IN-VEHICLE SENSOR
Component DescriptionINFOID:0000000001547438
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 assem-
bly. It produces vacuum pressure due to air discharged from the A/C
unit, continuously taking compartment air in the aspirator.
In-Vehicle Sensor Diagnosis ProcedureINFOID:0000000001547439
DIAGNOSTIC PROCEDURE FOR IN-VEHICLE SENSOR
SYMPTOM: In-vehicle sensor circuit is open or shorted. (22 or
AUTO22 is indicated on front air control as a result of performing self-
diagnosis STEP-2.)

SUNLOAD SENSOR
SUNLOAD SENSOR
System DescriptionINFOID:0000000001547443
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor (1) is located on the instrument upper mask. It
detects sunload entering through windshield by means of a photo
diode. The sensor converts the sunload into a current value which is
then input into the front air control.
SUNLOAD INPUT PROCESS
The front air control also includes a processing circuit which averages the variations in detected sunload over
a period of time. This prevents drastic swings in the ATC system operation due to small or quick variations in
detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
Sunload Sensor Diagnosis ProcedureINFOID:0000000001547442
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted. (25 or AUTO25
