PERFORM DIAGNOSIS PROCEDURE

NOTE:
DTC P1453 can not duplicate.

>> Proceed to 

EC-1094, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010935782

1.

VISUALLY CHECK

Visually check for chipping DPF (Diesel Particulate Filter) differential pressure sensor and turbocharger.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace malfunctioning parts.

2.

CHECK DPF DIFFERENTIAL PRESSURE SENSOR HARNESS CONNECTOR CONNECTIONS

Check DPF differential pressure sensor harness connector connection.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts.

3.

CHECK DPF DIFFERENTIAL PRESSURE SENSOR CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Check DPF differential pressure sensor circuit for open and short.

DTC No.

P1480 EXHAUST ELECTRIC THROTTLE CONTROL ACTUATOR

P1480 EXHAUST ELECTRIC THROTTLE CONTROL ACTUATOR

DTC Description

INFOID:0000000010935784

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Exhaust throttle valve stuck
• Exhaust electric throttle control actuator

FAIL-SAFE

CHECK DTC PRIORITY

If DTC P1480 is displayed with DTC P1481 or P1482, first perform the trouble diagnosis for DTC P1481 or
P1482.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-908, "DTC Index"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 1 minute before conducting the next test.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON and wait at least 5 seconds.

2.
