DTC Description

INFOID:0000000010935889

DTC DETECTION LOGIC

POSSIBLE CAUSE

ECM

FAIL-SAFE

• EGR valve is closed position
• Throttle control motor is opened
• Prohibit DPF regeneration

DTC CONFIRMATION PROCEDURE

1.

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 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON.

2.

Check DTC.

Is DTC detected?

YES

>> Proceed to 

EC-1183, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-1

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010935890

1.

CHECK ECM AIR INLET VISUALLY

Check if foreign matter is blocking the air inlet for ECM.

Is the inspection result normal?

YES

>> Replace ECM. Refer to 

EC-1226, "Removal and Installation"

.

NO

>> Remove foreign matter.

DTC No.

ATMOS PRESS SEN
(Barometric pressure sensor “A” circuit)
• 1.DEF: VOLTAGE TOO HIGH
• 2.DEF: VOLTAGE TOO LOW
• 3.DEF: IMPROPER SIGNAL SHAPE

• An excessively low voltage from the atmospheric pressure sensor (built-

into ECM) is sent to ECM. 

• An excessively high voltage from the atmospheric pressure sensor (built-

into ECM) is sent to ECM.
