EGR System Controls and Purge Control



The controls associated with control of the EGR and purge control system are located within the control box on the firewall. These components include the EGR control solenoid valve, the CVC valve and air chamber if used, as well as the purge cut-off solenoid valve.

Replacement of any of these items requires removing the control box from its mounts, disconnecting the external electrical connectors and opening the control box. Disconnect the vacuum hose(s) to the component and remove the component. Installation is in the reverse order of removal.
