Hello all, I was hoping to get some advice on my new to me 500 1.4 multiair. I'm getting a persistent p0342 code. I've replaced the cam position sensor, verified 5 volts at pin 3 of the connector, verified continuity from the CPS connector pins to the ECU pins, done the cam relearn using multiecuscan and an obdlink cable, and verified the timing is correct using the special timing belt tools. It is hard to start sometimes but once started runs pretty good. Any ideas?
 
Well, despite the lack of replies I want to update this thread for anyone else looking in the future. I may have figured out what is causing the persistent p0342 code. Attached is a photo of the new and old cam shaft. Same part numbers on both parts but somehow the timing tone wheel section has been rotated out of phase. I’m waiting on more parts in the mail so I will post when I’ve affirmatively fixed it. For now, I would say this is the most likely culprit.
