Safrane water sensor issue

I'm experiencing a strange issue with my 1999 Renault Safrane diesel. The check engine light illuminates, and the diagnostic tool reveals a water sensor error. The engine also runs roughly. I suspect a defective cable or plug connection. Any thoughts or similar experiences?

A 1999 Renault Safrane diesel exhibited a check engine light and rough engine performance, with diagnostics indicating a water sensor error. The issue was suspected to be a defective cable or plug connection. Advice was given to inspect the wiring harness near the sensor for corrosion or damage and to clean the contacts. Ultimately, the problem was resolved by replacing the faulty connection at the water sensor, resulting in smooth engine operation and the elimination of the check engine light.

Did this summary help you solve your problem?

I also have a Safrane, though I can't remember the year, and I had a similar thing happen a while back. The symptoms you described match my experience almost exactly. Have you checked the wiring harness near the sensor for corrosion or damage? Maybe try cleaning the contacts with some electrical contact cleaner?

Thanks for the tip! Which particular wiring harness are you referring to? The one directly connected to the sensor, or a more central one within the engine bay?

Ah, yes. It was the one directly connected to the sensor. After checking it all it was clear to me that I do not know how to fix it. You should just go to the workshop, it will save you the hassle, and it is usually not too expensive.

Took your advice and brought it in. Turns out it was indeed a faulty connection at the water sensor, as suspected. The cable and plug were replaced, costing around 95€. Engine runs smoothly now, and the check engine light is gone. Thanks again for pointing me in the right direction!
