C0069Yaw Rate/Longitude Sensors
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0069 is a plausibility code for the yaw rate and longitudinal acceleration sensors taken together. When the vehicle brakes in a bend, yaw, longitudinal and lateral motion must stay in a physical relationship; if the two signals keep contradicting each other or the rest of the inertial set, one channel has drifted, both share a fault, or the cluster has shifted on its mount. NHTSA's brake safety study lists yaw rate and longitudinal acceleration as inputs of the stability module and notes that several vehicle dynamics sensors are often combined in one unit, which is what makes such cross-checks possible. The module stores C0069, switches off stability and related functions and lights the ESC lamp; base braking remains. No manufacturer documents this code publicly.
