Focus water sensor fault

Sounds familiar! I had something like that with my Focus, though I can't remember the exact mileage. It was also a sensor issue that made the car undriveable. Did you already check the car diagnostics?

Car diagnostics are already checked, and the error clearly points to the water sensor. However, I'm unsure if it's really the sensor itself or just the wiring. What exactly was the problem in your case?

Ah, okay. If the car diagnostics show the sensor and not the wiring, then changing the sensor might fix your problem. To be honest I don't know what it was exactly, but the workshop replaced a sensor, and it's been running fine since then. I would suggest going to the workshop!

Thank you for your advice. It was indeed the water sensor cable, causing an electrical fault. The repair cost was 95€. Appreciate your help!
