ECT Sensor Resistance Inspection
- Drain the engine coolant. (See COOLING SYSTEM SERVICE WARNINGS [L3 WITH TC] .)
- Remove the ECT sensor (located above the starter).
- Place the ECT sensor in water with a thermometer, and heat the water gradually.
- Measure the resistance between the ECT sensor terminals A and B using a tester.
- If not as specified, replace the ECT sensor.
- If the ECT sensor is normal, but PID value is out of specification, perform the "CIRCUIT OPEN/SHORT INSPECTION ".
