I'm sure this has been discussed here before but all the discussions I see on this DTC are coupled with performance issues or loss of exhaust brake and I have neither of those... I just have the codes P226C and U010C. Keep popping up. 2013 2500 with approximately 170k miles. For a while it was clearing on its own every couple starts now it's on constantly. Not too concerned since it isn't affecting performance at the moment but when it comes inspection time 馃槵 any advice? Solutions? I have not checked the plug at the controller for 12+ and ground but since the actuator seems to be working I figure it must have power.

Where are you that a code for something other than emissions would cause it not to pass inspection?

As to the slow boost response code, could be carbon keeping the turbo vanes from moving as quickly as they should. You'd still get enough boost for power, and vanes closing enough to make the EB work, just sticking so they don't move as quick as they should.

You could pull the turbo and take it to a rebuilder to get it freshened up.

I don't know for sure that this would cause it not to pass... but when I was a mechanic (years and years ago) any check engine light would be a failure... but this was very early OBDII days. Is this something I would be able to detect if I pull the actuator and move the little arm that slides the vanes manually?

Sounds like Turbo. Same issue I had recently. Dealer was up to $12,000 if intercooler needed replaced too. But I got it fixed for a little less. If you do it, and use new parts, figure $5000 to $6000. I suppose you could cut corners and just fix the actuator, $3000 or so.

Would be worth a try.

At least it isn't throwing the code for the actuator, but if it keeps on that would probably be next, jamming the actuator will cause it to fail.


Scratch that, wasn't paying attention to the other code, lost comm with the turbo, probably means the actuator is already in trouble.

I found a site that sells refurbished turbos for like $1200 but they list 07-12... Mine is a 13. I am checking with them to see if they offer one for the 13 or if there is even a difference. Comes with refurbished and "synched" controller as well.

Really feels like the controller comp is just failing. Given that the code is intermittent and it's a communication failure code not a low or slow boost code. Site I found that sells refurb turbos also sells new and refurbished controllers... Unfortunate that you need a proper OBDII computer to run the controller auto sync.

Well... I gave it the old Shade tree mechanic reset (unplugged, inspected plug, and re-plugged) HAHA... The light has gone out for now. I seriously doubt that fixed it but figured I would update. lol
