Check Brake system light Brand new Raptor

[FordTechOne]

Power brake vacuum sensor did not do the trick. Light still comes on, usually after driving with cruise control..... Now I have an engine misfire code. Took to dealer and they report having no vacuum when driving with cruise control on. Ordered new brake booster. Hopefully this does the trick, truck has 1.600 miles on it.

It’s a turbocharged engine...you’re not going to have much vacuum at highway speeds with cruise control. Sounds like they are guessing with the brake booster at this point unless they found a leak in it. Can you ask for the DTCs that were set?

Did you ever get this solved? Mine has been doing this since I bought it (usually at highway speeds after 5-10 minutes). Was going to try the power brake vacuum sensor myself but haven't gotten around to it yet.
