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. The vacuum signal passes through the solenoid valve. The signal then reaches the EGR valve. When the ECM sends an OFF signal, a plunger will then move to cut the vacuum signal from the throttle body to the EGR valve.

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

NOTE: 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-II and wait at least 5 seconds .
3. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

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" below.

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" below.

EGRC-solenoid valve







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

OR







Without Consult
If NG or operation takes more than 1 second, replace EGRC- solenoid valve.
