SAS (Steering Angle Sensor) Voltage Too High
The Steering Angle Sensor voltage is above the expected range.
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 the angle of the steering wheel, and a voltage reading that's too high means it's detecting a signal that's off from what it should be.
What the computer is actually seeing
The Engine Control Unit (ECU) is seeing a voltage from the SAS that exceeds the normal threshold, typically above 4.5 volts.
What a healthy reading looks like
Expected voltage range is between 0.5 volts and 4.5 volts, with a typical center value around 2.5 volts when the steering wheel is straight.
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 the Steering Angle Sensor for any signs of corrosion or damage. Repair as needed. Decision: Do you find any issues? If yes, repair them and retest. If no, proceed to step 2.
- 22. Verify the voltage at the SAS connector with a multimeter. Key on, engine off. Measure voltage. Decision: Is it within 0.5V to 4.5V? If yes, proceed to step 3. If no, replace the sensor and retest.
Common causes
- Faulty steering angle sensor
- Corroded or damaged wiring
- Bad connectors or loose connections
- Calibration issues with the steering angle sensor

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you can drive, but you should address it soon to maintain proper vehicle handling.
Will this code come back after clearing?
If the underlying issue isn’t resolved, yes, the code will likely return.
Why does this code sometimes pair with other steering sensor codes?
Multiple faults can indicate issues with the entire steering sensor system, so it's normal for related codes to show up.
