PROCEDURE

1. INSPECT AMBIENT TEMPERATURE SENSOR

(a) 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

1 - 2

15°C (59°F)

2.45 to 2.88 kΩ

1 - 2

20°C (68°F)

1.95 to 2.30 kΩ

1 - 2

25°C (77°F)

1.60 to 1.80 kΩ

1 - 2

30°C (86°F)

1.28 to 1.47 kΩ

1 - 2

35°C (95°F)

1.00 to 1.22 kΩ

1 - 2

40°C (104°F)

0.80 to 1.00 kΩ

1 - 2

45°C (113°F)

0.65 to 0.85 kΩ

1 - 2

50°C (122°F)

0.50 to 0.70 kΩ

1 - 2

55°C (131°F)

0.44 to 0.60 kΩ

1 - 2

60°C (140°F)

0.36 to 0.50 kΩ

NOTICE:

  • Hold the sensor only by its connector. Touching the sensor may change the resistance value.
  • When measuring, the sensor temperature must be the same as the ambient temperature.

HINT:

As the temperature increases, the resistance decreases (see the graph).

If the resistance is not as specified, replace the ambient temperature sensor.
