Prius Temperature Sensor Issues

Thanks for the insight. I haven't done in-depth sensor diagnostics, just a visual inspection of the wiring. Can you elaborate on the specific tests you ran? I want to understand how to check the sensor's output and whether any specific values would indicate a malfunction before I consider a vehicle temperature sensor replacement.

Given the complexity of the hybrid system and the potential for further issues, I would suggest a visit to a qualified workshop. While DIY diagnostics are possible, incorrect handling could exacerbate the problem. A professional diagnosis will pinpoint the exact cause, and they can accurately determine if it's the sensor itself or the wiring harness causing the fault.

I appreciate your advice. It seems the best course of action is to get it checked professionally. The repair ended up costing 95€, and you were correct, the problem was a defective cable to the temperature sensor.

I had a similar issue with my Prius. The symptoms you describe are very similar. In my case, the vehicle temperature gauge was also affected. Have you checked the wiring harness near the sensor? A damaged wire or corroded connector could indeed be the culprit. Also, have you tried running any sensor diagnostics to see if the sensor is providing any readings at all?
