Steering Angle Sensor Calibration
The steering angle sensor is out of calibration or 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 computer thinks the steering isn't where it should be when you turn the wheel, which can mess with stability control and other systems that rely on steering info.
What the computer is actually seeing
The steering angle sensor outputs a voltage signal that changes based on steering wheel position. At center position, you should see a typical voltage around 2.5V. When turned to the left or right, the voltage should vary between 0.5V (full left) and 4.5V (full right).
What a healthy reading looks like
Steering angle voltage should range from 0.5V (full left) to 4.5V (full right) with 2.5V at center position.
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.
- 11. Inspect the steering angle sensor connector and wiring for damage or corrosion. If damaged, repair or replace wiring/connectors.
- 22. Check the battery voltage. Must be between 12.4V and 12.8V with the engine off and around 13.7V to 14.7V with the engine running. Replace battery if below this range.
- 33. Use a scan tool to check for additional codes related to steering or stability systems. Address any related codes before proceeding.
- 44. With the scan tool, view live data for the steering angle sensor. Verify that the voltage signal changes as you turn the steering wheel. If not, replace the sensor.
- 55. If the sensor is changing correctly but the code persists, perform a steering angle calibration process as per the manufacturer instructions.
Common causes
- Faulty steering angle sensor
- Wiring issues such as fraying or corrosion
- Improper steering angle calibration after repairs
- Faulty steering rack or linkage issues

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive until the issue is resolved, as it can affect stability control and may lead to unsafe handling.
Will this code come back after reset?
Yes, if the underlying issue isn't fixed, the code will reappear after the first drive cycle.
Why does this code pair with other codes?
Steering angle issues can impact other systems like traction control and electronic stability programs, causing multiple codes to trigger.
