Steering Angle Sensor Circuit Malfunction
There’s a problem with the steering angle sensor or its circuit.
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 tracks how far your steering wheel is turned. If it fails or the wiring gets damaged, the car might struggle to steer properly, or features like stability control won't work correctly.
What the computer is actually seeing
The computer measures the voltage from the steering angle sensor, which typically outputs between 0.5V (straight ahead) and 4.5V (full lock). If it sees a signal that’s outside of this range or drops out completely, it triggers the code.
What a healthy reading looks like
Voltage from the steering angle sensor should be between 0.5V and 4.5V; the expected normal values vary based on the steering position: 0 degrees = ~2.5V, left lock = ~0.5V, right lock = ~4.5V.
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 the steering angle sensor. Look for frays, corrosion, or poor connections. If there are visible issues, repair or replace as necessary. Decision: If wiring is fine, proceed to step 2. If wiring is damaged, resolve before continuing.
- 22. Measure the voltage output of the steering angle sensor with a multimeter while turning the wheel. It should vary between 0.5V and 4.5V. Decision: If the voltage is within range, go to step 3. If the voltage is out of range, replace the steering angle sensor.
- 33. Check if the last known good calibration is stored in the system. If the sensor was replaced recently, it may need to be calibrated. Use the manufacturer's scan tool for calibration. Decision: If calibration resolves the issue, clear codes and retest. If not, consider ECM issues.
Common causes
- Faulty steering angle sensor
- Wiring damage or corrosion in the sensor circuit
- Poor connection at the sensor or the ECM
- Steering column damage
- Sensor calibration issue

Frequently asked questions
Is it safe to drive with this code active?
It depends on the symptoms. If you notice abnormal steering behavior or loss of traction control, it’s not safe to drive until fixed.
Will the issue return if I just clear the code?
Yes, unless the underlying problem is resolved, the code will likely return after clearing.
Why does this code show up with stability control issues?
The steering angle sensor provides data vital for stability control systems to function correctly; if it fails, the system can't operate as intended.
