    Default Check Engine Light - TPS code returned

    I have an '02 Wrangler (4.0L) and the check engine light came on. the good friends at auto zone ran the code and it came back as the Throttle Posistion Sensor. Has anyone else encountered this problem? If so how hard was the swap out of it?

    Last night I attempted to replace it myself but I swear that they the screws were put in with lock tight. Also, the connector that plugs into the the TPS snap the holding piece. Does anyone know a good place to get Jeep parts - i.e a junk yard? Or is there a site on the internet that would specialize in older parts like that? I contacted the local Jeep dealership here in Montgomery and they said that those parts are carried or even supported in a sense.

    Might try Quardratec http://www.quadratec.com/ 1-800-745-2359
    or 4Wheel Drive Hardware http://www.4wd.com/ 1-800-555-3353
    for a new part. Most likely it's part of a whole assembly though.
    Also try PM'ing 'crazy4ink' on here. He has a shop up in PA that who knows what he has around there. He's been pretty good to go with advice for me and my friends.

    Changing out a TPS is not diffucult. Once you take the electrical connection off, there are only 2 screws. The biggest thing is getting the new sensor on the butterfly and then clocking it against the spring while you start the 2 screws.

    Try www.jeepareus.com for the connector you are looking for. They are a Jeep only recycler.

    Thanks for the plug Yeti. I'll look around. We mave have the plug that you need laying around.

    05Warrior changed his (IIRC) while we were on the way back from a trail ride in an auto zone parking lot with some simple tools we bought at auto zone for 5 bucks. a haynes manual helped a lot, but it seemed pretty straight forward.

    Have you applied the busted knuckles with a beer or two? Also Lefty Loosey Righty Tighty Sorry couldn't resist.

    Most likely they might have used one than compounded engine heat went and cooked it up tighter. Don't know if some PB Blast would work here, never changed one myself.
