Model Years Affected: 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006

Exhaust & Emissions Affected: Gasoline

Average Mileage: 143,037 mi (134,111 mi - 150,000 mi)


One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
