Ambient Sensor CircuitEJS006BW
COMPONENT DESCRIPTION
Ambient Sensor
Ambient sensor is attached to the radiator core support (left side). It
detects ambient temperature and converts it into a resistance value
which is then input into the front air control.
AMBIENT TEMPERATURE INPUT PROCESS
The front air control includes a processing circuit for ambient sensor input. However, when the temperature
detected by ambient sensor increases quickly, the processing circuit retards the front air control function. It
only allows the front air control to recognize an ambient temperature increase of 0.33°C(0.6°F) per 100 sec-
onds.
This prevents constant adjustments due to momentary conditions, such as stopping after high speed driving.
Although the actual ambient temperature has not changed, the temperature detected by ambient sensor will
increase. This is because the heat from the engine compartment can radiate to the front grille area, location of
ambient sensor .
DIAGNOSTIC PROCEDURE FOR AMBIENT SENSOR
SYMPTOM: Ambient sensor circuit is open or shorted. (40 or 41 is
indicated on front air control as a result of conducting the front air
control self-diagnosis)
1.CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND
1. Disconnect ambient sensor connector.
2. Turn ignition switch ON.
3. Check voltage between ambient sensor harness connector E48
terminal 4 and ground.
