C0287Longitudinal Acceleration Sensor Circuit

  • Generic OBD-II code · Chassis
  • Needs a drive cycle to confirm a fix
How the car detects it
The publicly available J2012 lists do not contain C0287, and no maker uses it for an ESP Performance fault. In later GM brake systems the number belongs to the longitudinal acceleration sensor: the Saab 9-5 of 2010 and 2011 and the 2011 Saab 9-4X file it under the multi-axis sensor that also delivers lateral acceleration and yaw rate over CAN. It sets when that signal is missing, disagrees with the speed change of the car or has an offset outside its window; subcode 4B marks a calibration never learned, 71 invalid data. Only hill start assist is switched off. GM bulletins PI1525 (2014–15 Regal, Malibu, Sonic) and PIT5427 (2010–15 Equinox and Terrain, corroded connector X411) list it with C0186 and C0196. Older GM tables used the number otherwise.
