Evaporator Temperature Sensor / Switch: Testing and Inspection
COMPONENT DESCRIPTIONIntake Sensor
The intake sensor is located on the cooling unit. It converts temperature of air after it passes through the evaporator into a resistance value which is then input to the auto amp.
After disconnecting intake sensor harness connector, measure resistance between terminals 1 and 2 at sensor harness side, using the table.
If NG, replace intake sensor.
