HELP. Getting a constant P0412 but the AIR pump itself works fine? Did an engine swap, wondering if 2001 model cars had an AIR SOL relay in the underhood fuse box and where would it be located. I replaced everything but the AIR SOL relay (since the V8 donor car didn't have it, and I can't find where it would go?). I'm still getting only P0412.

I need the info for an 01. I have a 99 factory service manual and it says there is an AIR SOL relay which I cannot find at all on the 01 car. Thanks though!!

I just replaced the one part I hadn't replaced - the drivers side check valve - and it still throws P0412... Any ideas? Bueller? Bueller?

Just an update. We tracked the bad wire down using an electrical tester. One of the wires in the system was not receiving 12v power like it should have been. We jumped a wire from a hot wire on the AIR PUMP relay to the wire that should have been receiving power at all times, and once clearing the code the issue went away.

Do Work Son!
