Had that code pop up once.
Used a SCT Scanner to Clear it off. Has not come back yet. When it happened I did a search of other posts ,, result of the PD Blowers like the Whipple on my car. Appears the blower can reduce the vacuum in the booster long enough for the sensor to set a code. Did'nt appear to effect my cars braking , and has not hppened again.

Did you actually check your brake booster hoses?

That or use a 0psi check valve on the brake booster before the sensor.

I know this post is old but there is a little design flaw with the hose connected to the brake booster pressure sensor, if you follow the hose back you will find that it's touching a very hot surface on the hose making it almost melt and this is what made my light turn on, it only takes 1 hundredth of a millisecond to turn it on. So i placed high temperature resistant material around the hose to prevent this from happening again.
