NOTE: Perform the following inspection only when directed.
Resistance Inspection
1. Remove the ECT sensor.
2. Place the ECT sensor in water with a thermometer. and heat the water gradually.
Measure The ECT Sensor Resistance
3. Measure the resistance between ECT sensor terminals A and B using an ohmmeter.
-
If the ECT sensor is okay, but the PID value is out of specification, perform the "Circuit Open Short Inspection".
-
If not as specified, replace the ECT sensor.
