Mondeo Hybrid Transmission Issue
Summary of the thread
A 2021 Ford Mondeo Hybrid is experiencing transmission issues, with warning lights on and rough, noisy shifting. The error memory indicates a radiator oil pressure defect, possibly due to a faulty cable or plug. It is suggested that a defective connection related to the radiator oil pressure sensor could cause these symptoms, triggering emergency mode and shift problems. The recommended solution is to have a qualified technician diagnose and repair the issue, which was confirmed to be a corroded connector on the sensor.

Thanks for the quick reply! I haven't noticed the fan running constantly, and the coolant level seems okay. But where exactly is this oil pressure sensor located? Is it something I could check myself before taking it in?

Given your vehicle's hybrid system and the potential for high-voltage components, I would strongly advise against attempting a self-diagnosis or repair, even for checking the sensor's location. The risk of electrical shock or further damage is significant. The sensor's location will vary depending on the specific Mondeo hybrid configuration, and accessing it may require specialized tools and knowledge. A qualified technician can accurately diagnose the issue and safely repair or replace any faulty wiring or the sensor itself.

You're absolutely right. Best not to mess with it myself. Took it to the workshop, and you nailed it! Turned out to be a corroded connector on the sensor. New connector and labor came to 95€. Thanks for steering me in the right direction!

Good day. Based on the symptoms and the error code, a defective cable or plug connection related to the radiator oil pressure sensor is highly probable. The transmission relies on accurate temperature readings for optimal operation. A faulty sensor can trigger emergency mode, the indicator lights, and the shift abnormalities. Is the cooling fan running constantly, even when the engine is cold? Have you observed any coolant leaks or a drop in coolant level?
