Component Inspection (EGR Volume Control Valve)

INFOID:0000000012198490

1.

CHECK EGR VOLUME CONTROL VALVE-1

With CONSULT

1. Turn ignition switch ON and engine stopped.

2. On the CONSULT screen, select “ENGINE” >> “ACTIVE TEST” >> “EGR CONTROL VALVE”.

3. Operate “Up” or “Down”, set “EGR VALVE POSITION” to 0 deg, and check value of “EGR VALVE POSI-

TION SEN”.

Does value become 1.2

±0.15 V?

YES

>> GO TO 2.

NO

>> Replace EGR volume control valve. Refer to 

EM-239, "Removal and Installation"

.

2.

CHECK EGR VOLUME CONTROL VALVE-2

With CONSULT

1. Operate “Up” or “Down”, set “EGR VALVE POSITION” to 70 deg, and check value of “EGR VALVE POSI-

TION SEN”.

Does value become 4.0

±0.15 V?

YES

>> INSPECTION END

NO

>> Replace EGR volume control valve. Refer to 

EM-239, "Removal and Installation"

.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> 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-999, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012198492
