Temperature Sensor (Gauge): Description and Operation

ECT sensor and temperature gauge sender unit -up to 99MY
An Engine Coolant Temperature (ECT) sensor and a temperature gauge sender unit are located on the inlet manifold adjacent to the outlet pipe. The ECT sensor monitors coolant temperature emerging from the engine and sends signals relating to coolant temperature to the ECM for engine management. The temperature gauge sender unit operates the warning lamp and temperature gauge in the instrument pack.
