DTC P1400 EGRC-SOLENOID VALVE

PFP:14956

Component Description

UBS00DO6

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 mani-
fold collector to the EGR valve.
