C5 Oil Temperature Sensor Fault

Anyone seen a weird warning light, error code, and oil pressure light issue on a 2020 Citroen C5 hybrid with 173013 km? Suspect it's the engine oil temp sensor cable or plug.

Whoa, that sounds familiar! I had almost the same issue with my C5. Is the oil gauge acting erratically too?

Could you elaborate on the specifics of the issue you encountered? I'm interested to know if your symptoms were identical, and what diagnostic procedures you used to find the fault.

Yep, the oil gauge was all over the place! I'd suggest getting it checked out by a workshop ASAP.

I had the vehicle inspected by a qualified technician, as you recommended. The diagnosis confirmed a faulty engine oil temperature sensor, specifically a defective connection as initially suspected. The repair, including parts and labor, amounted to 95€. Thanks again for your assistance.
