What did your car do? What were the symptoms?

I've searched a bit on this for customers cars, and have only found bits of information, though it's a seemingly regular problem. Perhaps this could be sticky-worthy...

a badly adjusted one might also give similar symptoms.

not sure on the FD as these are mostly FC stuff but i would look for lousy throttle response, hunting idle, idle that is high/low, gas milage useage (abnormal), and the smoothness of the power band and reving.

 

recently i put my stock ECU back into the car and noticed a check engine light. after a quick diagnosis i got code 12, which is for the TPS. however, i checked the voltages for narrow and full ranges for open and closed throttle...all my voltages were in spec, however, even after resetting the ECU, i still get the check engine light...not sure if the ECU is bad, or maybe the harness is bad. any suggestions?

 

check the sweep

they are variable resistors and can have dead spots.

but wiring is a very possible cause

 

These are not necessarily symptoms of a failed TPS, but more of an out of adjustment one so they may be similar:

my car actually runs fine...i don't have any symptoms...the only thing is that check engine light. the only thing i have is when the A/C is turned on and the car is idling, my RPMs fluctuate between 900 - 1200-1500, but i've been told that is a different problem.

 

no one else's TPS has gone bad? This could be an excellent resource thread for newbies....
