Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection

INSPECTION

1. DRAIN ENGINE COOLANT
2. REMOVE IGNITION COIL





3. REMOVE ECT SENSOR





4. INSPECT ECT SENSOR RESISTANCE
Using an ohmmeter, measure the resistance between terminals 1 (E2) and 2 (THW).

Resistance: Refer to the graph

If the resistance is not as specified, replace the ECT sensor.
5. REINSTALL ECT SENSOR
Install a new gasket to the ECT sensor.
6. FILL RADIATOR WITH ENGINE COOLANT
