Evaporator Temperature Sensor / Switch: Description and Operation

Intake Sensor Circuit

COMPONENT DESCRIPTION







Intake Sensor
The intake sensor is located on the heater and cooling unit. It converts temperature of air after it passes through the evaporator into a resistance value which is then input to the air control.

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.
