Coolant Temperature Sensor/Switch (For Computer): Description and Operation

Engine Coolant Temperature (ECT) sensor

PURPOSE

By measuring the amount of resistance at the sensor, the ECU can adjust the length of injector opening time required by the engine.

LOCATION

Right side of engine, below distributor assembly.

OPERATION

As water temperature increases, sensor resistance decreases. The ECU receives sensor information as resistance to ground.  Water temperature
information is used to determine proper fuel delivery.
