slangin' codes I noticed the other day my trans am SES light does not light up when key turns over, so I got curious and scanned it. I guess someone took the bulb out(idiots)
410
412
418
they are all "secondary air injection system malfunction" codes
Is this the AIR pump????

First step in the diagnosis charts for each of those codes is to check the AIR PUMP fuse for an open. Start there and replace the fuse if it's blown, if it blows again you'll have to look further.

Mine is throwin the same codes except P0410. Its only P0412 and P0418 but they always come on simultaneously. I checked the fuse and its ok..changed the relay, and the drivers side check valve but no luck. I've heard it's usually one of those three but it's not working for me. Anyone know of anything else it could be?
