P1400

COMPONENT DESCRIPTION
The EGRC-solenoid valve (for California) or (except for California) EGR valve and EVAP canister purge control 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 EVAP canister and the EGR valve. When the ECM sends an OFF signal, the plunger is returned by the spring and cut the vacuum signal.

ON BOARD DIAGNOSIS LOGIC

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

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.
- Always perform the test at temperature of -10°C (14°F) or higher.




With Consult
1) Turn ignition switch "ON".
2) Select "DATA MONITOR" mode with CONSULT and wait at least 5 seconds.

OR

OVERALL FUNCTION CHECK
Use this procedure to check the overall function of the EGR valve and EVAP canister purge control solenoid valve circuit. During this check, a 1st trip DTC might not be confirmed.

With Generic Scan Tool
1) Turn ignition switch "ON" and wait at least 5 seconds.
2) Select "MODE 7" with GST.

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.
