  1. Remove the A/C room temperature sensor.

  1. Disconnect the connector from the A/C room temperature sensor.

  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
    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:
    1. Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
    1. When measuring, the sensor temperature must be the same as the ambient temperature.
    HINT:
    As the temperature increases, the resistance decreases (see the graph).
