Shop Discount Throttle Position Sensors

i was wondering if your throttle position senser os bad can it affect your auto transmission shifting going out of wack?

Yes it can. It is more dependant as to year, make and model as to how much it will affect it.

2004 chevy trailblazer-4.2liter-78k miles
Wifes truck--She called and said the truck was all of a sudden running real sluggish.....max speed 5-10mph-Has had "check engine"lite on for about 3-4 weeks---Just now when the sluggishness started .....this message was replaced with something like" low engine power" or "reduced engine power"-diagnostics check by uncertified personnel revealed engine codes relating to the throttle position sensor......it appears that there is one located on the throttle body and possibly one @ the pedal????? If so..........how do i determine which sensor.......and how hard is it for the average unmechanic guy to change out the sensor on the throttle body? I don't even know where the throttle body is so you get an idea of how much of a mechanic i am..........and is it possible for it to be a fuel filter problem? Thanks beforehand for any help on this matter.

Thanks again for the quick response. One more question.....so i have some sense of how this works.............how would i know if i had to replace the "other" sensor? Once again.....thanks beforehand.............

They are both together in one part so you don't have a choice.

Great......first time i've used this type of site for anytype of repair or diagnostic information.........looks like it works great............

Okay this is the story on the camaro...

The car would start fine but as soon as you give it gas it dies. Would this be attributed to the E.G.R valve? It dies as soon as the gas pedal is hit. So i was thinking about checking the throttle sensor too. Any info would greatly help, thanks.

Check fuel pressure and the throttle position sensor. If fuel pressure is low, it will idle but not allow enough fuel for it to accelerate. Changing thwe fuel filter may be a good idea. The throttle position sensor can also cause that problem if it is broken inside.

starts fine,once started it revs up to 4000 then drops to nothing, does this for 2-4 minutes EVERY time i start it. Replaced throttle positioning sensor, Advanced says its the 4 o2 sensors. now when i get up to 25 and it tries to go to secong the rpms keep going but i go no faster, have to lift until it shifts, cant floor it at all no matter if im sitting still or trying to pass someone, is this the trainy. got trainy filter and fluid to replace today

once they said 02 sensor i stopped listening. its more serious then a sensor. b4 that they even said the lid on the gas tank. they r no help. replaced throttle positioning sensor because of them, no help there. my thinking is going towards the junkyard

I have a 95 Grand Am with the quad 4 engine.It idles good but the gas pedal feels jerky, the engine light comes on and stays on after 7 seconds, and gets lousy fuel mileage.The code said that the throttle position sensor was at fault. I have replaced several without improvement. Any suggestions?

Take a hard look at the wiring and connections to that TPS and connections of anything that looks suspicious,
