  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR

    1. A331269C01

      *a

      Component without harness connected

      (Engine Coolant Temperature Sensor)

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      1 - 2

      20°C (68°F)

      6.245 to 6.407 kΩ

      80°C (176°F)

      0.629 to 0.636 kΩ
      Note:

      If checking the engine coolant temperature sensor in water, be careful not to allow water to contact the terminals. After checking, wipe the water off the engine coolant temperature sensor.

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