New Truck SCREAMS check my engine
Hi guys,
Hopefully someone here will have had the same code come up. I have a 2017 2.7 Ecoboost and the check engine light came on today!!
The code is P219B Bank 2 Air-Fuel Ratio Imbalance
Sooooo, any advice, the two local dealerships within 45 minutes can't get it in for a week or more!
Thanks everyone!

Do you have an aftermarket cold air intake, or aftermarket exhaust?

I really hope that I don't get stranded anywhere. To me it seems like it might be a turbo issue but then again you think there would be a code for that too??

Hi Summers22, it seems to start, drive and run OK for now. I did notice that it was doing some weird start/stop stuff today so I don't know if that is related but I don't like having a new truck with a CEL on. Especially because it is the family vehicle.

OK friends, the check engine light went out. That gives me a bit easier breathing but I'm still going to get it checked out. What an odd thing to have happen out of nowhere?
