EVAP emission system canister closed on 2005 Kia Sedona

check engine light came on, took to have it checked, code P2422 showed on computer. what is this? the check engine light is still on.

I think that the code may be a P0422 or P0442. I can find no P2422 code for a Kia like yours.
You will need to have the Evaporative Emissions System inspected to trace down the cause of the fault code. I do this daily, because I do Emissions Diagnosis in California, which has an intense Emissions Inspection and repair program.
here is a little about the EVAP system
thank you for the info. I will have it looked at immediately. funny thing was that I ended up putting higher grade gas in the tank and the light went off.
