Re:code 12 egr valve HELP!!!
 

the egr valve is supposed to recurculate exhaust has back into the intake e.g.r ( Exhaust Gas Recurculation Valve)

Re:code 12 egr valve HELP!!!
 

The passage that goes to the egr isn't on the exhaust manifold...its in the head. Theres a small port in the actual runners that re-routes the gases. When i first put on the s-afc i got a CEL immediately but never checked what it was...i guess it was the egr now. I sold the s-afc and made my own widebanded basemap in uberdata for the f22a's. Send me a p06 and $55 and i'll chip it and send it back...add about $20-30 for datalogging if u want it
