Can anyone with a scanner and a 98-01 xj verify something for me?
Howdy everyone. Just wondering if anyone out there with a 98-01 (97 definitely has a different TCM) and a scanner that can communicate with the TCM can verify something for me. I bought a Jeep for my daughter and have been fixing some bugs. I came across something odd. If I check the TPS through the PCM it is showing 4V WOT and 100 percent throttle position. Now if I go to the TCM and check it shows 14v and around 200 percent throttle position. I verified the signal at the TCM connector and it is in fact only getting the 4 volts to it as it should. The leads me to believe that I possibly have an issue with the TCM. Or wondering if Chrysler might have just done something crazy with the programming to make us beat our heads against a wall even more than we already do. I was just curious if anyone with the ability could tell me what theirs reads. I ran these test KOEO. Thanks for any assistance you can provide me.
