Got a P0410 code about "secondary air injection system fault". Car is 2001 Olds Intrigue. I did not know it had an "air pump". What does this do and where is it? I and an auto parts guy looked for it and could not find it. I did find the fuse and relay which seem to be OK. I would like to check the connector on the air pump but can't find the darn thing! Can you help?
The pump is on the left front subframe in the engine compartment. Check for a vacuum hose off or any hoses kinked or having holes in them. Also check the airduct for a holes as well. Any of those things will set a code. If no tthen a scanner has to lok at freeze frame data if there is any.
