What Does a Coolant Temperature Sensor Do?

The Coolant Temperature Sensor (CTS) monitors the temperature of the engine coolant and sends this information to the engine control unit (ECU). The ECU uses this data to adjust fuel injection, ignition timing, and cooling fan operation. When the engine is cold, the sensor signals the ECU to enrich the fuel mixture for easier starting and warm-up. As the engine reaches operating temperature, the sensor helps maintain optimal performance and fuel efficiency.
