What is a Steering Angle Sensor and Why Calibration is Needed?

A steering angle sensor (SAS) is an electronic device located within the steering column that measures the precise position and rate of turn of the steering wheel. This data is fed to the vehicle’s ECU, which uses it to make real-time decisions for safety systems such as ESP (Electronic Stability Program), ABS, and traction control.

Calibration is the process of teaching the ECU the exact “zero” position of the steering wheel—when the front wheels are pointed straight ahead. The need for calibration arises when:

• A new steering angle sensor is installed.
• The steering column is disassembled or replaced.
• The battery is disconnected for an extended period.
• A wheel alignment or suspension repair is performed.
• ESP or ABS warning lights are on, indicating a sensor data mismatch.

Without proper calibration, the vehicle’s safety systems may not function correctly, leading to unpredictable behavior and a significant safety risk.
