Exhaust Gas RECIRCULATION (EGR) System, Overview: Notes
NOTE:
- The function/control of the Exhaust Gas Recirculation (EGR) system is managed by the Diesel direct injection system ECM -J248- via the EGR Vacuum Regulator solenoid valve -N18-.
- The cone-shaped plunger in the mechanical EGR valve ensures that various cross sectional openings are possible at different plunger heights.
- Every possible valve position is provided via pulsed control.
- Always replace self-locking nuts.
