After 150 miles of freeway and then pulling into town, The Check engine light lit.
Error 17688 Air control valve N212 "Flow to low"
P1280-35-00
Could this be the TSB ice in the hose issue?
It is cold here!

Re: This fault is set if pressure of air to injectors is to low
Thanks so much
I believe I was at the "Check for clogged hoses" operation. and recalled reading about an "iced up condition.
Since this code has shown up several weeks ago, and now again. It seems to come and go.
The DTC is cleared now, next time I have the plastic off (Soon if I plan to check the CC assembly ;-0) the hoses will come under scrutiny as well.
Thanks

It was -25C this morning in Chicago. My coolant was good to -18C.
My radiator froze. The car overheated on my way to work. Lucky me we had an open dock at the shipping department so I put the car in to warm up. Fortunately there is no damage, everything is fine now.
