ENGINE COOLANT TEMPERATURE SENSOR INSPECTION

PROCEDURE

  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR

    1. A287154C07

      *a

      Component without harness connected

      (Engine Coolant Temperature Sensor)

      *b

      Resistance (kΩ)

      *c

      Temperature (°C)

      *d

      Acceptable

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

      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 engine coolant temperature sensor in water, do not allow water to contact the terminals. After checking, dry the sensor.

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