Bad Coolant Temperature Sensor Symptoms

A coolant temperature sensor is a device that monitors the coolant temperature in a car or other engine-powered vehicle. When the coolant reaches a certain temperature, the sensor will activate an indicator light or warning sound to let the driver know. If the coolant falls below that temperature, it can cause damage to engine parts.

A bad coolant temperature sensor can cause a car to overheat and potentially catch on fire. The sensor measures the coolant’s temperature and alerts the car’s computer when it reaches a certain threshold. If the sensor is not working properly, the computer will not be alerted and the car may overheat, leading to potential safety hazards.
