Check Engine Light
IMy check engine light has just come on. It is an '02. I went to Autozone and they scanned it and came up with P1416 code. Does anyone know what that is or how serious it is?
Thanks in advance.

You can check all the codes yourself on the DIC, just an FYI. Also this link might be useful....

The code is P1416 AIR System Bank 2.
Not quite sure what the fix is though.

You can look up codes through the DTC and learn how to clear then at http://www.corvettedoctor.com/Code_Main.html
P1416 - Secondary Air Injection (AIR) System
I get this one sporatically too. Have no idea what it is, but I clear it and it goes a way for a while. Does not seem to affect the way the car runs.

P1416 is for Bank2 - the passenger side of the engine.
The AIR pump turns on when the engine is cold, adding air into the exhaust to loweer exhaust emmisions. Once the engine warms up, the AIR system is turned off.
However, the PCM tests the system occasionally, by turning on the AIR pump and using the Heated O2 sensors to ensure that air is being added to the exhaust. Your PCM is seeing air being added to the left bank, but not the right.
Many people have fixed this problem by blasting some WD40 into the checkvalves, and exercising the check valves with compressed air. Unfortunately the passenger side check valve is located behind the intake manifold, so you'll have to remove that to get to the valve. That's why, if you can just spray in WD40 from the left side, hopefully it will fix the problem.
