Mine was throwing the same code and the check engine light is on. Dropped it off at the dealer this morning, and they said +- $500 to repair. They also said the intake has to be pulled. Is that true?
Guys
How do I fix this code, I know it is air bank #2, which I assume is a sensor, but can someone advice?
Thanks,
Tara
The check valve can often be cleaned by using a carb cleaner down the hose, let it sit 15 minutes or so, use compressed air to blow it through and re-connect your plumbing. Solved my problem 100%, no light in over a year!
