Steering Angle Sensor Circuit Malfunction
The steering angle sensor is reporting a fault.
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 far and in which direction you turn the steering wheel, and it's not working right now due to an electrical issue.
What the computer is actually seeing
The vehicle's computer expects a voltage signal indicative of the steering wheel's position but is receiving erratic data or no data at all, usually between 0.5 volts (full left) and 4.5 volts (full right).
What a healthy reading looks like
Typical operating range is 0.5 to 4.5 volts, with a steady signal expected during turning.
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 going to the steering angle sensor for physical damage or corrosion. Decision: Are any issues found? If yes, repair the wiring. If no, proceed to step 2.
- 22. Check the sensor's output voltage using a multimeter while turning the steering wheel. Expected voltage should change smoothly between 0.5 and 4.5 volts. Decision: Is the voltage within range? If yes, go to step 3. If no, replace the steering angle sensor.
- 33. Inspect the vehicle’s ground connections and ensure they are clean and tight. Decision: Are the grounds okay? If yes, further diagnosis of the vehicle's module may be needed. If no, repair grounds and retest.
Common causes
- Damaged wiring or connectors to the steering angle sensor
- Faulty steering angle sensor
- Poor grounds or electrical connections
- Corrosion in connectors

Frequently asked questions
Is it safe to drive with this code?
Yes, but handling may be affected, especially in emergency situations.
Will this code come back after I fix it?
If the underlying issue is resolved, the code should not return.
Why does this code pair with other codes?
Issues in the steering system often trigger multiple faults due to interconnected sensors and systems.
