DTC 1005

EGRC-Solenoid Valve (DTC: 1005)




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




DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

OVERALL FUNCTION CHECK
Use this procedure to check the overall function of the EGRC-solenoid valve circuit.
During this check, a DTC might not be confirmed.

With Consult
1) Turn ignition switch "ON".




2) Perform "EGRC SOL/V CIRCUIT" in "FUNCTION TEST" mode with CONSULT.

OR

With Consult
1) Turn ignition switch "ON".




2) Perform "EGRC SOLENOID VALVE" in "ACTIVE TEST" mode with CONSULT and check the operating sound, according to ON/OFF switching.

OR

Without Scan Tools
1) Turn ignition switch "ON".
2) When disconnecting and reconnecting the EGRC-solenoid valve harness connector, make sure that the solenoid valve makes operating sound.
