P0491 & P0492

[RAUDIS6]

I have searched, and saw a post by Gigi that you posted something similar about a year ago, but no one replied. What is the concensus on these two secondary air injection codes (Bank 1 & Bank 2). I have seen everything from my MAF, Cats, O2 sensors and everything in between.

Thanks for your help

could be some vac lines (most common) check the lines from the 2ndary air pump first ~

i had a similar cel for my 2ndary air injection that may be attributed to my cracked crank breather hose... cuz it went away a few weeks after i replaced it
