INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE ENGINE COOLANT TEMPERATURE
SENSOR
(a) Disconnect the ECT sensor connector.
(b) Using a 19 mm deep socket wrench, remove the ECT
sensor and gasket.
3. INSPECT ENGINE COOLANT TEMPERATURE
SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: Refer to the chart graph
If the resistance is not as specified, replace the ECT sensor.
4. REINSTALL ENGINE COOLANT TEMPERATURE
SENSOR
(a) Using a 19 mm deep socket wrench, install the ECT sen-
sor and gasket.
Torque: 20 N·m (200 kgf·cm, 14 ft·lbf)
(b) Connect the ECT sensor connector.
