>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE 

1. Turn ignition switch ON and wait at least 5 seconds.

2. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-329, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012197876

1.

CHECK TURBOCHARGER BOOST SENSOR POWER SUPPLY

1. Disconnect turbocharger boost sensor harness connector.

2. Turn ignition switch ON.

3. Check the voltage between turbocharger boost sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK SENSOR POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check harness connector for short to power and short to ground, between the following terminals.

DTC No.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK TURBOCHARGER BOOST SENSOR INPUT SIGNAL CIRCUIT

1. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.

2. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace error-detected parts.

5.

CHECK TURBOCHARGER BOOST SENSOR

Check the turbocharger boost sensor. Refer to 

EC-330, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace turbocharger boost sensor. Refer to 

EM-40, "Exploded View"

.

2. Remove turbocharger boost sensor with its harness connector.
3. Install pressure pump (A) to turbocharger boost sensor  .

CAUTION:

When insert a pressure pump hose to the sensor, be careful

to the damage of the sensor housing.

4. Turn ignition switch ON.

5. Check the voltage between ECM harness connector terminals

as per the following conditions.

NOTE:

• Always calibrate the pressure pump gauge when using it.

• Inspection should be done at room temperature [10 - 30

°C (50 - 86°F)].
