INSPECTION

PROCEDURE

1. INSPECT NO. 2 AIR CONDITIONING THERMISTOR ASSEMBLY

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Click Location & Routing(A52) Click Connector(A52) Tester Connection Condition Specified Condition Result A52-1(TMP2) - A52-2(-) 10°C (50°F) 3.87 to 3.96 kΩ kΩ A52-1(TMP2) - A52-2(-) 15°C (59°F) 3.15 to 3.23 kΩ kΩ A52-1(TMP2) - A52-2(-) 20°C (68°F) 2.57 to 2.66 kΩ kΩ A52-1(TMP2) - A52-2(-) 25°C (77°F) 2.12 to 2.20 kΩ kΩ A52-1(TMP2) - A52-2(-) 30°C (86°F) 1.75 to 1.83 kΩ kΩ A52-1(TMP2) - A52-2(-) 35°C (95°F) 1.46 to 1.53 kΩ kΩ A52-1(TMP2) - A52-2(-) 40°C (104°F) 1.22 to 1.29 kΩ kΩ A52-1(TMP2) - A52-2(-) 45°C (113°F) 1.03 to 1.09 kΩ kΩ A52-1(TMP2) - A52-2(-) 50°C (122°F) 0.87 to 0.92 kΩ kΩ A52-1(TMP2) - A52-2(-) 55°C (131°F) 0.74 to 0.78 kΩ kΩ A52-1(TMP2) - A52-2(-) 60°C (140°F) 0.63 to 0.67 kΩ kΩ NOTICE: Hold the sensor only by its connector. Touching the sensing portion 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 result is not as specified, replace the No. 2 air conditioning thermistor assembly.
