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

1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
3. INSPECT ECT SENSOR RESISTANCE
- Using an ohmmeter, measure the resistance between the terminals.

Resistance: Refer to the graph

- If the resistance is not as specified, replace the sensor.
4. REINSTALL ECT SENSOR
- Install a new gasket to the ECT sensor.

Torque: 25 N.m (250 kgf.cm, 18 ft.lbf)

5. FILL WITH ENGINE COOLANT
