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

INSPECTION

1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
(a) Disconnect the ECT sensor connector.





(b) Using SST, remove the ECT sensor and gasket. SST 09205-76030





3. INSPECT ECT SENSOR
Using an ohmmeter, measure the resistance between the terminals.

Resistance: Refer to chart graph

If the resistance is not as specified, replace the ECT sensor.

4. REINSTALL ECT SENSOR
(a) Install a new gasket to the ECT sensor.
(b) Using SST, install the ECT sensor. SST O9205-76030

Torque: 19.6 N.m (200 kgf.cm, 14 ft.lbf)

(c) Connect the ECT sensor connector.
5. REFILL WITH ENGINE COOLANT
