Steering Angle Sensor Fault
Indicates a problem with the steering angle sensor's signal.
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 detects how much you turn the steering wheel and sends that info to the vehicle's computer. If it fails, the car can't properly figure out how much the wheels are turned, which can affect handling.
What the computer is actually seeing
The computer is looking for a voltage signal between 0.5V and 4.5V from the steering angle sensor. If this signal is outside of this range, a fault code is triggered.
What a healthy reading looks like
Expected values are a steady signal of 0.5V to 4.5V depending on the wheel angle, with a center position around 2.5V.
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 damage or corrosion. Repair as needed. 2. Check the vehicle's alignment; ensure it's within manufacturer specifications. Adjust if necessary. 3. Use a scan tool to read live data and monitor the steering angle sensor voltage. Verify it fluctuates between 0.5V and 4.5V when turning the wheel. 4. If the signal is out of range, replace the steering angle sensor. 5. After replacement, calibrate the new sensor according to manufacturer specifications.
Common causes
- Faulty steering angle sensor
- Damaged wiring or connectors
- Incorrect alignment or calibration of the sensor
