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 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.





CONSULT REFERENCE VALUE IN DATA MONITOR MODE
- Specification data are reference values.





ECM TERMINALS AND REFERENCE VALUE

Remarks: Specification data are reference values, and are measured between each terminal and (25) (ECCS ground) with a voltmeter.





ON BOARD DIAGNOSIS LOGIC








OVERALL FUNCTION CHECK
This procedure can be used for checking 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 Generic Scan Tool
(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 Tool
(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.
