P2B22......

Get it occasionally immediately upon a cold start. Car starts and idles fine when it happens though...nothing mechanically or audibly would seem any different. Does not cause a CEL, just the "half engine" light on the tach. Clear it with the AccessPort and it never comes back...until it decides to randomly pop up during another start.

Anyone seen it? Anyone? Anyone? Anyone??

The codes that the R56 spits out drive me up a wall

 

Did you receive all these R56 trouble codes before or after the RMW tune ?

 

Stock, tuned, jcw turbo, old motor, new motor....doesn't matter, gotten various dme codes on each of those instances.

And for what its worth...I'm not even running an RMW tune at the moment. I'm on Alta cuz its around 110 out and I want lower boost until I get my meth kit.

 

For those that were just dying to know....lol, found out an answer.

2B22 is the DME code for the throttle valve actuator, and will result in an additional P-code of P1631 which is a fault in the opening/closing of the throttle actuator.

Stupid R56

 

Sounds like maybe a throttle body failing??

 

Yep....had to order a new one

 

Would you be interested in sending me your old one? One of my guys would like to try to fix it.

I have the same issue but could not figure out the problem.

Is there any solution available? would appreciate if somebody could share.

 

I new throttle body fixed mine. I run a repair shop and we have replaced many TB's when it has these codes

 

tks for sharing. I will order one.

 

No Problem. Let me know how it goes.

 

I'm getting the P1631 code. Bentley manual says it's the throttle body. Bentley manual also says that the throttle plate adaption values must be reset or the engine does not start. Is this correct?

I'm using the Torque app that can read and clear the codes, but I don't believe it can reset the throttle plate values.
