AMBIENT SENSOR

Component Description

INFOID:0000000001547357

COMPONENT DESCRIPTION

Ambient Sensor

The ambient sensor is attached on the radiator core support upper. 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 the ambient sensor input. However, when the tempera-
ture detected by the ambient sensor increases quickly, the processing circuit retards the front air control func-
tion. It only allows the front air control to recognize an ambient temperature increase of 0.33

°

C (0.6

°

F) per 100

seconds.
As an example, consider stopping for a few minutes after high speed driving. Although the actual ambient tem-
perature 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.

Ambient Sensor Diagnosis Procedure

INFOID:0000000001547358

DIAGNOSTIC PROCEDURE FOR AMBIENT SENSOR

SYMPTOM: Ambient sensor circuit is open or shorted.
LEDs of intake switch (FRE, REC) does not illuminate as a result of
performing self-diagnosis STEP-2.

1.

CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND

1.

Turn ignition switch OFF.

2.

Disconnect ambient sensor connector.

3.

Turn ignition switch ON.

4.

Check voltage between ambient sensor harness connector E60
terminal 2 and ground.

Is the inspection result normal

YES

>> GO TO 2.

IN-VEHICLE SENSOR

Component Description

INFOID:0000000001547360

COMPONENT DESCRIPTION

In-vehicle Sensor

The in-vehicle sensor (1) is located on instrument lower finisher. It
converts variations in temperature of compartment air drawn from
the aspirator into a resistance value. It is then input into the front air
control.

Aspirator

The aspirator (1) is located on passenger’s side of A/C unit. It pro-
duces vacuum pressure due to air discharged from the A/C unit,
continuously taking compartment air in the aspirator.

In-Vehicle Sensor Diagnosis Procedure

INFOID:0000000001547361

DIAGNOSTIC PROCEDURE FOR IN-VEHICLE SENSOR

SYMPTOM: In-vehicle sensor circuit is open or shorted.
LEDs of intake switch (FRE, REC) does not illuminate as a result of
performing self-diagnosis STEP-2.
