Evaporator Temperature Sensor / Switch: Description and Operation

Intake Sensor / Automatic A/C
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 above.

If NG, replace intake sensor.
