ENGINE COOLANT TEMPERATURE SENSOR INSPECTION

CAUTION / NOTICE / HINT

CAUTION:


  • B00251Z

    Do not your hands into the water that has been heated for the inspection.

  • Touching the heated water could result in burns.

PROCEDURE


  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR


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

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Approx. 20°C (68°F) 2.32 to 2.59 kΩ
      1 - 2 Approx. 80°C (176°F) 0.310 to 0.326 kΩ
      A01LC1SC14
      *a

      Component without harness connected

      (Engine Coolant Temperature Sensor)

      		 *b Resistance
      *c Temperature *d Acceptable Range

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

      Note

      When checking the engine coolant temperature sensor in water, keep the terminals dry. After the check, wipe the engine coolant temperature sensor dry.
