Muh Googling brings all the boys to the yard. Damn right, it's better than yours. I could teach you but I'd have to charge.

The BPS provides a signal to the Powertrain Control Module (PCM) indicating the brakes are applied. The BPS is normally open and mounted on the brake pedal support.

It had no light and I had a tail light sequencer installed and the code went away as soon as I removed it. I also have U0401 DTC. There are no lights on the dash only the wrench light and it doesn't let me use cruise control or hill start assist so thats why I want to fix it
