Default P2009 error is250 NON INVASIVE CHECK

Removed 2 screws (they were on real tight) on the actuator flap motor and found a nut in there loose and flopping around. Put 2 drops of blue Loctite and fastened the nut. The original idea of this fix was found here.

Had to disconnect a bunch of harnesses and remove the throttle body to get in there. Hopefully, that fixes my problem.
Firstly I had the same issue and yes it is that little bit in the motor. I figured something out today though. A non invasive check before removing the manifold. If the arm circled in the back swings left to right, then yes that gear is loose. After the fix this arm has no play.

Sits right behind the coolant cap

Default Same problem

Last week, I did the DIY 60k service including replacing filters, spark plugs, and brake fluid. After putting everything back together, the engine started up with VSC check engine and the track control light. So I checked to make sure the sensors are not loose, clean the MAF sensor, disconnected the battery to reset. The engine light went away for couple days and came back again. I repeating the "reset" process and it sure solved the VSC issue but it keeps on coming back.

So I stopped at auto zone and they came out with the code: "P2009 Intake Manifold Runner Control Circuit Low Bank 1". Does anyone had the same issue and got it solved? I'm thinking of the sensors got loose but there are many and I dont know which one is bank 1. Please help. Thanks

Andy
