As far as i can understand normal operation should be:

Closed Throttle = 5v
Slight movement = 4.4v
Straight slope graph down to
Open Throttle = 0.5-0.3v



What i have measured in my car L6 with PF01 TPS (Tried 2 of them and got same result !!) is:

Closed Throttle = 0v
Slight movement = 4.4v
Straight slope graph down to
Open Throttle = 0.5-0.4v


Does anyone have an explanation as to what is going on. Like i say, i have tried 2 different PF01s and both give the same results.
Are BOTH TPS faulty and this is what happens when they fail ??? You loose the 5v signal at closed throttle ??

Advice appreciated.

thanks
