TPS reads"fault" at rest

Like it says, is this normal? At rest the on screen info alternates between fault, and 0%, same thing when I put the pedal to the floor, 100% then "fault". I just never noticed before. It is at the extrems of travel though. Ther is also a tiny bit of play, as the plastic has worn a little where the shaft goes into it, less than 5* I'd say. Can I (should I) just epoxy it in the "0" position at rest? thanks, Carl

This probably means that your TPS is probably going beyond the range of the calibration. Have you properly calibrated it? also, if you turn the idle air screw on the throttle body, this will merit recalibration of the TPS again. Also, please note that everytime you recalibrate the TPS, the throttle pump settings will be affected.

carl, make sure you lube up the throttle linkage really well, then calibrate it again.

if it was sticking--even ever-so-slightly when we calibrated it last, then it returned to a rest position lower than that (or if you lowered the throttle stop), it'll show fault.

it's not a really big deal and won't effect anything when the car is moving. just recalibrate it and see what you can do about the play in the sensor.

I lubed the assembly(throttle linkage), and I had to relocate the throttle cable, due to some interference. It is only off by ~1*, so I think it s/b fine. Thank guys.

As the others have said this is normal and doesn't effect anything. If you back the idle adjustment screw out a half turn, recalibrate the TPS, then turn the screw back in it will show ~1% throttle instead of the fault code. Just something I do to avoid the annoyance of seeing FAULT.
