Steering Angle Sensor Fault
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 which direction your steering wheel is turned. If it sends incorrect signals to the vehicle's computer, problems with controls and stability can happen.
What the computer is actually seeing
The computer expects a continuous voltage signal that changes as the steering wheel turns, typically between 0.5V (full left) and 4.5V (full right), with a center position around 2.5V.
What a healthy reading looks like
Steering angle sensor output should range from 0.5V to 4.5V corresponding to turns; values around 2.5V when centered.
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.
- 1Check for any visible damage to wiring and connectors related to the steering angle sensor.
- 2Using a multimeter, measure the voltage output from the steering angle sensor - should be between 0.5V and 4.5V when the steering wheel is turned.
- 3If voltage is out of expected range, inspect the sensor for failure or loose connections.
- 4Check the vehicle's power steering fluid level; low fluid can cause erratic sensor readings.
- 5If all checks are good, clear the code and road test the vehicle to see if the code returns.
Common causes
- Faulty steering angle sensor
- Wiring issues or short circuits
- Connector corrosion or damage
- Power steering system problems
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive but expect issues with stability control and steering response.
Will the fault code come back after clearing it?
If the underlying issue isn't fixed, it likely will return.
Does this code relate to other problems?
Yes, it can affect systems like ABS and traction control, as they rely on steering input.
