DTC P1400 EGRC-SOLENOID VALVE

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 (from the intake manifold collector) 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 intake manifold collector to the EGR valve.

DTC Confirmation Procedure

NOTE: If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 5 seconds before conducting the next test.

WITH CONSULT-II
1. Start engine and warm it up to normal operating temperature.
2. Select DATA MONITOR mode with CONSULT-II.







3. Maintain the following conditions for at least 5 consecutive seconds.
4. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

WITH GST
- Follow the procedure with CONSULT-II.

Overall Function Check
Use this procedure to check the overall function of the EGR temperature sensor. During this check, a 1st trip DTC might not be confirmed.

WITHOUT CONSULT-II
1. Start engine and warm it up to normal operating temperature.




2. Check the voltage between ECM terminal 103 and ground at idle.
Voltage : 0 - 1V
3. Check that the voltage changes to battery voltage and returns to
0 - 1V when reviving the engine from idle to 3,000 rpm quickly.
4. If NG, go to "Diagnostic Procedure" below.
