2.CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND FRONT AIR CONTROL
1. Turn ignition switch OFF.
2. Disconnect front air control connector and sunload sensor con-
nector.
3. Check continuity between sunload sensor harness connector
M63 terminal 3 and front air control harness connector M60 ter-
minal 13.
4. Check continuity between sunload sensor harness connector
M63 terminal 3 and ground.
OK or NG
OK >> Replace sunload sensor.
NG >> Repair harness or connector.3 - 13 : Continuity should exist.
3 - Ground : Continuity should not exist.

TROUBLE DIAGNOSIS
Intake Sensor Circuit
EJS006BZ
COMPONENT DESCRIPTION
Intake Sensor
The intake sensor is located on the heater & cooling unit. It converts
temperature of air after it passes through the evaporator into a resis-
tance value which is then input to the front air control.
DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR
SYMPTOM: Intake sensor circuit is open or shorted. (56 or 57 is indi-
cated on front air control as a result of conducting Self-diagnosis.)
1.CHECK VOLTAGE BETWEEN INTAKE SENSOR AND GROUND
1. Disconnect intake sensor connector.
2. Turn ignition switch ON.
3. Check voltage between intake sensor harness connector M82
terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> GO TO 4.
2.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 M82
terminal 1 and front air control harness connector M60 terminal
13.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.

Refer toAT C - 11 5 , "
Intake Sensor".
OK or NG
OK >> 1. Replace front air control.
2. Go to self-diagnosisAT C - 5 5 , "
A/C System Self-diagnosis Function"and perform self-diagno-
sis.
NG >> 1. Replace intake sensor.
2. Go to self-diagnosisAT C - 5 5 , "
A/C System Self-diagnosis Function"and perform self-diagno-
sis.
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 M82
terminal 2 and front air control harness connector M60 terminal
12.
4. Check continuity between intake sensor harness connector M82
terminal 2 and ground.
OK or NG
OK >> 1. Replace front air control.
2. Go to self-diagnosisAT C - 5 5 , "
A/C System Self-diagnosis Function"and perform self-diagno-
sis.
NG >> Repair harness or connector.
COMPONENT INSPECTION
Intake Sensor
After disconnecting intake sensor connector, measure resistance
between sensor terminals 1 and 2, using the table below.
If NG, replace intake sensor.2 - 12 : Continuity should exist.
2 - Ground : Continuity should not exist.
