Coolant Temperature Sensor/Switch (For Computer): Description and Operation
Engine Coolant Temperature Sensor
MAT & CTS Sensor Characteristics
PURPOSE
Measures engine temperature and sends a voltage signal to the ECM.
LOCATION
At the side of intake manifold
OPERATION
This sensor measures the temperature of the engine coolant and converts its change into a resistance through a thermistor. That is, as coolant
temperature lowers, resistance increases and as it rises, resistance decreases. The ECM reads the resistance of the ECT sensor, and uses the
information to control outputs.
