What does this code mean?
P1416 (Air System bank 2-B)
My check engine light came on and some say this code could be why. It went away by itself, any ideas what this is?

Secondary Air Injections system, right bank.
The air injector check valves rust shut and cause this error.
The air injection pump turns on when the engine is first started.
Air is injected into the exhause manifold to lower emissions.
If the O2 sensor does not change readings during this time, the P1416 code will set.
If the pump was bad or there wasn't electricity to the pump, then you would get an error for both the right and the left bank.

Great, thanks! Is there any way for me to fix this or is it a dealer thing? Is it expensive?
