Ambient Temperature Sensor / Switch HVAC: Testing and Inspection

COMPONENT INSPECTION

Ambient Sensor / Auto A/C:

Ambient Sensor
After disconnecting ambient sensor harness connector, measure resistance between terminals 2 and 1 at sensor harness side, using the table above.

If NG, replace ambient sensor.











AMBIENT SENSOR
The ambient sensor is attached to the radiator core support. It detects ambient temperature and converts it into a resistance value which is then input to A/C auto amp. and board computer. After disconnecting ambient sensor harness connector measure resistance between terminals 1 and 2 using the table.
