Just the other day I noticed a dead spot at a certin throttle position. It usually does it when it's cold outside, in the mornings is when it's the most noticable, it also does it at night but not as bad.
I'm thinking the TPS my be going out or may have some moisture in it.
Thoughts and ideads???

Thanks

Yep, I'd go ahead and replace the TPS, but you can always check it with a volt meter.

I found out that my neighbor has a OBDII analyzer and it came up with TPS code. I need to pick one of those OBDII analyzers.
$54 is what I paid for a new TPS.

What I'd like to know is, who's the BUTT-NUGGET that idea to put thread locker on the two torx screws destroying two of my T20 bits! Finger

Just an up date...I guess there two types of TPS's for the I6 and as you guessed I got the wrong one.
They are both 3 prong plugs and look very similar, but the shape of the my OE plug is oval and the one I baught was kind of squared off in the corners with some plastic tabs between the prongs that wouldn't let the male end of the wire loom go in all the way.

I wanted to add that I learned (from my local Napa guy) that at some point in '02 DC changed the TPS, The one that was equipped on my '02 (oval plug no tabs between prongs) is considered an '03.

He also added that, it will run without the TPS, but that the gas mileage will suffer. Also they do wear out at same spot that you keep your foot the most.

Hopefully this helps for future reference

Yet another update
The TPS seemed to be a dealer part, and they did confirm that mid year '02 the TPS and other sensors were revised and updated, thought he didn't say what month the updated sensors were installed.
I can share this, My TJ was manufactured in 2/02 so any TJ after Feb. is considered an '03 engine.

For future referance

This is good to know.

It seems a number of problems are stemming from a bad tps sensor. Mine also has the dead spot in the throttle, as well as a couple of other tps symptoms. One trick I've learned is that the irratic idling acts up if I work the Jeep hard. Sometimes, I rev her quite high quite suddenly spinning around in the snow. When I do this, the throttle gives me a hard time. After a couple of days of "Sunday" driving, it settles back down.

All very strange.

I also had that problem. One instance was I when I was approching a stop light and started down shifting in to second and I didn't realize the idel was about 1200 rpm (radio at an excessive volume) and kept me going about 20mph or so making me almost hit a car in front of me.

Also, all of these problems happend before the "check engine" light came on.
