XJ TPS life span

I have a '95 YJ with 60,000 miles and the original TPS. It is not a part that wears out by any mechanism I know of.

Well these are electrical parts, so exposure to moisture, excessive vibration, excessive heat, mechanic dropping it on the floor prior to installation, who knows?

Our 88 has almost 300K km on it on the original TPS.

I have had the TPS die twice on me in the last 3 years and yes we do off road it, so it sees muddy water.

On recommendations from folks here, I decided to clean it before shelling out money. I started with the easy clean and did the electrical plug with contact cleaner first.

That lasted over 2 years until earlier this year when it went 'bad' again on an off road run. I used WD40 on the plug again and away it went.

Thanks for the info. Next time I'll just try cleaning it first before I have them put in a new one.

When yours went bad, did just the check engine light come on, or did you start to have problems with the Jeep shifting too?

I have no 'check engine light', my old computer isn't smart enough for that...

And I have a standard, but my symptoms would have really messed up an automatic shifter too.

I was getting high revs on start with a stall at the first stop. If it started back up 'normal' all was fine, if it chose to start back up with the high revs, then it would crap out again.

On that run this spring, it was stuck at +2000 rpm. Man on the ATV trail we were on, screaming along at 2K was 'not' fun. The brakes started smoking from me trying to hold it back.

I gave up trying to restart it to get it to drop and got out and cleaned the thing. Bingo, instant nice idle again.

My wife mentioned she thought it was back up a bit yesterday, so I need to do a proper clean and put some fresh dielectric grease on the plug's rubber seal rather than the quickie 'trail fix' I did with WD40.
