Steering Angle Sensor Range/Performance Problem
The steering angle sensor signal is out of expected range or 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)
Your car has a sensor that tracks the position of the steering wheel. If this sensor is sending weird signals, it could mean it's faulty or misaligned.
What the computer is actually seeing
The Vehicle Control Module (VCM) expects a steady voltage output from the steering angle sensor as you turn the wheel, typically around 0.5 to 4.5 volts depending on the angle. If it sees values outside this range or inconsistent changes, it throws a code.
What a healthy reading looks like
0.5V to 4.5V output from the sensor corresponding to steering angle, typically 0° to ±90°.
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. Check wiring and connectors for damage or corrosion. Repair any issues found. Decision: If issues were found and fixed, clear codes and retest. If not, proceed to next step.
- 22. Inspect the steering angle sensor for physical damage or misalignment. Remove and reseat if necessary. Decision: If the sensor appears damaged, replace it; if not, proceed to next step.
- 33. Use a scan tool to monitor the steering angle sensor data. Expect steady changes in voltage as the wheel turns. Decision: If data is erratic or out of range, replace the steering angle sensor. If data is normal, check for software updates or calibration issues.
Common causes
- Faulty steering angle sensor
- Wiring or connector issues
- Improper calibration after alignment
- Faulty steering rack or mechanical binding

Frequently asked questions
Can I drive my vehicle with this code?
It's drivable, but you may notice issues with traction control and stability systems. Get it fixed soon.
Will the problem come back after I clear the code?
If the underlying issue isn’t resolved, the code will likely return after clearing.
Why does this code sometimes pair with other codes?
Multiple codes can indicate related system failures, like issues with the ABS or traction control affecting sensor performance.
