Creta Water Sensor Error

My 2019 Hyundai Creta diesel has 65053 km. The check engine light came on, and diagnostics say it's the water sensor. The engine is also running rough. Could it just be the sensor?

Summary of the thread

A 2019 Hyundai Creta diesel with 65,053 km had a check engine light indicating a water sensor error, accompanied by rough engine performance. The initial suspicion was a faulty sensor, but further investigation revealed a defective plug connector as the root cause. After replacing the connector, the vehicle's performance returned to normal.

Did this summary help you solve your problem?

Interesting. I also drive a Creta, and I had similar symptoms recently. The error memory was also full. Did you check the cable and plug connections to the sensor? Did you do any sensor testing?

I suspected a wiring issue and checked the connector visually, but didn't see anything obvious like corrosion or loose pins. Maybe I ruled it out too fast? What fixed your Creta? What should I look for when testing the moisture sensor?

My issue was a defective plug connector, like you first thought. I'd advise a workshop visit before it becomes a bigger problem. Auto electronics can be complex.

Thanks! You were right. The shop found a faulty connector on the water sensor. 95€ later, it's running smoothly.
