C0051Steering Wheel Position Sensor
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Covers the steering wheel position (steering angle) sensor and its circuit. The sensor reports absolute steering-wheel angle and rate to the ESC module, which combines it with yaw rate, lateral acceleration and wheel speeds to decide when the car is understeering or oversteering. The module sets this code for an out-of-range signal, an open or short, or a neutral/centre position that is not learned or is implausible. Honda documents DTC C0051-54, set when the steering-angle centre position has not finished its learn routine, which can occur after a battery disconnect and usually self-clears after a short straight drive; Mazda logs C0051:62 when the learned steering-angle value differs too far from the initial value. A fault disables stability control and sets the ABS/ESC warning lamp while base braking remains.
