C0185Lateral Acceleration Sensor Range/Performance
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- C0185 is missing from the accessible J2012 lists and from the NHTSA bulletin index, and no maker documents it, so it is not publicly verifiable; its title is shared with C0499. It describes a lateral acceleration signal that is electrically intact but does not fit the motion of the car. GM-based service data for the Saab 9-4X file exactly this case under C0186 with symptom 5A: an offset outside its window, or a value that disagrees with yaw rate, steering angle and speed. Honda patented a check that flags the sensor when its reading exceeds the smaller of V²/R and 1 g in both left and right turns, so a slope offset alone does not trip it. A Bosch patent covers clearing such a fault only after offset and model comparisons pass while driving straight and cornering.
