Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: ON-VEHICLE INSPECTION

1. INSPECT EVAPORATOR TEMPERATURE SENSOR

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





Standard resistance:





NOTICE:
* 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 the same as the ambient temperature.

HINT
As the temperature increases, the resistance decreases (see the graph).

If the resistance is not as specified, replace the evaporator temperature sensor.
