I'd like to know as well, I've got the same message every day. I can temporarily disable the message and see the camera when reversing by pressing the backup sensor switch on the lower dash.

Just an FYI The shape and size of the letters & numbers on the injector is inconsistent from AC Delco and may not be counterfeit parts. I've just ordered a new AC Delco injector from Autozone part number 19420316. Part# on the injector is A 12709470, this replaces 12668393. I bought the truck a year ago and it looks like one of the injectors was replaced (see image below of injector still installed in the rail) You can see a variation in the size and shape of the letters and number. The new injector from Autozone, should be genuine AC Delco and the old one has been functioning for more than a year and 18k miles. So, I don't believe it's a cheap Chinese knock-off. So, I'm wondering if AC Delco has variations in their manufacturing. I noticed a similar variation when I ordered two front wheel speed sensors and the packaging and labeling was slightly different from each other. Which made me suspect one may be a counterfeit, but the sensors are both working fine now for months.

I wouldn't mind a cheap option to adjust for afm & tire size but according to Summit Racing this does not fit 2015 Sierra?
