EGR Vacuum Regulator

The EGR Vacuum Regulator (EVR) is a solenoid valve which controls vacuum output to EGR valve. The EVR replaces the EGR solenoid vacuum vent valve assembly. When EVR is energized, the vent closes and increases the vacuum level. As EVR duty cycle is increased, an increased vacuum signal goes to the EGR valve.
