    Start saving. I was there and done that. Part of problem is tune and part is your actuator.

    Just curious, did you start out with just the P226C or did you have this code in conjunction with others?

    I had lots of issues.

    The u010 and p003 codes were the start.

    They were partly tied to a bad nox sensor.

    I also found the factory tune was stuck in a rich mode.

    Out came a lot when i hit the pothole, but i started having issues with your code.

    The truck would go a few days before it would pop up again.

    The code was always preceded by the engine surging at idle when stopped as the actuator tried to keep up.

    You can confirm the issue by graphing the commanded and actual positions for the VGT.

    You will find the actuator is hanging at a point and the graphs diverge from each other.

    They catch back up but the actuator not moving enough is the issue.

    The factory units are known to have weak motors and to develop leaks, which burn out the electronics.

    The vanes themselves also develop slop to them.

    They ride through an alignment ring that needs to rotate in the exhaust housing.

    My belief is the groove for the ring gets filled with carbon and it stops the vanes from moving freely, burns up the motor.

    You can clean it up dropping the down pipe and cleaning out the housing using some brake clean and intake valve cleaner.
