Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 Approx. 20°C (68°F) 2.32 to 2.59 kΩ Approx. 80°C (176°F) 0.310 to 0.326 kΩ TEXT IN ILLUSTRATION*1 Resistance *2 Temperature *3 Acceptable Range *a Component without harness connected
(Engine Coolant Temperature Sensor)NOTE:When checking the sensor in water, keep the terminals dry. After the check, wipe the sensor dry.
If the result is not as specified, replace the engine coolant temperature sensor.
- Partially soak the sensor in the water and warm up the water.
