C0065Vertical Acceleration Sensor
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0065 covers the vertical acceleration sensor, which measures up-and-down acceleration of the body. Bosch's inertial measurement unit shows where it lives today: one housing measures the rates of yaw, pitch and roll plus vertical, longitudinal and lateral acceleration and serves several control systems at once. The vertical channel supports rough-road and wheel-lift detection, rollover recognition and, with adaptive damping, the suspension control. The module checks the vertical reading against the other channels and stores C0065 when it is out of range, stuck, noisy or implausible. Depending on the vehicle, stability or suspension functions are reduced and the ESC or suspension lamp lights, while normal braking is unaffected. No manufacturer documents this code publicly.
