THE CODE P410 IS A 'GENERIC' GLOBAL CODE FOR SECONDARY A.I.R. SYSTEM MALFUNCTION - THE P2443 IS SUBARU SPECIFIC FOR S.A.C. VALVE (SECONDARY AIR COMBINATION VALVE) BANK #2 - THE VALVES ALLOW FRESH AIR INTO THE CONVERTER TO HELP WITH THE GAS CONVERSION - A SIGNAL WAS SENT TO THE PCM THAT THE VALVE WAS STUCK CLOSED WHEN A COMMAND FOR AIR FLOW OCCURED - IT COULD BE ANYTHING FROM A PINCHED HOSE TO A BAD VALVE TO A BLOWN FUSE. I HAVE ATTACHED A FLOW CHART TO HELP WITH THE DIAGNOSIS. THANKS, DAVE.
without the wiring diagram, these checks are impossible, where do i get the diagram? Is there anything a home mechanic can do or is the only option to go to a dealer for the tooling?
If so, how do I get them to follow this?
