P1400

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
Specification data are reference values and are measured between each terminal and (43) (ECCS ground).





ON BOARD DIAGNOSIS LOGIC

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

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.
(3) Start engine and warm it up to normal operating temperature.
(4) Maintain the following conditions for at least 5 consecutive seconds.
CMPS.RPM (REF): 1,000 - 3,000 rpm
B/FUEL SCHDL: 1.75 - 4 ms
VHCL SPEED SE: 10 km/h (6 MPH) or more

OR

OVERALL FUNCTION CHECK
Use this procedure to check the overall function of the EGRC-solenoid valve circuit. During this check, a 1st trip DTC might not be confirmed.





Without Consult
(1) Turn ignition switch "ON".
(2) Check operating sound of the solenoid valve when disconnecting and reconnecting harness connector.
