Steering Angle Sensor Error

This code indicates an issue with the steering angle sensor or its circuitry.

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 monitors the angle of the steering wheel and sends this info to the vehicle's computer. If it fails or has a wiring issue, the computer can't tell how much you're turning the wheel, which affects things like stability control and power steering.

What the computer is actually seeing

The vehicle's computer expects to see a specific voltage or resistance signal from the steering angle sensor corresponding to the current angle of the steering wheel—typically between 0.5V to 4.5V depending on the wheel position.

What a healthy reading looks like

Expected voltage range from the sensor should be between 0.5V (straight ahead) and 4.5V (full lock left or right).

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 leading to the steering angle sensor. Look for frayed wires or corrosion.
  2. 22. Measure the voltage at the steering angle sensor connector with the key on and the steering wheel at the straight-ahead position. Should be around 2.5V. If not, repair any wiring issues identified.
  3. 33. If the voltage is correct, use a scan tool to check for additional codes and to re-calibrate the steering angle sensor if necessary. Follow manufacturer-specific procedures for calibration.

Common causes

  • Faulty steering angle sensor
  • Wiring issues or damaged connectors
  • Incorrectly calibrated sensor
  • Faulty vehicle stability control module
