TPS Sensor

So I just replaced the TPS sensor on my 97 Wrangler SE and had the check engine light reset. About 2 days later the check engine light came on again and when I checked it again it was for the TPS sensor. I did double check to make sure that the sensor was correct for my jeepers.

Any thoughts on why it keeps faulting?

I had a TPS issue once where it said i had low voltage I had bad luck with the Borge Warner TPS it made me have erratic idle and high idle. I disconnected battery and touched the terminals together like suggested to clear pcm capacitor so it would relearn still no luck. Ended up going back to my original and its fine. May try battery cable trick. If no luck there I would go with Mopar part. Ive hear of a lot of problems with parts store house brand TPS.

I've been through 4 TPS on my 97 recently.
Original TPS stopped working so replaced it with an after-market TPS - worked OK for a short time, then crapped out.
Replaced with another after-market TPS (Crown). Same deal - worked OK for a while, then crapped out.
Then replaced with a genuine Mopar TPS 6 months ago - haven't had any problems since.

Try disconnecting the positive terminal, then shorting the wire to ground. This will reset the ECU. I had a similar issue when I replaced my TPS, and this replaced it.

If you're going to buy aftermarket sensors the ONLY ones that are as good as the Mopar sensors are sold by NAPA. The Echelin brand is good quality. I bought my TPS from them over a year ago and had zero problems after replacing mine.
