Regarding Wiring Diagram information, Manual Air Conditioner.

DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR





SYMPTOM: Intake sensor circuit is open or shorted.
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 M146 terminal 2 and ground.

2 - Ground : Approx. 5V

Is the inspection result normal?
YES - GO TO 2.
NO - 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
M146 (A) terminal 1 and front air control harness connector M52
(B) terminal 13.

1 - 13 : Continuity should exist.

Is the inspection result normal?
YES - GO TO 3.
NO - Repair harness or connector.
3.CHECK INTAKE SENSOR
Intake Sensor Component Inspection.
Is the inspection result normal?
YES - Replace front air control. Service and Repair.
NO - Replace intake sensor. Intake Sensor.
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
M146 (B) terminal 2 and front air control harness connector M52
(A) terminal 12.

2 - 12 : Continuity should exist.

4. Check continuity between intake sensor harness connector
M146 (A) terminal 2 and ground.

2 - Ground : Continuity should not exist.

Is the inspection result normal?
YES - Replace front air control. Service and Repair.
NO - Repair harness or connector.
