The mystery of the missing MAF
#11
A missing AIR pump probably wouldn't cause those failures, besides, have you confirmed that anything is actually missing? It might just be unplugged. It would be more like a failure of a visual check for missing components done by the inspector. Your failures are probably due to other defects. I am sure other folks here can help with that better than I can.

As mentioned, the AIR pump only runs upon initial start up, it's to help warm up the cat converter faster. Once the engine is warmed up a little, the pump isn't running and has no effect on emissions. You might fail a visual inspection if they look under the hood, and know what the heck they're looking at, otherwise I wouldn't waste my money on a new pump. Here by me, they don't even pop the hood when doing the emissions test.
