EGR Vacuum Regulator Solenoid: Description and Operation

EGR Vacuum Regulator (EVR) Solenoid

PURPOSE

The EGR Vacuum Regulator (EVR) solenoid is an electromagnetic device which controls vacuum output to the EGR valve.

OPERATION

The Powertrain Control Module (PCM) outputs a duty cycle to the EVR which regulates the vacuum level to the EGR valve.  As the duty cycle is
increased, so is the vacuum signal to the EGR valve.  The vacuum source is manifold vacuum.
