AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: INSPECTION

INSPECTION

1. INSPECT FRONT EVAPORATOR TEMPERATURE SENSOR

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

Standard resistance:

NOTICE:
-

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

-

When measuring the resistance, the temperature of the sensor and the cooler thermistor must be the same.

HINT: As the temperature increases, the resistance decreases (see the graph).
If the operation is not as specified, replace the evaporator temperature sensor.
