Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: 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:





- 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 air conditioning harness (evaporator temperature sensor).
