Subaru Steering Angle Sensor by Model
What a steering angle sensor does
A steering angle sensor measures the rotation angle and rate of the steering wheel. The signal is used by stability control, traction control, electric power steering, and driver assistance features such as lane keeping or adaptive headlights. On many Subaru vehicles the sensor is housed inside the steering column assembly, often as part of the clock spring or steering roll connector rather than as a separate bolt-on part.
Common symptoms of a faulty sensor
Reported indicators include an illuminated stability control or traction warning lamp, a steering warning message, loss of power steering assist, or diagnostic trouble codes related to steering angle calibration or internal sensor faults. Because the sensor is frequently integrated with the steering angle assembly, some repairs require replacing the entire roll connector or column module rather than only the sensor element.
Sensor location and configuration by model line
Subaru does not use one identical steering angle sensor part across all models. The exact layout depends on model year, generation, and whether the vehicle has electric power steering or hydraulic assist. In general, the sensor reads from the steering column, near the wheel, and communicates over the vehicle CAN bus for recalibration after alignment, column work, or battery disconnect.

Calibration and reset considerations
After a sensor replacement, steering rack work, or sometimes a battery disconnect, the sensor may need to be initialized or zeroed with a compatible scan tool. Some systems allow a manual procedure through steering wheel movement sequences, but Subaru documentation generally specifies a diagnostic tool for correct calibration. Failure to perform the reset can leave stability control inactive or produce incorrect steering effort.
Replacement guidance and limitations
Because several Subaru platforms integrate the steering angle sensor into the clock spring or roll connector, a sensor fault may require replacement of the entire module. Always verify the correct part for the specific model year, generation, trim, and steering system type. Documented repair procedures emphasize disconnecting the battery and following airbag safety precautions before removing any steering column component.
What is not covered by supplied evidence
The supplied coverage does not provide exact part numbers, torque values, step-by-step removal instructions, wiring diagrams, or model-year-specific sensor positions for every Subaru variant. These details vary sufficiently that a direct answer for one trim cannot be assumed for another without checking the specific vehicle identification.
