Tourneo check engine light water sensor error

Hi, I'm having a strange issue with my 2010 Ford Tourneo diesel. The check engine light comes on and the engine runs rough. I scanned it and found an error related to the water sensor. Mileage is at 142069 km. I've checked the sensor itself, but it looks fine. Could a faulty cable or plug connection to the component cause these symptoms?

I had a similar experience with my Tourneo, though it was a few years back. The check engine light and rough running are definitely concerning. Did the error code specifically point to the water sensor, or was it more generic? A bad connection is a very likely culprit, as these sensors are exposed to a lot of road grime and vibration.

Thanks for the quick reply! The error code specifically mentioned the water sensor. I'm not an expert, but could that code be triggered by a bad connection even if the sensor itself is working correctly?

Yes, absolutely. A bad connection can mimic a faulty sensor. Considering the error code and your symptoms, I'd strongly suspect the wiring or connector. I remember struggling with it myself. Eventually, I took mine to a workshop. They diagnosed it quickly with electrical fault tracing. It cost me 95€.

Thanks a lot for sharing your experience! It sounds like I should focus on checking the wiring and connector more thoroughly. If I can't find anything obvious, I'll take it to a workshop for professional diagnostics, as you suggested. Appreciate the help!
