Bad Throttle Position Sensor - Symptoms Explained | Signs of failing throttle position sensor (TPS)

[@dustintunis9347]

I'm pretty sure the check engine light only flashes when it is actively misfiring.

[@larrythomas3624]

My 1993 F 150 started idling way to high ( no tach but probably 1400RPM ). I unplugged the TPS and the idle went to normal. I drove it around the block with it unhooked and it actually drove ok with it disconnected (?!). I take it that I need to replace the TPS but it seems crazy that it idles and accelerates pretty decent with it not hooked up.

[@vincentthomas4728]

Hey did it end up being your tps? I have a 1996 cobra and it seems like when it’s warm it’s bad but cold it’s running fine

A Bad tp sensor does increase idle rpm or random stall...but there are other reasons like chocked throttle body, vacuum leaks etc

[@jeremypilot1015]

This may be what is wrong with my 2002 VW Passat 2.8 GLX wagon. When i am cruising between 30 and 40 with slight pressure on the pedal, the engine will start surging up and down only a few hundred RPM and when I hit the cruise control it stops instantly. So it can't be the transmission or torque converter. This makes sense if the throttle pedal is sending a bad signal to the ECM those bumps could be from the ECU pumping fuel to the engine when it doesn't need it. It's a rhythmic pulse too which would fit with injector cycling

[@thomaswilliams2780]

Possibly look at the MAF sensor as well I have a 2000 Astra 1.8 that hiccups under acceleration, unsure what's doing it, but symptoms of both TPS + MAF sensor failure are present

[@jeremypilot1015]

@@thomaswilliams2780 yeah I can assure you it is the torque converter. The fluid is shot and that is causing the lockup solenoid to disengage when it's not supposed to. Changed both MAF and Acc Pedal still persists. Issue goes away when I engage cruise control, because the ECM is commanding the torque converter not the transmission fluid.

OK, now I'm more confused than ever. In all the F-150 forums, guys are claiming that changing the TPS eliminates the hard shift between First and Second gear in the E4OD automatic transmission. I'm not seeing how based on this video.

[@junebug9261]

05 Eclipse having problems only when I press the accelerator down rapidly car begins to sputter and also at idle what’s to die once car is at operating temp.I have used a DMM to check voltage on TPS and is .5 volts reversed the ohms and pushed the butterfly open from 0-100% and went up from 0.7-2.34 at full throttle no spikes.But throws a p123 code for low voltage to TPS. Wondering if it’s false reading while car runs then when it’s operating ? Side note new battery new alternator new plugs also car runs at operating speed fine just no fast acceleration. Opinion please.

[@renanperez1616]

I just replaced the Mass flow air sensor on vw Passat and I reassembled the throttle and everything thing else, but I just noticed that the engine shakes a little bet. Do I need to connect to a computer and reajuste the airflow to the intake?

[@autoinfogroup1629]

Hi there, if you reassembled the throttle body, could mess up the calibration and might need a recalibration. Also clean the map sensor too and the egr if equiped.

[@autoinfogroup1629]

Hi there, this can happen if the accelerator pedal sensor, throttle position sensor or the valve actuator. any one has an issue. Its a good idea to scan the vehicle to see the codes generated. So the particular device can be repaired.

[@bawzworkz5574]

Well, after failing Emission regs, removed my spark plugs to check the insides and found a load of unburned fuel on the pistons. So I replaced my sparkplugs, Cat, O2 sensors, used injection cleaner additives and still failing emissons, this is my last hope. Lol.

[@alexisdietz6199]

Hello! (I apologize in advance for the long post) I drive a 2019 hyundai elantra SE, last year around june or july i was traveling for work. I was taking a 5 hour road trip and when i came to a stop after driving a couple hours my car wouldn’t accelerate when i tried to go again. I had to shut it off and turn it back on for it to go again. It didn’t happen again til a couple months later or only when i would take long road trips but over time it started happening more frequently. Fast forward to 2 weeks ago i got it scanned at auto zone and the camshaft position sensor code (B) came up. A week after that I came to a stop and it happened again but this time when i shut it off, it wouldn’t start back up. Someone gave me a jump but it didn’t run for long. I was stuck on the side of the road for a couple hours and then it finally started back up. I made it to my house but the whole way there, every red light i came to I literally had to put it in park and keep lightly pressing on the gas or it would do the same thing again. when i got home i tried starting it again and it was shaking and wouldn’t stay on without me pressing the gas. It sat for this past week and 3 days ago i got the camshaft position sensor and my brother put it in and still nothing. Had a mechanic come look at it and i he told me to take my battery to get charged and my brother put the sensor on the wrong one. Battery was bad so i bought a brand new one and put it in and had my brother fix the sensors and it still wont start. The engine is also shaking when i try to start it (will attatch a video below) my brother says it will only turn over when he is pressing the gas. (will also attatch a video of what it does when he is not pressing the gas) i sent the videos to the mechanic that looked at it and he said it sounds like the fuel pump is bad. He came and looked at it again, checked all the fuses, and fuel pump and said they are working fine and is convinced the tps is bad but no codes are coming up. Could this still be a bad tps?

[@autoinfogroup1629]

Hi there, As theres no codes or anything from tps. You can use an obd scanner to check the applied throttle position reading and actual position recorded by the ecm. If its under calibration, you might want the old mechanic ways. Start from the air intake. Check the air filter, clean the maf n map sensors, clean throttle body and check if its moving according to the throttle given or just oscillating, check for vacuum leaks like loose hose, broken pipes etc...Next the ignition...check the spark plugs. Check the injectors pulses. Also if the crank position sensor is failing can give you such issues without any codes.

[@zophni5904]

Having this issue.. u find out?

[@CommonSenseTipsAndTricks]

That is exactly the problem I'm having. The vehicle does not know which gear to shift to! It's sometimes it can't find second or it might find third. But I know I have a bad TPS because my check engine light is blinking all of the time. Before when I was driving the van, it would jump ahead of itself from first gear. But now it can not find second gear. I think if the TPS is bad, the ECM will not give the signal for the shift solenoid in the transmission to go into second gear.

[@urdad849]

@@CommonSenseTipsAndTricksI’m having same issue with my car

[@autoinfogroup1629]

Bad TPS will cause hard shifting or non shift at all....thats because, while shifting, ecm regulates, engine rpm for smoother shift. this is done by regulating throttle body from the values of TPS. If the speed is not monitored, you will get a hard shifting and some times, delayed shifts.

It idles and starts fine, but will not go over 40mph on level road, and takes a long time to get to that speed (severel minutes). It will be fine one moment and then begin this malfunction in the middle of driving it, in town or on interstate. I do have a TPS sensor code (P2135) but also cam and crankshaft sensors codes. The timing system is fine and it doesn't jerk or do anything strange except refuse to accelerate. I can turn it off and after 20 minutes it will operate fine again. Is the the TPS sensor getting hot and then it fails?

[@norisboren5402]

Some people disconnect the blk. battery cable for 30+ minutes to remove power from the vehicle computers. Then after 100 miles (or a week) of driving have got back better gas mileage. However you will have to later put in favorite radio station numbers, so write them down first. Hope helps. Of course having enough tire air pressure (see maximum pressure printed on each tire & on driver door), replace air filter, pour fuel injector cleaner in gas tank sometimes, fuel injector leaking or one bad possibly. Have mechanic check wheel bearing spin.

[@xbrutal3953]

Can happen though. A failing injector or ignition device too can cause the same issues. Do clean the throttle body and air intake sensors, replace the filters if too old.

I have a 2006 Chevy Impala 3.9L. Yesterday after coming home from a store car stalled. Went to start again and it cranks a bunch before turning over. It starts. RPM gauge stopped working when this happened. Runs very rough, seems like it’s not getting gas but it does eventually and then it goes. Runs ok once it’s moving. Did not stall again afterwards. Day before this happens my foot was on the break and car tried to go on its own.

[@autoinfogroup1629]

Hi there, this could be a bad crank shaft sensor or ecm wiring fault. If the rpm guage has a diflection, its likely crank sensor. Also car tends to accelerate own its own. This is most likely to cause but there are other reasons too.

Hi there, This could be anything from throttle body, air intake metering sensors, vacuum leaks even from evap system, any restrict in exhaust, crank sensor abt to fail, low fuel pressure either by filter or pump. if you don't have any other codes stored need to check all these areas one by one manually. Also if the vvt solenoid is not oem spec, could cause problems.

Here two things to look after, if the car rpm goes high but wont move unless it gets to peak rpm, then the transmission should be at fault. If there's no rpm or the vehicle idles unless its pressed hard to rev up, then the throttle sensor could be at fault. Do check the transmission fluid too.

Hi . Could this be affecting why my MPH falls randomly as I'm driving? I've replaced the instrument cluster and the inner speed sensor and inner speed sensor..I had a tune up done as well. And my rpm idle control valve replaced as well. It's just my speed drops to zero as I'm driving and I can't see what speed I'm going. I even replaced my catalytic converter..so looking for suggestions because no mechanic can figure why my speed doesn't match the computer and randomly falls to zero

[@autoinfogroup1629]

Did you mean the vehicle speed sensor? Normally this happens when the vehicle speed sensor starts to fail or the wiring to the sensor or to the cluster has a damage.

[@couchrider6228]

You have spent a lot of money on parts you didn’t need . A speed sensor is all you need. I would give much thought about getting a different mechanic. WOW.

[@shadf7902]

Bad.grounds can do that. Its a free fix basically.

[@Learn4successdgeff]

Where you able to solve your problem, I also have same issue with my hyundai accent. But not only the MPH drop. Everything on the cluster drop, temperature gauge, Fuel gauge, Acceleration gauge all drop at the same time and later goes back to normal , and break light will also turn on and go back. I tried so many electrician and they seems not to identify the problem.

I'm experiencing all the signs with my 06 Honda Civic. At the moment, the throttle isn't working again, if i try to accelerate it will stall immediately with the check engine flashing. I contacted my mechanic about it but he told me the TPS can't be changed alone, that I have to change the whole thing. I don't know how true is that. What should I do?

Yes its a bit difficult to find sensor alone. Could search online if its available but specific on the part number.

If you have found the part, just that part must be replaced. You don't have to replace the complete assembly. You might need to calibrate the sensor with pedal angle thats ol.

My issue now is that, my rpm always stay low even close to 0, I've spent lot on it for cleaning of injector, changing of plug, and all but still the same at idle, just watching this content now, I don't know if this could be the issue and I'm also scare of changing it and not be the issue, I would be wasting money buying it again, pls what should I do

[@autoinfogroup1629]

Hi there, if your car idles less than 500 rpm it stalls. Make sure your rpm meter is showing correct readings. Some meters shows calibration issues and shows less rpm but the engine runs good. If this is not the issue... most low reving n stalling happens because of failing TPS or Idle controler or even throttle valve actuator.

[@mitchwells4990]

My car starts but idles hard when I hit the gas it spits sputters and top speed is maybe 5 it's on the side of the highway now

[@autoinfogroup1629]

Hi there, this could be anything from, throttle body controller, position sensor, a vacuum leak even chocked intake or exhaust. As of vaccum leak, evap system can also be a suspect.

[@dereckc9469]

can a tps fail intermittently? seems to only happen sometimes I hit a dead spot and the car bogs like its going to stall but goes right back to normal. I try wide open throttle and the car doesnt move, feels like hitting a rev limiter.

Hello, my car is diesel and has unstable idle in the summer when hot, no problems in the winter. When the idle gets unstable I hear knocking from the throttle body. I have already cleaned the throttle body and the EGR but no improvement. Is it possible to have problems with the Throttle Position Sensor only when the car is hot and the weather is hot?

[@autoinfogroup1629]

Hi there, unlike petrol heads, diesel doesnot depend on the throttle or major diesel cars dont have a throttle but has an ASV for smooth shut down and escape engine runways. Clean the air intake sensors, check the injectors for any fault. If the injector solenoid is heated especially when summer can loose its minor potential and cause jumping rpms. Also check and clean the crank angle sensor too.

[@shanegoodman4924]

What if my transmission isn't shift properly

[@autoinfogroup1629]

May be, the speed range sensor might be failing, a bearing failure, hydraulic valve could be in issue, most commonly bad fluid or incorrect fluid.

I'm facing a similar problem in my my 2011 Ford Figo. While driving the car acceleration stops and pressing the pedal had no effect. Happened thrice in last 2 weeks. I managed to stop the vehicle to the side of the road. The engine didn't stall ,but was idling in all three times. After few engine restarts I managed get the pedal working. Is this sign of failing tps sensor? (When this was about to happen I also noticed the car jerked when I take my foot off the accelerator pedal which was strange. After restart this symptom went away).
