Engine Temperature Sensor: Testing and Inspection

1NZ-FE ENGINE CONTROL SYSTEM: ENGINE COOLANT TEMPERATURE SENSOR: INSPECTION

INSPECTION





1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR
(a) Check the resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance:





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

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