Steering Wheel Angle Sensor Performance Problem
Indicates an issue with the steering wheel angle sensor's performance.
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 wheel angle sensor measures how much you've turned the wheel. If it's not sending the right signals to the computer, your vehicle might not control stability properly.
What the computer is actually seeing
The computer expects a consistent voltage signal corresponding to the angle of the steering input. When the sensor is turned, the voltage should change smoothly from about 0.5V (straight ahead) to over 4.5V (full lock left or right).
What a healthy reading looks like
Voltage from the steering angle sensor should smoothly range from 0.5V to 4.5V depending on the steering position.

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 wiring and connector at the steering wheel angle sensor for damage or corrosion. Repair as needed. Decision: Is the wiring intact? Yes: Go to step 2; No: Repair wiring.
Common causes
- Faulty steering wheel angle sensor
- Wiring damage or poor connections
- Incorrectly aligned steering wheel
- Failed power steering module

Frequently asked questions
Can I still drive the vehicle with this code?
Yes, but the stability control may not function correctly, increasing the risk of losing control in slippery conditions.
Will this issue return after fixing?
If the underlying problem (like wiring or the sensor) is properly resolved, it shouldn't return.
Why does this code appear with other stability control codes?
These codes often appear together because the steering angle sensor is critical for the stability control system's operation.
