the car , the car is DANGEROUS ! 1986-1982 2.5L (R) 151" 17068996, 17078274 TBI 14050 Skyhawk 1982 1.8L (G) 110" 17067587, 17068612, 17078516 R-2 CARB 14053 All conn. have lever locks, and Suzuki dont sell connectors. Push the multimeter pin into the TPS screw and check the voltage. Also, the IDLE switch part is not a real gold zero ohm switch , it too is carbon, reading about300 or 500 ohms. The TPS was calibrated with the DP active. ( except some 1.3L Carb. This photo clearly shows the 2 devices inside, the unit. FSM TBI actual pages on calibration. Nothing more. I've got an '89 and used a scanner to find out my TPS was shot. What matters are the steps. If it stays closed too long, the ECU will fight you, as you tip in the throttle , one of the most odd sensations in car, you will ever experience, here) might be able to bend the gold tab a bit, usually on the adjustable tps you loosen the two screws holding it on and twist the unit then tighten the screws. (the TV is the Throttle valve.) Setting the throttle stop screw can be to discuss your individual requirements, final costs and delivery interval. Ohms. This will allow you attach the leads of your Volt Meter to the various pins for testing. Aftermarket camshafts with lots of duration or lots of overlap tend to lower the (if the auto ranger shows 2.01 K that means near 2000 ohms, K means times 1000. (some cars not this, one use real switches and many Technicians, know how those works, and my comment) TCM, transmission controller module (4 speed automatic) You've adjusted the Throttle Plates using the idle stop. The Advance must be smooth. Seechart on top of this page. If idle speed is not okay after cycling system, problem is usually caused by a dirty throttle plate or vacuum leaks. Very bad that. plug It is located on the left front corner of the TBI body, just ahead of the throttle arm. less than 500 ohm and infinity. The 16v uses software for a Dashpot function. Location. If the TPS errors are bad enough (with DTCs to match) and constant, the ECU may go, tolimphomemode and car does start. Put back to stock and sold. 1: The end to end ohms on your POT must be steady at all times. end on car tests. If your Chevy Equinox has a bad throttle body, it can cause it to run terribly. the Throttle Position Sensor, which we discussed in my Jan/Feb 2008 segment. Adjust the TBI. This fuel then makes its way through the system and could . NOTE: On (A/T) models, connector terminals are identified by (for sure ,300 to 500 range works ) (use a 6v, 9v or 12vdc battery as your supply , or a 5v power supply , really 3 to 12vdc works. ) Where is the "throttle adjusting screw" ? Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped. DO not open the TPS like I DID Below !, this is a destructive examination ! METER MADNESS: Throttle Stop Screw (called a load) To adjust the throttle position sensor (TPS) of the Vehicles you must remove the Vehicles and alter its makeup slightly. Never hot wire injectors or VSV solenoid valves with ECU hooked up.. or Boom you let the smoke out !, TPS FAILS:(TPS , its wires. Pin 4 +5vdc from ECU. 92-98 on the engine (such as what would occur if the automatic transmission was The Dash pot is on the lower left, clearly seen. Insert a safety pin into the 3G connector on the voltmeter, sliding it between the rubber seal and the electric wire. The Dash Display TPS reading is almost Zero and the voltage reading has moved into the 0.50 volt range. Plug in the scan tool to the ECM. I then drop the DASH pot, arm and the throttle opens and the PIN C goes to near 5 volts, (closed switch ) Side1 is the calibration pin. Common symptoms of a bad throttle body include, dirt and grime, the check engine light, and an erratic idle. In side the TB , Throttle body is a Throttle Valve, TV. If these ck ok there are other more complicated issues you would need a scan tool to ck. With the ignition still on, Begin the calibration. FYI: Make sure your DMM meter is working ok , first. Turn ignition switch is "OFF' wait at least 10 seconds. Other pins open will throw over voltage DTCs for TPS. and CAL means you get the switch to just close, and you stop turning the TPS body. throttle bore. TBI Adapters; Throttle Position Sensor; . See calibration for more details. To help us guarantee the correct parts for your classic car. well, one is ground , one is 5v, and TP is low volts) Its the gray wire, with no stripe.). All colors are harness colors. Flow rates are determined primarily by the AIR meter(MPI) or MAP(TBI) , the ECU sees air flow into the engine and matches measured AIR, with proper injections. Attach the positive (red) wire of the voltmeter to the safety pin and turn on the ignition switch without cranking the engine. An electronics guy, calls this the wiper pin, that is because it wipes the carbon, as it moves and picks off a new resistance, as it moves. Pin B stuck at 5v, is caused by a bad TPS or the ground wire broken. There are many features and function in the ECU that trigger off this TPS switch, most or all will malfunction. are you using the stock TPS? and Fast idle commands(ECU) will never happen. NOGO= Open Switch. Omg what is a Carb? So there are 2 tests and only 1 calibration. These simple tests follow below: TheDash Pot must be retracted, when stated. This may be .045-.065 volts. (all ways) The TP pin pin can do that (DTC #22) and is a bad TPS. (the ECU does not use this way, but I check it so I can find glitches not found , B to D.) Now that youve installed the TPS following the directions posted elsewhere on the site, its time to adjust the TPS for optimal performance using either WinALDL software or a Digital Voltage Meter as shown below. "Check . Back probe the TPS connector, using theneedleson the red meter test lead. (non 89-91) See how to fix the folly of finding that the TV valve is not 100% closed and some one messed with that screw above. (and patience galore) Scope on pin B . fast. ON means the switch is closed (very low ohms ,Typical. 1991+, Graphic 1: You can do on car voltage tests, or simple ohms (resistance )test. Too late TPS idle switch opening. Lock down the TPS side screws. We now test the TPSswitch PIN. The TV must not bepacked in GUNK causing TV to not fully close. NO MPI engine G16B has such a device. If there is no signal or a TPS signal way out of parameters .. the PCM will set a trouble code. None of the 3 throttle cables: 1-driver, 2-A/T kick down or 3-Cruise cables, interfering with the throttle valve. This occurs because the ISC idle servo action was not canceled, at throttle tip-in. I set the bore/TV gap (if monkeyed)(see my crude solutions here) Those nincompoops? 2. pin on the TPS, or you MAYblow upthe 8v ECU copper circuit trace, 16v is better protected. When you start any TBI car, the Dash Pot must retract before 30 seconds expires or that part is bad. ( it shows what your right foot is doing, only) Lock down those TPS side screws. This was. Make sure that accelerator pedal is fully released: 2. (timing jumps during static timing procedures?) This means there isnt as much pressure difference to force air into the Meter to B and D ,(throttle angle) ohms varies from about 1k to 5k ohms (this angle and resistance, is crude!, but it only needs to vary and not glitch. They utilize a MAP sensor, coolant sensor, knock sensor, and other TBI controls appropriate for the model year of the engine. The IAC valve cannot be tested using conventional The primary purpose a throttle position sensor (TPS) is to give information to the car's computer about the throttle. STOICH: (means perfect fueling) that happens in Closed Loop mode of the ECU. Wrong engine in car, wrong ECU, wrong, THROTTLE BODY, some joker put the wrong generation parts on top of engine? No dash pot. For sure BENCH setting is super easy, and works best do to , you see carbon blockage at TV/ Bore , and fix that. they are set loose per the FSM. Yes, setting up 94 thou , is a pain, no feeler gage set has this size. If this pin fails, for any reason, TV cables (up to 3 cables) not set at10mm play, or TV boreblocked in carbon,these faults must be cleared first or theCalibration steps will all be wrong. Adjust the idle stop screw The engine is.030 over with a EFI cam and 9.5:1 compression with aluminum 63cc heads. Photo 5, do not attempt to do this. Place the TBI assembly in a suitable holding fixture to prevent damage to the throttle plate and injector electrical . A set of feeler gauges. to be opened up to compensate. The original tps costs too much. Loosen the jam nut and unscrew the throttle stop screw all the way so that the throttle blade closes fully against the throttle body itself. The TPS should read between 4.0 and 5.5 volts. Key off: MPI, the 16valve engine with the words 16 valves embossed on top of valve cover, and is multipoint INJECTED (4 injectors). TPS end Connectorunplugged, do not force it. CUTFUEL cranking. about 50 ohms or near 0volts) OFF means the switch reads, Infinity. The 8V factory TPS data pages: see? You can even do so with a scope to see if the TPS glitches, It can be near tested 100% with proper tools. Turn ON the ignition, but do Never touch this screw below, the feeler is the Calibration tool . This is caused by worn carbon on the above rings, end of life. The 89/90 applies but the stop screw has special rules and steps for calibration and idle speeds. I check that C to D is equal to or below 300 ohms throttle closed (if not it needs calibration) (G16A TBIDash potIS FULLY retracted) if infinity its out of calibration, if 300 or below its OK. It may accelerate smoothly, but lack power. The POT side TP SIDE: and kick down cables. Factory TPS calibration procedure for the 16valve MPI 92-98 Sidekick or Trackers. Never ground out the +5vcd refr. this car runs like a rape date-will burn first and second easy and its an automatic. TPpin is the Throttle angle pin (wiper) of the TPS, not the idle switch. installed the TPS following the directions posted elsewhere on the site. If the idle switch fails, the ECU will not allow idle speed controls. Resetting the throttle body on a Honda is very simple. NOTE: Whenever you adjust your carb idle via the idle adjustment screws, you need to check the TPS settings. ECM or PCM) Push the multimeter pin into the TPS screw and check the voltage. connected, ground the diagnostic (ALDL) terminal (same as you would do to flash This short video covers the instillation and calibration of a new TPS unit. this gap and that is what I use for guide lines getting this correct. Please send photos, relevant images associated to your classic car parts order. Icle > IAC Startup > IAC Park Position Using the software - Idle ICF (tachometer icon) > IAC Parked Selection BEGIN TESTING the G16A, TBI engine 1991- 1995: (8 valve , engine only) The 3 video tests (mp4) Seegraphic1: (a bad indication is the falling (negative ) spikes, called glitches. 4. The green arrow is pointing to the voltage reading which should be close to 0.50 volts. (DIZZY). Sorry I didn't have enough time earlier to post up all the details. (Accelerating he/she is?) < with good skills you can set it with one feeler(calib). Loosen the top bolt on the TPS sensor a couple turns with the socket wrench. Myths: SFYAUTO CPS Crankshaft Position Sensor 12596851 5S1695 Compatible With GMC Pickup Chevy Silverado Suburban C1500 K1500 K2500 K3500 G30 P30 Cadillac . ALive on car TPS voltage test: TBI only. Hi! Disconnect the negative battery cable and set it aside. ignition in the off position, replace the fuel pump fuse. (thus real, and no errors set) (mine varies from 1 to 4v with right foot action or hand turned TV valve. This method guarantees some tiny fractions of inches ( of over/under-travel.) The TV can have up to 3 cables and each must be adjusted to factory spec. It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. This is why the feeler gauges are used. (the glitching can be VERY fast, 20/1000s of second ) Once the fans come on, let the car sit idle with all accessories disabled. New wiring harness extension assembly to extend the throttle position sensor wiring for the listed applications. is adjusted incorrectly (throttle resting closed too much), There is a mechanical The ECU sees VOLTS on this pin, and watches forfast changes to the voltageand never (cept cranking) uses the exact voltage to do anything. on the engine (such as what would occur if the automatic transmission was Start engine and warm up sufficiently. And cut fuel mode. This TBI 8valve device (back side of Throttle body) must be retracted someway to do the TPS calibration. As noted above, Do not over tighten the driver nut. Test 4: (the idle switch tests, after getting DTC 44 and 45?, (stuck low, or stuck high , respectively) Note now that the main resistor A to D is very crude, its not precision at all, so if yours reds 4000 ohms and steady , then that is what it is. even when your driving and just cruisin like 30 mph . or open 5v wire (like 5vdc is dead on the 5v pin of TPS, 5vdc gone is bad ECU ) Volt meter, Ohm meter (resistance) orDMM. but at with the pedal to the floor, it only goes to 3.9v (the old sensor did this too, probably didnt need replaced.) Bucking or misfiring (rich) The TPS on this car is tricky to calibrate (16v). (the reading of 4.0K is 4000 ohms.) Tighten all TPS screws (a double check) and put back its connector. Test the voltage of your TBI using a multimeter. Turn the key ON but don't crank or start the engine. The ECM resets the IAC valve when the car is repeat them all. You control the throttle body position with the . oops wrong TBI there for your ECU. It senses the air, heat, and light, and sends the information to the ECM which adjusts the throttle and fuel supply accordingly. I have the only list like this in the web. DTC errors, 31, 32 ,33 or 34, or starting in 1996 DTC errors P0101, 102,or 103 (These errors trip failsafe), DIY: crude way, ( super easy, super cheap , fast? if the Auto ranger shows 0.300 kthat is 300 ohms. It will never read zero ohms ever, like real gold contact switches would. The minimum air setting is what is used to describe the amount of air Idle Air Volume Learning (Throttle Position Learning) Again, this side (angle) , is never calibrated. ), Side issue? J18 idle speeds out of control are covered here. If unable to pull 6", be sure front TBI throttle stop screw is not limiting throttle travel. When working correctly it used to read 0.65v at idle and the "new" one which replaced it reads about 0.56-0.58. (or have dead spots as you turn the throttle shaft). provided earlier. You are done. air will always be allowed to enter the engine around the throttle valve. CCW= counter clock wise , CW , guess? steady it must be. engine around the throttle blade or thru the IAC passage at idle. Its no different than on car tests, with connector pulled off, and again the DASH POT must beretracted on the G16 TBI body. Keyon, NOT RUNNING test: These errors can also cause the sparktiming freeze jumperto fail, and timing jumps, when frozen by you and your jumper wire. +1 flashing? Below is Throttle body shown up side down, setting the TPS the easy way, its near impossible to set on car, with the above bracket in place. Unfasten the hose from the pressure sensor and remove the bottom bolt of the TPS sensor with a socket wrench. FYI: CW = clock wise. This function has the same parallel to the high speed Accelerator pump device inside many carburettors. The ECU uses this signal to adjust the fuel injectors and ignition timing. Turn the stop screw back in until it just touches the linkage, then turn in turn more. Test the voltage of your TBI using a multimeter. (off topic ) Connect a battery of any kind, to from pin A do D. (pin A is plus pin) (using any cheap 9v smoke detector battery works) Consult the engine diagram that came with your vehicle for extra guidance. ONE FEELER setting on older kicks. *(8 inches HG vacuum dose it) at nipple seen below. Remove the air cleaner lid and the air duct leading to the throttle body using the Phillips screwdriver. Turning the TPS down may help improve the way your Vehicles runs, but if you turn it too low, your Vehicles may not start. These settings adjust how much fuel, at varying . Pin B must not be stuck at 0v. There are This helps the ECM learn the position of the IAC valve. this would result in it getting wedged/stuck closed in the throttle bore), some The voltage tracks my foot throttle 1:1 that is direct action and linear) The engine has huge induction air leaks , making the TPS ECU monitor software report false TPS errors. FAILURE SYMPTOMS Hesitation, tip in surge, engine pinging, no torque converter lockup. Remove it and check it. The throttle position sensor (TPS) is a device on the engine that detects the position of the throttle plate. if not the ground is bad.

The ECU will not set a code for Glitches. valve) closes this DP device (vacuum sent) after say 3 to 15seconds after a start) If not fix this first. The pot side of this TPpin 1(bottom) andpin 3, varies from very low ohms (typ. TESTING the 16V TPS. It comes from the factory with a protective metal cap over it. The throttle position sensor is mounted to the throttle body on top of the engine. You control the throttle body position with the . (<< Engine > Sensors > TPS testing and calibration, all Sidekicks and Trackers. TV= throttle valve, that is the butterfly valve, dead center inside theTB,the Throttle body. (minimum air setting). Sides: 2. JavaScript is disabled. The easiest way to adjust the Throttle Position Sensor (TPS) is to use the shareware program WinALDL. Because the throttle valve cannot be allowed to completely close (because (This cut wire,etc) : any of 3 throttle cables set tight, TV,cruise and A/T kick down cables (set wrong) The spec. (hand vacuum tool, tie it back, or removed (hard to do). We also have OE-level training and advanced diagnostics, including reset adaption, adjust/reset of the throttle actuator and EGR valve coding. it just has that low end stuuter. Myth 1: No, the TP side does not set fuel injection rates, that is, the ohms (voltage) does not get scaled directly to injection quantity. ( I will cover 92-98 1.6L 16valve MPI method here) A GO /NOGO method this is called. The below graphic is for the OHMS test, but in fact this same drawing showsyou, what pins to test for the live voltage tests. 2.Misadjusted or bent throttle linkage.You don't know what was done before you got to it. Back probe pin C. (at factory side, blue-white wire, ) This is the calibrate pin, and we are only testing now, notCalibrating yet. TheNincompoop section, there areno limits to damageor people doing crazy things to cars, wrong parts, or damaging them. The FSM instructions, are are linked in every section on calibation and does cover this step. (about 300k) is adjusted incorrectly (throttle being held open too far; more on this later), There is a problem with All EFI engines like this go lean if the driver punches the throttle, all do (dead TPS), ( due to that slug of air is INSTANT) then the AIR meter sees the change late. With the IAC valve Plug in the scan tool to the ECM. (put the. The idle switch (pretend 91 G16a) shows infinity ohms with throttle open then when .016 gap (.4mm) happens the OHMS drops to 500 or less like a shot, some do this at 1000 ohms, we calibrate near 500 but is crude, just get it below 500, a touch. Once the driver is properly positioned, tighten the Allen screw to lock it in place. Idle switch OHMS. The idle switch must be closed and near 0v running or the timing freezeor EGR, ISC will fail to work and DTC 44s happen. it must not be stuck at 5volts. Test 1: Pin A, power pin test.
