are these codes important???
I pulled codes, and I think I got...
44 Thermactor Air Injection system inoperative (Right side).
and
52 Power steering pressure switch always open or closed
I dont know how to troubleshoot either of these problems... Or what they really mean.... I know that the Thermactor pump is your smog pump... but IM not sure what could cause it to fault out... I replaced the EGR and the codes still there...
I dont know much about the power steering... its seems like a fairly simple system... and I have no idea where the "Switch" would be. and I have a feeling its some type of electrical circuit and not a real switch...
Any help would be appreciated.

That is important because it supplies oxygen to your cats in the exhaust, and w/o that oxygen those cats will fail.

On my truck, that vacuum line goes to a valve located just at the outlet of the smog pump. Basically directly below where you are holding the line in the picture. There should be a nipple on top of the valve for the vacuum line.
