Code 1005

COMPONENT DESCRIPTION
The EGRC-solenoid valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the coil in the solenoid valve is energized. A plunger will then move to flow the vacuum signal (from the intake manifold collector to the EGR valve.)
The vacuum signal passes through the solenoid valve. The signal then reaches the EGR valve. When the ECM sends an OFF signal, the plunger is returned by the spring and cut the vacuum signal.

TESTING CONDITION: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.





With Consult
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT and wait at least 5 seconds.
3. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tools
1. Turn ignition switch "ON" and wait at least 5 seconds.
2. Select "MODE 7" with GST
3. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

Without Scan Tools
1. Turn ignition switch "ON" and wait at least 5 seconds.
2. Turn ignition switch "OFF" and wait at least 5 seconds.
3. Turn ignition switch "ON" and perform "Diagnostic Test Mode (Self-diagnostic results)" with ECM.
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

DIAGNOSTIC PROCEDURE








With Consult
Check air passage continuity.
Perform "EGRC SOLENOID VALVE" in "ACTIVE TEST" mode.

OR








Without Consult
Check solenoid valve, following the table:
If NG or operation takes more than 1 second, replace the solenoid valve.
