ESP/BAS light code C121E–BRAKE PRESSURE SENSOR COMPARATIVE PERFORMANCE
I've got this code on my 07 along with the cruise control not working. I've scanned the codes and attempted to clear it but it comes right back. I checked all the fuses, what is a brake pressure sensor and do the go bad often?

its usually because your brake fluid levels are lower than they like. Fill it up and see if you still have the issue. If you do, it could be your clock spring. Have you had that replaced?
