Intake manifold runner stuck open P2004 Code
I am getting an error code P2004 Intake maniford runner control stuck open. . . it is pointing to the APV. Have you run into this problem before?
I pulled the ACV off. There is a gear there . . . to open or close the intake runner. The gear will not turn by hand with the vehicle off . . .is this normal?
Your help is appreciated.

now i dont know too much about the apv and the valve it controls but i have the same problem and i took the apv motor off and tried to turn the big gear that it turns and it would only turn about a half inch either way and its suppose to turn one full turn both ways. so the only thing i cn think of is that it has alot of carbon or a peace of carbon droped into the valve and got it stuck. but im having mazda do a decarbonize the engine and hopefully it will free up the exhaust valves. if not then i will have to tear apart the engine and clean out the exhaust valves. i hope this helps you and if you get your engine fixed plz tell me what they had to do to fix it.
