AMBIENT TEMPERATURE SENSOR(for ZR Series Engine) INSPECTION

PROCEDURE

  1. INSPECT COOLER THERMISTOR (AMBIENT TEMPERATURE SENSOR)

    E354899E01

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      1 - 2

      10°C (50°F)

      3.00 to 3.73 kΩ

      15°C (59°F)

      2.45 to 2.88 kΩ

      20°C (68°F)

      1.95 to 2.30 kΩ

      25°C (77°F)

      1.60 to 1.80 kΩ

      30°C (86°F)

      1.28 to 1.47 kΩ

      35°C (95°F)

      1.00 to 1.22 kΩ

      40°C (104°F)

      0.80 to 1.00 kΩ

      45°C (113°F)

      0.65 to 0.85 kΩ

      50°C (122°F)

      0.50 to 0.70 kΩ

      55°C (131°F)

      0.44 to 0.60 kΩ

      60°C (140°F)

      0.36 to 0.50 kΩ
      Tip:

      As the temperature increases, the resistance decreases (refer to the graph).

      Note:

      • Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.

      • When measuring the resistance, the sensor temperature must be the same as the ambient temperature.

      If the result is not as specified, replace the cooler thermistor (ambient temperature sensor).
