PROCEDURE


  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR


    1. Partially immerse the sensor in water and warm up the water.

      A01VLODE01

    2. Measure the resistance according to the value(s) in the table below.

      Text in Illustration
      *a

      Component without harness connected

      (Engine Coolant Temperature Sensor)
      *b Acceptable
      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Approximately 20°C (68°F) 2.32 to 2.59 kΩ
      Approximately 80°C (176°F) 0.310 to 0.326 kΩ

      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.
