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 below.
