Tighten the two bolts in the sensor so it will no longer move. Once the driver is properly positioned, tighten the Allen screw to lock it in place. (I will use harness side colors, because they do not change) This test is long, but is better than guessing and paying $250 for a new sensor !! NOTE: If you get a Check Engine light error indicating that a TPS failure, it is most likely caused by not having the TPS driver nut in the correct position. NO MPI engine G16B has such a device. Never adjust the painted or capped off,throttle stop screw, for any reason. (silently; no DTC) (if the angle is at say 4v , the ECU thinks that is not an error , just the driver doing UNflood mode per operators guide) installed the TPS following the directions posted elsewhere on the site. DC voltage is measured between pins Sensor (+) and Ground (-). It is just some quick Checks,looking for the hard failsfirst. Connector pin out. ECM or PCM) There are many failures on the EFI system that can seem like a bad TPS and is not. Idle switch OHMS. The TPS was calibrated using the wrong feeler gauges, as seen on many store, rag books or on line. HowTO Replace Your Throttle Position Sensor 1. Plug the cable leads into the TPS sensor. Remove grounding of the Adjust the TBI. I probe pin C ,key Onno start,, and the Dash Pot is holding the throttle open now, (if not fix that now) and the voltage is 0vdc, ( 0.5v) (minimum air setting). Test 1: Pin A, power pin test. NOTE: On (A/T) models, connector terminals are identified by air will always be allowed to enter the engine around the throttle valve. The 8V TBI below: TPS calibration point. Pin 2 must be below 500ohms key off connector off. The connectors are held in place with locking tabs, so you'll need to use something like a flathead screwdriver or a small Allen key to release the tabs first. To start with, turn the key to the on position and then find Go EFI Tuning on the main menu and press enter. (my short list, lol) THE OHMS test. Part 1 of 2: Removing the throttle position sensor. What Does a Throttle Position Sensor Do? 1986-1982 2.5L (R) 151" 17068996, 17078274 TBI 14050 Skyhawk 1982 1.8L (G) 110" 17067587, 17068612, 17078516 R-2 CARB 14053 This is what needs to be turned to adjust minimum air, or more commonly known as "idle speed". Open = infinity, (meter shows , infinity ohms) There's nothing to adjust. ouch) Never hot wire any output pins on any ECU. It allows air to bypass the throttle plate. See 1989/90 procedures here and quite unique. CASE 3: The multimeter DID NOT register any voltage. Turn ignition switch is "OFF' wait at least 10 seconds. and CAL means you get the switch to just close, and you stop turning the TPS body. What is it, what does it do? 2.5l TBI. (or to the engines shinny metal) For a ground reference. Backfiring. (4vdc on TP pin) all injections cut. (engine races at idle) Say you look in the throttle bore and the TV is not closed (with dashpot retracted on TBI). Removing Your Sensor Follow these steps to replacing your sensor. This program lets you connect your laptop to the ECM to conduct data logging sessions while driving the car. GO = Closed IDLE switch ( less then 300 ohms) (300 ohms is TPS spec, , ECU spec, i think is 500) I use 300 ohms. The TPS is now calibrated and validated. on the throttle blade or throttle body bore, The throttle stop screw You will need a couple of paper clips or pieces of thin solid wire to reach into the back of the TPS connector when its plugged into the harness. The ECM resets the IAC valve when the car is Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound. PHOTO 3: 92-98 look same. edicts. on those cables is 10mm slack. TPS Adjustment procedure 2005-2010 XPs: By: commanderjjones aka Jerry _____ TPS = Throttle Position Sensor: The TPS is located on the passenger side of the throttle body. ( I corrected and error here.. shame on me) After adjusting the throttle stop screw, it may be necessary to adjust First, put in Your key and set the ignition to RUN for 3 seconds. (if the ECU sees this , it can SET DTC errors for IDLE Switch failure,when in fact is just calibation errors), 1991 to 1995 , 8V TBI G16a TPS Calibrationof TPSidle switchside: C and D. The 3 video tests (mp4). Thedash potdevice must be retracted engine running. Unscrew the TBI's bolt with the wrench and pull the TBI from the car. The TPS switch is not closed at idle, for any reasons. It should be mounted to your throttle body, which is on top of your engine. what do you mean? neutral (manual trans). If you get a Check Engine light error indicating that a TPS failure, it is most likely caused by not having the TPS driver nut in the correct position. If the meter does not read 5 volts, the TPS is bad. Adjust by rotating Throttle Sensor body so that the output voltage is 0.45 - 0.55 volts. You may cause the throttle to stick open. (this will require the IAC to open further so the engine gets the required If the screw was MONKEYED and you fix that first and off car the throttle cable cant interfere with the calibration. The idle switch is the only device calibrated here. The throttle body costs between $200 and $500, while the labor cost is around $50 and $150. Home > Engine > Sensors > TPS testing and calibration, all Sidekicks and Trackers. Close the hood of the car. That would put the main line pressure to maximum. Test the voltage of your TBI using a multimeter. o2 sensor. (Accelerating he/she is?) Hit the Exit button on the configuration box. Key off: Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. If not unplug it and check it with the TB closed. Shut the engine off and locate the AWS hose in the back of the carburetor attached to the curved inlet pipe near the throttle arm. I have no attachment to the c. The Feeler gauge Matrix Table 1: (created from all origional FSM manuals (factory service manuals) Suzuk and GM.) DTCs? Take note of the rpm when the car is in park. The ISC willfight your right footin a very strange way. or when your stopped at a stoplight and hit the gas a little it sputters for a sec or two the runs smooth. Throttle Position Sensor 1991 Chevy Silverado Throttle Body Idle issues SILVERADO BLUES MEMBER 1991 CHEVROLET SILVERADO V8 2WD AUTOMATIC 89,900 MILES I just completed an installation of a 400 SBC into my 1991 Silverado C3500. There are exceptions to that. (aka SPI ,er, single point injected, bla bla) This TBI 8valve device (back side of Throttle body) must be retracted someway to do the TPS calibration. (but the idle switch , yes idle will be wrong if the switch is dead.) The 8V factory TPS data pages: Make sure your DMM meter is working ok , first. maintain a set idle speed. I've got an '89 and used a scanner to find out my TPS was shot. Ground the black multimeter test lead on the battery negative (-) terminal. Off car, you see the plate is not closed or is full of gunk blocking it open. (0 volts connected on a running engine at idle (hot)) Adjustment is not possible. When working correctly it used to read 0.65v at idle and the "new" one which replaced it reads about 0.56-0.58. It can also be used with the car's ignition turned on but the car NOT running to check other data relative to the TPS. Then if you open the throttle another 1.28 degrees, the throttle vane is actually open 2.20 degrees but the Motronic reads 1.6 degrees. With your laptop connected to the ECM Data Plug, open the WinALDL program and turn the car ignition to the on position but DO NOT START THE CAR. The POT side TP SIDE: For a better experience, please enable JavaScript in your browser before proceeding. and it will work. For Over 100 Years . DMM/DVM: meter set to 20k Ohm range: See Figure 2 above for pin locations. STOICH: (means perfect fueling) that happens in Closed Loop mode of the ECU. (except 89/90 years) use tie wraps or bailing wire to tie it back some way. automatically learns the closed throttle voltage when the ignition is keyed on Theidle switchwill be below 300 to 500 ohms or near0 voltsidling (lower ohms, is ok , higher not, when at idle) {mine reads 50 ohms } (89-95 years) MPI is 16v Multipoint Injection motors, and has no Dash pot steps, or device. 1,2,3,4, bottom up. Make sure the throttlefully drops the butterfly and end crank against the stops,there is a screw there, that bottoms out, do not ever touch that screw. (hand vacuum tool, tie it back, or removed (hard to do). The throttle stop screws primary function is to This was. (warning the TPS actual wire colors can vary, but not the car harness colors that dont. Use a hand vacuum tool to retract it for calibration. Set the scan tool to TPS voltage (or connect DVM) then set the adjustment screw for the lowest value & still touching the throttle arm stop. If your Ford Ranger has a bad throttle body, it can cause it to run terribly. Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver. Common symptoms of a bad throttle body include, dirt and grime, the check engine light, and an erratic idle. the cold start fast idle device ) The VSV (vac. The same for cruise option cable. To check that the TPS is getting power, go to: TEST 2: Verifying Throttle Position Sensor Has Power. With the IAC valve If not get one of the HAYES or CHILTON manuals manuals and do some reading. If it fails on TB and is good off body, , TPS was mounted WRONG ! 1985-1992 Firebird 305 and 350 TPI. Throttle Position Sensor adjusting the easy way! Pull the air duct off the throttle body. engine around the throttle blade or thru the IAC passage at idle. it must not be stuck at 5volts. Once youve downloaded and installed the program, configure it per the directions below. (using 20k meter range) never reads infinity. (varies by maker of DMM) Only the Dashpot on top left of TB throttle body, is allowed to do this. You must adjust the throttle stop screw before you attempt to adjust the TPS. (will not attain 500 ohms or less) (if 8v DP retracted) (even fails in hand removed? If the throttle body has been removed (i.e. Measure the TPS with the multimeter once more to make sure the new settings have been achieved. ON means the switch is closed (very low ohms ,Typical. Adjust the TPS sensor by reading the ranges of the high and low increases and adjusting the bolt on the top of the sensor until all four readings are in the normal range according to the meter. On a running engine the idle switch reads 0v. 500 or less) up to a max of (3000 to 6500 ohms), as you move throttle from min to max. TheAnglepin is used for fast throttle enrichment detection and to detect cut throttle. special tools available that are designed to test GM IAC valves, but I have Today we're replacing, and adjusting, a throttle position sensor. ( it shows what your right foot is doing, only) 92-98 Again, the 3 throttle cables (up to) must not be tight. (ECU sees, idle switch closed and RPM is a 4000 RPM, and low plenum vacuum..oops.?). Engine idle controls dead, the RPM dont hold at. Then, start the car and try to rev it up to approximately 3,000 RPM. 1 Throttle Angle Pot. At idle, its .54 volts, which i think is correct. There is increased load (on other features keyed off this line, EGR enable, and doing spark timing the freeze jumper fails to work.) unbolt that nut below (stud) and remove the DP for calibration. The only true 100% accurate TPS throttle angle test Pin B, is with a scope,to see all glitches.!!! (varies from 1v to 4v as you move the throttle, typically) Throttle Stop Screw neutral (manual trans). C and D Pins. The switch side is a bit strange, let me explain. Photo 5, do not attempt to do this. Eg. (the ECU idle serve fights the drivers actions) internal loads/friction which can also result in a drop of idle vacuum levels. Pins C . The idle switch must be closed and near 0v running or the timing freezeor EGR, ISC will fail to work and DTC 44s happen. DOA: Show and tell: (when things go wrong, never hit your TPS, oops , damaged , I bought a spare like this.! ) Lock down those TPS side screws. You must leave the connector connected,andus a back probe technique, to read the voltages. That means it can't calculate the fuel and air ratio. CAL steps) TV means Throttle valve inside the TB the Throttle body. Move the safety pin and positive wire to the 3F connector and repeat the process, checking the increase in voltage. THROTTLE POSITION (TP) SENSORS WHAT THEY DO Monitor the throttle opening for the computer to adjust fuel flow. The Fora platform includes forum software by XenForo. The IAC valve cannot be tested using conventional Pot. if the TPS delays opening, the idle switch , as you move the throttle pedal, a tiny bit ( .020) The ECU and ISC will fight you hard, and it willSURGEduring that fight. The code that showed up was P2135 which indicates a throttle issue. AnyDMMs meter can be very slow reacting, and miss them.! To help us guarantee the correct parts for your classic car. All colors are harness colors. (keyon or off , not started) Factory TPS calibration procedure for the 16valve MPI 92-98 Sidekick or Trackers. The TP does get watched by the ECU, for rate of TV action, you move the throttle fast and the ECU sees that and goes toENRICHmode, until the MAF/MAP catches up. MPI, the 16valve engine with the words 16 valves embossed on top of valve cover, and is multipoint INJECTED (4 injectors). The TPS was mounted wrong to TB side, and not indexing to the internal tabs , thus jamming the TV at idle and making TPS calibration . To adjust the throttle position sensor (TPS) of the Vehicles you must remove the Vehicles and alter its makeup slightly. Regardless of the side draft carbs being used, you must have 100% throttle rotation prior to installing the TPS. below is terminal 1 to 3 test for the POT test. TBI Adapters; Throttle Position Sensor; . repeat them all. Buzz words: Normally what happens, at ECU pin A14, it is at 0v at idle, then the driver moves his foot .020 (as measured at TB TV valve) and the idle controls are ended (canceled fast it must). Hold the TPS in place and tighten the retaining screw with the Phillips-head screwdriver. (the TV is the Throttle valve.) The 16v uses software for a Dashpot function. if this pin drops below 4% throttle angle (below about0.2Volts) driving, you will getDTC codes 21/22 errors. Check the tag on your ECM for its service number & then scroll through the ECM Type field until you find that service number. On a 100% factory stock engine, you should never Disclosure: I am not a mechanic. disconnect the IAC electrical connector. lean what infinity means by setting meter to 2k (200) ohm scale , with leads held in air. When the throttle is fully open, the TPS sends a signal to the car computer that controls fuel injection. This TPS was stuck in UNFLOOD mode, car will never start. Then put a load resistor 470k (yellow,Violet-yellow color code) on Pin B to ground, (resistor side one at B pin and the other resistor end to ground pin) 0v means idle, 5v means not idle. If idle speed is not okay after cycling system, problem is usually caused by a dirty throttle plate or vacuum leaks. (a fool proof calibration) All pins names and locations are seen inFigure 1 above. it just has that low end stuuter. This page covers calibration and testing , on car or off, volts and ohm methods. SPI Single point injection, by some. If not, remove it using a sharp pointed tool. With the ignition still on, As you can see pin 1 is the bottom pin. Best place for asking questions is FixKick forum. (DIZZY). If your Chevy Equinox has a bad throttle body, it can cause it to run terribly. (takes human testing to find this flaw, the ECU is very dumb here), Warning,(TPS calibrated to open late) Stuck at 0v means Pin A wire is cut or open or ECU pin A not at 5vdc, or the TPS is bad. ), If the TPS screw mount slots bottom out, here the TV valve shaft is bent or the valve stop screws wereVIOLATED,(, The ohm meter nowreads Infinity. Lock down the TPS side screws. Other pins open will throw over voltage DTCs for TPS. 2003 S10 Long Bed 4.3L ZQ8 + 2/3 drop, Caltracs, rear disk conversion, 7" dual diaphragm booster, 255/50/R16 Falken ZE-512, MPFI converted 2114, 48LB Racetronix injectors, eBay RS BOV, Accel 60115 distributor, Aeromotive FPR, Corbeau Forza seats, Mach headers, 2.5" front mount intercooler, Innovative turbo, Precision Industries Vigilante 3,000 RPM torque converter, EFILive COS3 tune. Select the Dash button which will open the Dash Display (Yellow Arrow). Very bad that. It doesnt have to be accurate , just consistent and linear. Step 2: Disconnect the negative battery cable. Plug the cable leads into the TPS sensor. (common on high mileage cars) It must not over or under travel. Not at all. The TPS, is dead because you have a A/T to M/T swaps or the reverse and done wrong, wired wrong or the wrong ECU used, for each. Key ON. These simple tests follow below: TheDash Pot must be retracted, when stated. (the volts must not glitch running or ohms when tested) (will not cause timing freeze to fail), Gunk under the throttle valve, in, under and around the butterfly plate to bore. The TPS switch, must open at the correct moment or the ECU will be very confused ! This is done with accelerator in the idle position i.e. Test the voltage of your TBI using a multimeter. The rule for WOT is About 75% and above Throttle angle is Unflood mode. (non 89-91) "Check . The original tps costs too much. The ECU sees VOLTS on this pin, and watches forfast changes to the voltageand never (cept cranking) uses the exact voltage to do anything. IDLE SPEED (4-CYLINDER) The ECM resets the IAC valve when the car is You need to back off the driver set screw 1/2 of a turn to set them properly. Adjust the TPS to 0.5v that is 1/2 volt, exactly. This allows the installer to simply and easily mount the TPS sensor and adjust it so it delivers precise throttle position information to the transmission controller. Pull the pin out of the wire on the sensor. To be sure,must guys just set it to .026 drive around the block and all is well. By the way, if idle speed is out of control ?,with the switch closed (0-volts) is coveredfound here. However, it serves Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped. Threshold is setting it, just so the switch has just closed. The pot side of this TPpin 1(bottom) andpin 3, varies from very low ohms (typ. throttle bore. No dash pot. 4. Copyright 2023 Leaf Group Ltd. / Leaf Group Media, How to Adjust the TPS on a 1994 3.0 V6 Toyota Pickup. The ECU will not set a code for Glitches. (off topic ) (over 75 % is WOT most cars) It it rare for any TPS to last the life of the engine. (this switchnever produces 0 ohms, but does go below 300 ohms for closed , ECU expects less that 500 or less, we think) The J18 engine first removed this device and on all future engines. (my comments are on a normal hot running engine). Remove it and check it. So there are 2 tests and only 1 calibration. I have seen new switches vary from 50 to 1000ohms (in the first .030 of travel.. the goes to infinity (and open circuit) NOGO= Open Switch. Be sure to wiggle all connections while watching scan data/voltage readout to make sure the problem is not a loose or bad connection. If they messed up the TV stop screw , here is the easy fix (see my crude solutions here). as seen below. If all is good, we can skip the calibration. or hackers messed up my car? S10forum is the community to discuss the S-Series, Chevrolet Colorado and GMC Canyon. tps. 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? 5. is 5vdc when not at idle and near 0v when at idle. The Advance must be smooth. means potentiometer or variable resistor. Myth#1: (all comments on a Hot engine) And either the IAC needs to open up or the throttle blade must be opened NORMAL. Measure output voltage of Throttle Sensor using voltmeter. TBI, the 8 valve engine with black top valve cover . (wild jumps or drops in voltage) Remove the air cleaner lid and the air duct leading to the throttle body using the Phillips screwdriver. The ISC will be dead ! The check engine light came on and I had it read at an auto parts store. PattonMachine.com 2020 Patton Machine LLC. The word crude is an understatement here even when your driving and just cruisin like 30 mph . can cause a code to set.
