EGR Valve: Application and ID

EGR VALVE IDENTIFICATION
- The Electronic Exhaust Gas Recirculation (EGR) valve has a non-removeable, thick, black plastic top, which the part number is laser marked on.

- Port EGR valves have no identification stamped after the part number.

- Negative backpressure EGR valves will have an "N" stamped on the top side of the valve after the part number.

- Positive backpressure EGR valves will have a "P" stamped on the top side of the valve, after the part number.

- When replacing an EGR valve, always check for correct part number in the parts catalog or supplemental bulletin.
