Ambient Sensor Circuit
EJS0037G
COMPONENT DESCRIPTION
Ambient Sensor
The ambient sensor is attached on the radiator core upper support. It
detects ambient temperature and converts it into a resistance value
which is then input into the auto amplifier.
AMBIENT TEMPERATURE INPUT PROCESS
The automatic amplifier includes a processing circuit for the ambient sensor input. However, when the temper-
ature detected by the ambient sensor increases quickly, the processing circuit retards the auto amp. function.
It only allows the auto amp. to recognize an ambient temperature increase of 0.33
°
C (0.6
°
F) per 100 seconds.
As an example, consider stopping for a cup of coffee after high speed driving. Although the actual ambient
temperature has not changed, the temperature detected by the ambient sensor will increase. This is because
the heat from the engine compartment can radiate to the front grille area, location of the ambient sensor.
DIAGNOSTIC PROCEDURE FOR AMBIENT SENSOR
SYMPTOM: Ambient sensor circuit is open or shorted. (21 or

21 is
indicated on auto amp. As a result of conducting Self-diagnosis
STEP 2.)
1.
CHECK VOLTAGE BETWEEN AMBIENT SENSOR HARNESS CONNECTOR AND GROUND
Disconnect ambient sensor harness connector.
