Crossfire Oil Sensor Failure Causing Multiple Warnings

As a Chrysler owner with some experience working on these models, I faced a similar issue with my 2006 Chrysler Sebring. The symptoms were almost identical, oil pressure warning lights, speedometer errors, and faulty sensor readings despite proper oil levels. After manual checks confirmed the engine oil was fine, my workshop diagnosed a faulty sensor connection. The oil monitoring system was giving false readings due to a damaged wire harness connecting to the oil detection sensor. The wiring had deteriorated over time, creating intermittent connection issues. The repair involved replacing the wiring connector and cleaning the sensor contacts. Total cost was 95€ for parts and labor. Since the fix, all warning lights cleared and the oil monitoring system has worked perfectly. Before suggesting this might be your exact issue, could you share: Current mileage on your Crossfire, When the warning lights first appeared, Whether the issues are constant or intermittent, Any recent car maintenance or oil changes, Whether the problem gets worse during wet weather This information would help determine if your symptoms match the wiring issue I experienced or point to a different sensor problem.

My Crossfire has 180233 KM on the clock, and I just had a full service last month. The original oil signal warnings started appearing intermittently, usually after cold starts. I had the engine oil manually checked multiple times, always showing correct levels, which points toward a sensor issue rather than an actual oil problem. Your experience with the wiring harness sounds very similar to what I am experiencing. The faulty sensor behavior matches exactly, especially the unusual warning signals despite proper oil levels. Did your repair shop need any special tools or diagnostic equipment for the oil detection system? Also, was it a straightforward fix once they identified the wiring as the problem? 95€ seems reasonable if it resolves all these warning lights. Will try to have my mechanic check the wiring connections to the sensor first before replacing any parts.

Thanks for the additional details about your Crossfire. Those symptoms definitely mirror what I experienced with my Sebring, particularly the cold start sensor warnings despite normal oil levels. The repair was straightforward once the wiring issue was pinpointed. My mechanic used basic diagnostic equipment to verify the oil detection system fault codes, but the actual fix mainly required standard tools to access and repair the wiring harness. One detail I should mention, after the initial repair, I had the workshop clean all the sensor contacts thoroughly with electrical contact cleaner. This extra step helped ensure reliable readings from the oil monitoring system going forward. The total repair time was under 2 hours. The oil gauge started working perfectly after the fix, and all error codes cleared from the system memory. While 95€ might vary by workshop, the wiring repair is generally more cost-effective than replacing the entire sensor unit. Since your mileage and symptoms match so closely with my experience, having your mechanic inspect the wiring harness connections first is a smart approach. The intermittent nature of your sensor issue strongly suggests an electrical connection problem rather than a failed sensor.

Thanks for sharing those detailed insights about your Sebring repair. Having the full picture of your repair process makes me feel more confident about tackling my Crossfire issues. The intermittent oil sensor warnings during cold starts really do seem identical to what you experienced. I will definitely have my mechanic focus on checking the wiring harness and cleaning all sensor contacts first. Good to know it only took about 2 hours for the complete fix, and that no specialized diagnostic tools were needed beyond basic car maintenance equipment. The oil monitoring system in these cars seems prone to wiring issues over time, but at least the fix appears straightforward. Will book an appointment to have the oil detection system and wiring checked next week. The repair cost around 95€ sounds much better than replacing sensors unnecessarily. Will update once I get the wiring harness and connections inspected. Hopefully cleaning the contacts and checking the electrical connections will resolve my faulty sensor readings just like in your case.
