ENGINE COOLANT TEMPERATURE SENSOR INSPECTION


  1. INSPECT E.F.I. ENGINE COOLANT TEMPERATURE SENSOR


    1. Check the resistance.

      A01BFSCE04

      1. Using an ohmmeter, measure the resistance between the terminals.

        Standard resistance
        Tester connection Specified Condition
        1 (E2) - 2 (THW) 2.32 to 2.59 kΩ at 20 °C (68 °F)
        1 (E2) - 2 (THW) 0.310 to 0.326 kΩ at 80 °C (176 °F)

        Note

        If checking the engine coolant temperature sensor in water, be careful not to allow water to intrude into the terminals. After checking, clean off water on the engine coolant temperature sensor.

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