Evaporator Temperature Sensor / Switch: Testing and Inspection








AIR CONDITIONING: EVAPORATOR TEMPERATURE SENSOR:

INSPECTION

1. INSPECT EVAPORATOR TEMPERATURE SENSOR





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





- Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.

- When measuring, the sensor temperature must be almost 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 sensor.
