What Does a Coolant Temperature Sensor Do?

The engine coolant temperature sensor (ECT sensor or CTS) is a thermistor-based sensor that measures the temperature of the engine coolant circulating through the engine block and cylinder head. As coolant temperature changes, the sensor's electrical resistance changes proportionally, and the ECU reads this resistance to determine the precise coolant temperature. The ECU uses this data to control fuel injection quantity and timing (richer mixture when cold, leaner when warm), ignition timing advance, idle speed, cooling fan activation, and cold-start fuel enrichment. A faulty coolant temperature sensor can cause the ECU to receive incorrect temperature readings, leading to poor fuel economy, rough running, overheating, or failed emissions tests.

Installation Notes

Professional installation is recommended for best results. Coolant temperature sensor replacement requires allowing the engine to cool completely before starting work to avoid burns from hot coolant. Partially drain the cooling system to below the sensor level to minimise coolant loss. Disconnect the electrical connector, then carefully remove the sensor using the correct socket. Apply thread sealant to the new sensor threads if required. Install the new sensor and torque to manufacturer specifications — do not overtighten. Reconnect the electrical connector. Top up the cooling system with the correct coolant specification and bleed any air from the system. Clear any diagnostic trouble codes and test drive to verify correct temperature gauge operation and confirm no fault codes return.
