Evaporator Temperature Sensor / Switch: Testing and Inspection

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

1. INSPECT A/C EVAPORATOR TEMPERATURE SENSOR

(a) Remove the A/C evaporator temperature sensor (A/C thermistor).

(b) Disconnect the connector from the A/C evaporator temperature sensor (A/C thermistor).





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





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 value is not as specified, replace the sensor.
