About Coolant Temperature Sensors

The coolant temperature sensor is important because it monitors the temperature of the coolant. It is crucial in making sure that the engine is performing at its best.

Coolant temperature sensor function

The coolant temperature sensor (CTS) in the vehicle is essential because it lets the control unit give warnings in case the engine is overheating. The device operates as the temperature changes and the possible difference output of the component changes as well. The temperature changes can be calculated by the engine's control unit.

In general, the coolant temperature is a thermistor because it influences its resistance in an inverse amount. There is constant monitoring of coolant resistance, the coolant temperature sensor transmits temperature data to the ECU.

Common issues with a failing coolant temperature sensor

A failing coolant temperature sensor can lead to an engine overheating, and trouble starting the vehicle.
