heres another picture of the valves.
number 12 and 13.

12 & 13 are both on the driver side except 13 is under the intake manifold and harder to change.
pull the rubber hose out and stick your finger inside the valve hole to check for water. if theres water in there then theres your failed valve.

you can change it or just get cobb access tuner race to disable the codes. its only there for emissions. it wont affect drivability. With the cel on, you're probably on limp mode. Also stick a rag inside the hole to absorb the water out if you decide to just delete the cel.

these valves mostly likely failed because water gets inside the valve, causing it to rust and get stuck.
One of the valve sits under the intake manifold ,and its right under the hood vent. When it rains or when you wash your car, the water goes down the hood vent. I think this is how the water gets in through condensation.Just speculating.

see those holes on the 2 valves after you remove the black y-hose coming from the air pump?
Test for water by sticking your finger or a rag deep inside the hole.
