C121E Code

Dash lights for ESP came on the other day SuperChips says its "brake pressure sensor comparative performance". What on earth could be setting that off? Everytime I clear it, it doesn't turn off the lights and it comes right back. I also had a code about the wheels being our of range or something but it cleared no problem and hasn't come back.

Thanks for the help,
