Steering Angle Sensor Fault

The steering angle sensor has detected a problem and is not functioning properly.

Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.

What it means (plain English)

The steering angle sensor tells the computer how far and fast you're turning the steering wheel. If it fails, the car doesn’t know what direction the wheels are pointed, which can mess with stability control and traction.

What the computer is actually seeing

The computer expects a signal from the steering angle sensor that indicates the angle of the steering wheel. Typically, this is a voltage signal that changes as you turn the wheel, generally between 0.5 to 4.5 volts.

What a healthy reading looks like

The voltage signal should change proportionally to the steering wheel position, usually ranging from 0.5V (fully left) to 4.5V (fully right) when turning it.

Guided diagnostic — the DiagCoach way

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

  1. 11. Inspect the wiring and connectors to the steering angle sensor for damage or corrosion. Fix any issues found.
  2. 22. Check the sensor's voltage signal with a multimeter as you turn the steering wheel. Confirm it changes from 0.5 to 4.5 volts smoothly. If not, the sensor is likely faulty.
  3. 33. If the sensor appears good, check for steering column misalignment or other steering component issues. Perform necessary adjustments or replacements. If problems persist, consider recalibrating the sensor after parts replacement.

Common causes

  • Faulty steering angle sensor
  • Damaged wiring or connectors to the sensor
  • Steering column misalignment
  • Calibration needed after steering component replacement

Frequently asked questions

Is it safe to drive with this code?

It's moderate severity; you can drive but should fix it soon to maintain proper handling and safety features.

Will the problem come back?

If caused by a wiring issue or faulty sensor, it may return unless those parts are repaired or replaced.

Why does this code appear with traction control issues?

The steering angle sensor is critical for traction control systems; if it fails, it can lead to traction loss when needed.
