About C0051

C0051 is a generic (obd-ii standard) chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C0051 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

Because C0051 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The steering wheel position sensor, also called the steering angle sensor, reports steering wheel angle and rate of turn to the ABS, traction control, and electronic stability control systems so they know the driver intended direction. DTC C0051 sets when the control module sees a signal from this sensor that is missing, out of range, implausible, or not matching the other dynamic sensors such as yaw rate and lateral acceleration. The sensor is usually mounted at the base of the steering column, often built into the clock spring assembly, and reports its angle either as an analog signal or ove...
