2AZ-FE ENGINE CONTROL: ENGINE COOLANT TEMPERATURE SENSOR: INSPECTION

1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR





(a) Measure the resistance.

(1) Using an ohmmeter, measure the resistance between the terminals.

Standard Resistance:





NOTICE:
When checking the engine coolant temperature sensor in water, keep the terminals dry. After checking, wipe the sensor dry.

(2) If the resistance is not as specified, replace the engine coolant temperature sensor.
