Corolla water sensor issue

I had a similar issue with my Corolla. The check engine light and rough running were definitely worrying. Have you checked the sensor connections yourself? Sometimes it's just a loose plug.

Thanks! Could you tell me which sensor connections you mean? Also, did the error code point right to the water sensor, or was it a general code?

Yes, the error code pointed directly to the water sensor. I would recommend checking the connection and eventually going to the workshop, just in case. They will test the sensor properly.

Thanks for the advice! I had the sensor connections checked at a local workshop. The cable to the sensor was bad. Replacement and labor cost 95€. The check engine light is off, and the engine is running smoothly now. Thanks again!
