Dean H Posted June 18, 2025 Report Share Posted June 18, 2025 (edited) Oops! I was thinking about another thread with overheating issues. The 2.4 engine does seem to experience head gasket failures.

John/Horace Posted June 20, 2025 Report Share Posted June 20, 2025 You need graphs to analyze trim, should be sign wave on upstream, both sides of volt set point. Downstream should be close to straight line. You aren’t getting one of several cat codes like efficiency etc, so ignore for now. Reluctor ring is what CPS sensor sees for timing firing. It’s behind crank pulley, can get worn and cause miss fires. Not a common problem, good scanner or physical examination I guess. It’s not a Dorman CPS sensor correct, NTK or Mopar. Try pulling it out again, make sure no dirt build up or old oring left in place. Sensor sits flat and snug. Quote Link to comment Share on other sites More sharing options...

andy1t Posted June 20, 2025 Report Share Posted June 20, 2025 hey... my tech friend found the prob...faulty ECM/PCM... Swapped it for one he had with him... reprogrammed it.. car ran great...just have to get a new/recon unit... so after changing all timing chains, sensors, plugs n coils... it turns out its the ECM... ah well... at least it got the timing chain done.. 167,000kms... Thank you so much for all your input and insights. John/Horace and Summer Solstice 2 Quote Link to comment Share on other sites More sharing options...
John/Horace Posted June 20, 2025 Report Share Posted June 20, 2025 Thanks for follow up posting. Daughter in laws 2012 with 2.4 had it turn out CPS (no codes to work with) just lucky I guess. ECM on most vehicles rarely ever go. Electronic throttle body is how ever a common 2.4 issue, but not 3.6. What scanner used for reprogramming, curious.

andy1t Posted June 20, 2025 Report Share Posted June 20, 2025 he thought it cd have been throttle body when he pressed gas pedal and got little response... so he swapped out ecm... after reprog ...started up ..instant response on gas pedal.. took it for a quick spin and it was off like a jack rabbit...so ECM was the prob. I think the scan tool was an XTOOL.. not sure of model... but it was about a 10 inch screen.... but like i said.. hes a retired Dodge tech and has all the good equipment.
