My '00 T/A's SES light came on the other day, I had it checked, cleared, and then a week later it came back on. This is what code it is giving me:

AIR System 1416 Secondary Air Injection, Bank 2

A mechanic buddy of mine said this is either a vacuum line problem or possibly a false reading since I have an MTI clear air lid and/or SLP cold air induction. Has anyone else gotten this code and how can I fix it so that I can clear the code for good?

 

Most likely the passenger side air check valve is gunked up - inexpensive and easy to replace yourself. Happens all the time. Search this forum for "P1416" lots of threads.

 

Had one similar, I'll let you know what my Ls1 mechanic buddy's did. Can't remember off the bat, but it had to do with corrosion which made my sensor's loose, but I'll be back and read his notes.
