IN-VEHICLE SENSOR
Component Description
INFOID: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 Procedure
INFOID:0000000001547439
DIAGNOSTIC PROCEDURE FOR IN-VEHICLE SENSOR
SYMPTOM: In-vehicle sensor circuit is open or shorted. (22 or
AUTO
22 is indicated on front air control as a result of performing self-
diagnosis STEP-2.)

IN-VEHICLE SENSOR
1.
CHECK VOLTAGE BETWEEN IN-VEHICLE SENSOR AND GROUND
1.
Turn ignition switch OFF.
2.
Disconnect in-vehicle sensor connector M93.
3.
Turn ignition switch ON.
4.
Check voltage between in-vehicle sensor harness connector
M93 terminal 1 and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
CHECK CIRCUIT CONTINUITY BETWEEN IN-VEHICLE SENSOR AND FRONT AIR CONTROL
1.
Turn ignition switch OFF.
2.
Disconnect front air control connector M51.
3.
Check continuity between in-vehicle sensor harness connector
M93 (A) terminal 2 and front air control harness connector M51
(B) terminal 33.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair harness or connector.
3.
CHECK IN-VEHICLE SENSOR
HAC-135, "In-Vehicle Sensor Component Inspection"
.
Is the inspection result normal?
YES
>> 1.
Replace front air control. Refer to XX.
2.
HAC-98, "Front Air Control Self-Diagnosis"
STEP-2. Confirm that code No. 20 is displayed.
NO
>> 1.
Replace in-vehicle sensor. Refer to XX.
2.
HAC-98, "Front Air Control Self-Diagnosis"
STEP-2. Confirm that code No. 20 is displayed.
4.
CHECK CIRCUIT CONTINUITY BETWEEN IN-VEHICLE SENSOR AND FRONT AIR CONTROL
1.
Turn ignition switch OFF.
2.
Disconnect front air control connector M51.
3.
Check continuity between in-vehicle sensor harness connector
M93 (A) terminal 1 and front air control harness connector M51
(B) terminal 28.
4.
Check continuity between in-vehicle sensor harness connector
M93 (A) terminal 1 and ground.
