P1400 Nissan Description

The EGRC-solenoid valve responds to signals from the Engine Control Module (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.
