Steering Angle Sensor Fault
There's an issue with the steering angle sensor reading.
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 measures how much you turn the steering wheel. If it reads incorrectly, the car's systems that rely on that info may not work properly, affecting things like stability control.
What the computer is actually seeing
The computer expects the steering angle sensor to provide a voltage between 0.5V (full left) and 4.5V (full right), corresponding to the wheel position. If the signal is outside this range or missing, a fault code is triggered.
What a healthy reading looks like
0.5V to 4.5V for steering angle; expected values will vary based on the specific vehicle model.
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.
- 1Inspect the wiring and connectors of the steering angle sensor for damage or corrosion. Repair as needed. Decision: If damage is found, repair and retest. If no damage, continue.
- 2Check the sensor voltage output with a multimeter while turning the steering wheel. Expect a smooth transition between 0.5V and 4.5V. Decision: If voltage is erratic or absent, replace the steering angle sensor. If within range, continue.
- 3If the sensor is replaced or appears fine, perform a steering angle sensor calibration with a scan tool. Decision: If calibration completes successfully and no codes return, repair successful. If code returns, further diagnosis on the module or wiring needed.
Common causes
- Faulty steering angle sensor
- Wiring issues (frayed or broken wires)
- Loose or corroded connectors
- Calibration needed after steering system service
Typical repair cost

Frequently asked questions
Is it safe to drive with this code?
While the vehicle may still be driveable, it can affect traction control and stability features, so it's better to fix it soon.
Will this issue come back after repair?
If properly diagnosed and fixed, it shouldn't return unless there's another underlying problem.
Why does this code pair with other steering codes?
Steering systems are complex; issues in one component often affect others, leading to multiple codes.
