same problem
There is an older thread on here if you type in that error code in the search box. Parts run from 32 bucks to $150. Looks like an easy fix. I have to correct this on my 06 Silverado.

Part # 25932571 is what you are looking for. It's the vent solenoid which is sometimes confused with the purge solenoid. This part is located under the bed more than likely towards the spare tire. I found the part @ oehq.com for like $19! Don't get bent over the service counter at the dealership!
