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
