REF: HEATING & AIR CONDITIONING
NO.: AC001-95
DATE: MAY 3, 1996
MODEL: LS 400, GS 300, SC 400, SC 300, ES 300
Title AMBIENT TEMPERATURE DISPLAYS -22°F
On Lexus models equipped with an ambient temperature display, -22°F may appear in the ambient temperature display if continuity through the ambient temperature sensor circuit is interrupted. Since the -22°F is retained in memory, the condition will persist even after continuity through the ambient temperature sensor circuit has been re-established. Climate control system operation may also be adversely affected.
This condition can be corrected by briefly removing the fuse supplying the B+ power source to the air conditioning control unit.
Do not attempt repairs before performing the following reset procedure:
Refer to the table and remove the appropriate fuse for 30 seconds and reinstall.
IMPORTANT :Some of these fuses provide power to other systems for memory retention. Check and reset clock, radio presets, and memory as necessary.
If ambient temperature display is not corrected, refer to repair manual for diagnosis.

The sensor is either located on the bumper reinforcement(big metal bar the bumper goes over), or located on the bar that goes from the upper to lower radiator support, Under the hood latch. make sure there arent any wires hangine loose not plugged in
