Newbie (not exactly) but have a question...

Hi Guys - I was a ZJ owner for years (94-04), it was a great truck. I've recently bought an 03 GC Laredo I6 with only 50k miles and love it .

Yesterday my CEL came on, I went by my local Auto Zone and had the codes scanned - P0123 (TPS) & P1281 (Low Temp.)

I'm figuring the low temp would be caused by a stuck thermostat, it gets up to operating temp if I'm parked, but barely makes it over the 100 degree mark when I'm driving.

My question is would that cause the TPS code? The Jeep is running just fine?

Thanks for your help!

Not sure really. You could unplug it and spray it with some of that electronics cleaner. Maybe disconnect the battery to 'reboot' the PCM.
