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
