Lots of codes

Took my car to check why my traction light, check engine light were on, was told air injection system. I know if I take it to the dealer, it will cost me an arm and a leg. The codes were, P2444 secondary air injection pump stuck on bank 1, P2442 secondary air injection switching valve stuck open bank 2, P2441 switching valve stuck closed bank 2, P2440 switching valve stuck open bank 1, P2432 flow/pressure sensor circuit low bank 1, P2443 switching valve stuck closed bank 2, I know what parts they are, my problem is how hard is it to replace them.

 

Really? You're going to list the codes but not list the parts and make it easy to answer your query???

 

Check Hewitt technology for bypass

 

What parts exactly are you replacing? I'm having a similar issue and think that the secondary air injection pump will fix at least some of my problems. Not sure if it will fix all the problems though. We've got P2440, P2432. P0415, and P0419 going off as well as the TSC and 4x4 light blinking occasionally.
