- Measure the resistance.
- Using an ohmmeter, measure the resistance between the terminals.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 2.32 to 2.59 kΩ 1 - 2 80°C (176°F) 0.310 to 0.326 kΩ NOTE:When checking the engine coolant temperature sensor in water, keep the terminals dry. After checking, wipe the sensor dry.
If the resistance is not as specified, replace the engine coolant temperature sensor.
