No a canister purge valve will not cause this code, The switching valve job is to pump pressurize air into the exhaust port through the air switching valve , this is to warm up the catalytic convertor so it can control emission during cold start ups,There was at one time a emission warranty TSB number CAN-TSB2763. or EGO27-07 This is about the air injection controll driver being the cause the repair is covered under warranty at 36,000 mile to 50,000 miles
