Hi,
The idea that the OD doesn't work properly until the air box is removed, check the wiring going to it for damage, bare wires, and make sure the connectors are clean, tight, and free of corrosion. Something may be getting moved.
Next, pic 1 below identifies the codes. Pics 2 and 3 are the diagnostics specific to the codes you gave me. Take a look through them and let me know if you are comfortable performing them.
Let me know.
Take care,
Joe
