Ambient Sensor
Ambient Sensor Circuit
AMBIENT TEMPERATURE INPUT PROCESS
The A/C auto amp. equips a processing circuit for the ambient sensor input. However, when the temperature detected by the ambient sensor increases quickly, the processing circuit retards the A/C auto amp. function. It only allows the A/C auto amp. to recognize an ambient temperature increase of 0.33C (0.6F) per 100 seconds.
As an example, consider stopping for a few minutes after high-speed driving. Although the actual ambient temperature has not changed, the temperature detected by the ambient sensor increases. This is because the heat from the engine compartment can radiate to the front bumper area, the location of the ambient sensor.

NOTE:
Diagnosis Procedure
1.CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND
1 - Ground: Approx. 5V
2.CHECK CONTINUITY BETWEEN AMBIENT SENSOR AND A/C AUTO AMP.
2 - 37: Continuity should exist.
3.CHECK AMBIENT SENSOR
Check ambient sensor.
4.CHECK CONTINUITY BETWEEN AMBIENT SENSOR AND A/C AUTO AMP.
1 - 35: Continuity should exist.
1 - Ground: Continuity should not exist.

P0462, P0463 fuel level sensor
Description
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and transmits a signal to the
combination meter. The combination
meter sends the fuel level sensor signal to the ECM via the CAN communication
line.
It consists o ...
