ok, you probalby have a code P0410, and on this vehicle is usually the A.I.R. check valve on the back cylinder head. is this what you need instructions on?
Ok, I will post the instructions for the air pump check valve 90 percent of the time this will repiar the air pump, if you have a code P0411, if your not sure, might want to have the system scanned again, just to make sure what fault code is stored in the system.
Disconnect the engine wiring harness electrical connector from the AIR check valve.
