Bad Coolant Temp Sensor: Symptoms and Replacement Costs ...

2021-05-13· A bad coolant temp sensor can cause the engine temperature readings to be either too high or too low. In the first case, the engine temperature might actually be too cool or just right, but the sensor tells the ECU the engine is overheating. You’ll see this reflected in the dashboard temperature gauge. In the second case, the engine might actually be too hot and overheating. If the sensor is ...
