Problem 2001 Dodge Intrepid 2.7L U eng. Didn't pass inspection because of O2 sensors. Replaced with new O2 sensors. reinspected. Now get code 0601 and 4 new codes that says O2 sensors not ready. Drove 70 miles before reinspection. Now they are telling me PCM is bad. I don't have any engine problems. Runs like it should, no missing, no knocks, no power loss. What do I do? I REALLY don't want to have the Dodge dealer replace my PCM and can do it myself but I really don't think it is the computer. The car runs to good. Oh yeah, the check engine light didn't come on till after the first inspection was over.

 

If the code changed, I doubt the PCM is bad. Could be wires to the sensors or bad sensor was installed.
