Using an ohmmeter, measure the resistance between the terminals.

  • Standard resistance:
  • TemperatureSpecified Condition
    Approx. 20°C (68°F)2.32 to 2.59 kΩ
    Approx. 80°C (176°F)0.310 to 0.326 kΩ
  • NOTICE:
  • While checking the engine coolant temperature sensor in water, be careful not to allow water to enter the terminals. After checking, wipe up water on the engine coolant temperature sensor.

If the result is not as specified, replace the sensor.
