DTC P1400: EGR Control Solenoid Valve: Description

The EGR Control (EGRC) solenoid valve responds to signals from the ECM. When the ECM sends an OFF signal, the vacuum signal passes through the solenoid valve. The signal then reaches the EGR valve. When the ECM sends an ON signal, a plunger will then move to cut the vacuum signal from the throttle body to the EGR valve.
