Stupid Jeep!!

Hey All…

Well after two years I finally got a new ECM for the TJ to take care of that whole O2 sensor problem I was having. I installed it tonight, start it up and within 30 seconds Bam! check engine light comes on with a new code… WTF!! :angry:

New code: P0463 “fuel tank level sensor circuit high input”

I have been having problems with the fuel gauge intermittently working lately.

Any thoughts?

Typical jeep, fix one problem another one shows up!.. lol

You need to find where the fuel sender grounds and refresh the ground. Also i would look for an underlying issue because although the code you got shows up in my experience it usually does not activate the MIL.
