TAMIR Posted January 3, 2023 Report Share Posted January 3, 2023 I am facing and issue with my 2008 Dodge Journey 2.4 Engine (87000 miles) It all started with the traction control and check engine lights suddenly coming on during a regular drive, making my car stall. A quick scan displayed code nr. p0335 - cranck sensor - so replaced my cranck sensor (Genuine Mopar part). After replacing it, I drived for about 20 miles with no issues. The next morning, while starting my car, I suddenly had a rough 3-4 seconds start with again traction control and check engine lights coming on. I've reseted the code, and continued to drive with no problems for another 25 miles. Next morning, same scenario, but now after a short drive I had my car stalling again. I drove to my mechanic for a diagnostic check, and during his check he found misfires in cylinders 1 and 4. We ried to change between the coils, spark plugs (which are relatively new ones) and even the injectors to see whether the misfire will move to another cylinder, but it persisted and stayed in cylinders 1 and 4. According to the scanner, misfires were counted when starting the vehicle, no misfires when the engine is in idle, but when you hold the gas (basically whenever engine is above 1000 rpm), misfires jump up, and when the count in scanner gets to 200, cylinders 1 and 4 shut down, engine forges and engine light blinks. Shutting down and restarting the engine restarts the issue (check engine light stays on), and misfire count starts again from zero. We tried to locate any gasket leaks, clogging in the exhaust system and compression issues, but no issues found. Following all diagnostics, my mechanic suspects this is due to a failing cranckshaft reluctor wheel, but he is no quite sure about that. I would greatly appreciate it if someone could share from similar experience and provide some guidance about what else could cause this and possible solutions.

luzmina Posted January 3, 2023 Report Share Posted January 3, 2023 (edited) Check the crank sensor wiring, look for isolation damaged and pinching, if you have the Micropod 2 you can see real time data and that will help you. Do you have any more codes stored on the ECM? Are you using the copper OEM like spark plugs? Edited January 3, 2023 by luzmina Quote Link to comment Share on other sites More sharing options...

John/Horace Posted January 4, 2023 Report Share Posted January 4, 2023 (edited) Great links from Alldata. Even bad fuel can cause an issue like this, syphoning fuel can be a pain. Compare resistance values of the old and new CPS sensors. Failure Modes A failed crankshaft position sensor or code indicating that the signal does not correlate with the other engine position sensors, can be both mechanical and electrical. The mechanical problems can relate to the condition of the teeth on the reluctor ring. If a tooth is missing, it changes the signal. If the ring has shifted position on the crankshaft, the signal will not correspond with the camshaft position sensor. The other mechanical issue could be the fault of the timing chain. If the chain has stretched, the signals will not match and the engine management system will set a code.
