System Description

INFOID:0000000001547365

COMPONENT DESCRIPTION

Intake Sensor

The intake sensor (1) is located on the A/C unit. It converts tempera-
ture of air after it passes through the evaporator (2) into a resistance
value which is then input to the front air control.

Intake Sensor Diagnosis Procedure

INFOID:0000000001547366

DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR

SYMPTOM: Intake 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 INTAKE SENSOR AND GROUND

1.

Turn ignition switch OFF.

2.

Disconnect intake sensor connector.

3.

Turn ignition switch ON.

4.

Check voltage between intake sensor harness connector M92
terminal 1 and ground.

Is the inspection result normal

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK CIRCUIT CONTINUITY BETWEEN INTAKE SENSOR AND FRONT AIR CONTROL

2.

Go to self-diagnosis 

HAC-213, "Front Air Control Self-Diagnosis"

 and perform self-diagnosis.

NO

>> 1.

Replace intake sensor. Refer to XXXX

2.

Go to self-diagnosis 

HAC-213, "Front Air Control Self-Diagnosis"

 and perform self-diagnosis.

4.

CHECK CIRCUIT CONTINUITY BETWEEN INTAKE SENSOR AND FRONT AIR CONTROL

1.

Turn ignition switch OFF.

2.

Disconnect front air control connector.

3.

Check continuity between intake sensor harness connector M92
(A) terminal 1 and front air control harness connector M86 (B)
terminal 6.

4.

Check continuity between intake sensor harness connector M92
(A) terminal 1 and ground.

Is the inspection result normal

YES

>> 1.

Replace front air control. Refer to XXXX

2.

Go to self-diagnosis 

HAC-213, "Front Air Control Self-Diagnosis"

 and perform self-diagnosis.
