- INSPECT ENGINE COOLANT TEMPERATURE SENSOR
- Using an ohmmeter, measure the resistance between the terminals.
Standard resistance
RESISTANCE CHARTCondition Specified Condition 20°C (68°F) 2.32 to 2.59 kΩ 80°C (176°F) 0.310 to 0.326 kΩ Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
If the result is not as specified, replace the sensor.
NOTE: In case of checking the water temperature sensor in water, do not allow water to go into the terminals. After checking, dry the sensor.
