BACKGROUND
*NOTE:
Because of a class action settlement, the warranty extension coverage for the EGR valve on 2002 MDXs purchased or leased between April 13,
2002, and November 7, 2006, is 8 years or 84,000 miles, whichever occurs first. For more information, refer to Service Bulletin 06-050, Warranty
Extension: Vehicle Warranty Mileage.*
In some 2001-02 MDXs, the EGR valve can become contaminated. If this happens, the vehicle may hesitate or surge during light acceleration, and the
MIL (malfunction indicator lamp) may come on with DTC P1491 (EGR valve insufficient lift).
Because of this possible problem, the EGR valve warranty is being extended to 8 years or 80,000 miles, whichever occurs first. For a vehicle to be
eligible, the EGR valve malfunction must be confirmed with the inspection procedure in this bulletin.
CUSTOMER NOTIFICATION
Owners of affected vehicles were mailed a letter about the EGR 8/80 warranty extension. An example of the letter is at the end of this service bulletin.
CORRECTIVE ACTION
Test-drive the vehicle with the HDS connected to check the EGR valve. If needed, replace the valve, and clear any stored DTCs.
