Evaporator Temperature Sensor / Switch: Testing and Inspection

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.
