Steering Angle Sensor Calibration Invalid Data
The steering angle sensor is not providing valid calibration data to the vehicle's computer.
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)
Inside the computer, the steering angle sensor sends data about the steering wheel's position. If it’s miscalibrated or faulty, the computer can't read where your wheel is pointing.
What the computer is actually seeing
The computer expects a linear signal from the steering angle sensor, usually a voltage between 0.5V to 4.5V that changes as the steering wheel turns. If calibration data is invalid, it may see inconsistent or out-of-range values.
What a healthy reading looks like
Steering angle sensor voltage typically ranges from 0.5V to 4.5V, corresponding to -30 to +30 degrees of steering input.
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 wiring and connectors for the steering angle sensor for damage or corrosion.
- 22. Check for any trouble codes in other modules that may indicate a related issue (e.g., ABS or traction control).
- 33. Verify the steering angle sensor's voltage output with a multimeter (look for 0.5V to 4.5V as you manually turn the steering wheel).
- 44. Confirm if the steering angle sensor is calibrated correctly. Refer to the service manual for calibration procedures.
- 55. If the above checks are clear but the code persists, consider replacing the steering angle sensor.
Common causes
- Faulty steering angle sensor
- Improper installation or calibration of the sensor
- Damaged wiring or connectors
- Unrelated vehicle module issue

Frequently asked questions
Can I drive with this code?
Yes, but steering assist and safety features may be compromised. Fix it soon.
Why does this code relate to the ABS system?
The steering angle sensor is crucial for ABS and traction control to function properly. If it's faulty, those systems may not operate effectively.
Will this issue come back after a repair?
If the underlying problem is fixed and calibration is done correctly, it shouldn't return.
