Mine threw that code two weeks ago. Cel is still on. Dealer said that the part is back ordered and can't get it. Must not be to important.

dealer called back and said it was emmisions related, reductant heating element. Another reason why deleting all this crap after the warranty is looking better and better.

yeah, that heater is built into the sender, they go out like crazy. Even on the 2012's+ . Now they're making dealers get prior approval before repairing them

Anyone else have this part go bad? Dealer still can't get the part. Meanwhile the light is still on. I'd never know if it throughs another code for something else.

My 2011 has been at the dealership for almost 2 weeks with the same problem and they can't give me a date of when the pump will be in because it's on national back order.

I'm still driven mine. They never said I shouldn't. Should I? Is yours just sitting?
