Throttle position Sensor

I am replacing my throttle position sensor, and after a visit to pepboys(wrong sensor) and Auto Zone(wrong sensor) I finally bit the bullet and went to the dealer. They gave me the wrong sensor to. Looks like my 97 4.0 TJ was assembled with a 1992 2.2L throttle sensor? Just in case anyone else runs into this problem, this may save you some time.

Weird, my 2002 was assembled with a 2003 TPS! What a PITA it was to figure that out

My dealer always request the full VIN to ensure they order the correct part, never had a problem. If yours does not they will just take a guess and your money.

How could a '97 TJ be assembled with a '92 TPS? I don't think that's a factory part that was in there.

Are you the original owner? Could the TB have been changed (would a 92 TB even fit and that would be a 2.4)

Wouldn't that still confuse the PCM? I feel the resistance values of the two TPS units would vary

I don't know how it happened. I am not the original owner, but this part didn't look like it had been changed out in the past. The electrical plug didn't even come close to fitting the correct TPS for a 97. The jeep runs fantastic now with the odd TPS and a good throttle body cleaning.

Initial build 1997 TJs like yours and my 3/96 build '97 TJ often came with sensors used in the '95 Wrangler YJ. It was later in the '97 build that they switched over to the newer/different connector styles. I had the same issue with mine.

Thats crazy, sounds like my old chevy truck. It was a '93 Chevy Heavy Half Z71 Cheyenne, turned out it was a special order from the factory, getting brake/suspension parts was a real pain in the butt.
