Genesis Oil Level Sensor Fault

Greetings. The symptoms you've described strongly suggest a potential malfunction within the oil level sensing system. Given that you've already inspected the readily accessible wiring, it is plausible that the fault resides either within the sensor itself or deeper within the wiring harness. Have you by any chance used a multimeter to test the voltage and continuity of the wires leading to the sensor? Also, could you provide the specific error code that was retrieved during the diagnostic scan?

Thanks for the reply! I don't have a multimeter, and honestly, I wouldn't know how to use it properly. The error code was P2563 or something very similar – I didn’t write it down exactly. Does this mean I have to replace the whole sensor?

P2563 indicates a Turbine Speed Sensor 'A' Circuit Intermittent/Erratic/High. That is an error code that could mean that you should replace the whole sensor. Given your lack of experience with electrical testing, I would strongly advise against attempting a self-repair. The potential for misdiagnosis and further complications is significant. A reputable workshop possesses the necessary tools and expertise to accurately diagnose the root cause and implement the appropriate remedy. In my case, it turned out to be corrosion in the connector. They cleaned it, applied dielectric grease, and the problem disappeared. If you want to be on the safe side, visit the next workshop. Better safe than sorry!

Okay, thanks for the advice. I appreciate it! I took it to a local shop, and you were right. It was a corroded connector on the oil level sensor. They cleaned it up, and the error is gone. Total cost was 95€, which is way better than a new sensor!
