Hi, Just wondering if anyone ever got a P15BB code Brake Booster System Leak Detected.
I cleared the code it did not ever lite the MIL. I only found this using an OBD2scanner.
Just interested how this would happen and not notice any driving or brake issues.

 

Bumping this ancient post because the same thing happened to me yesterday while driving. No change in brake pedal feel, fluid level is right where it should be. From what I can tell other possibilities include a brake pedal sensor (I would think a vacuum leak would cause a difference in pedal feel, but who knows). It flipped a couple times during drives yesterday, just while cruising down the highway. It did not trigger again this morning on the way to work. Anyone else have this warning pop seemingly at random?
