Steering Angle Sensor Performance
The steering angle sensor is malfunctioning or reporting incorrect data.
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 monitors how far and fast you turn the steering wheel. If it fails, your vehicle's stability systems won't know what's happening, which can affect control and safety.
What the computer is actually seeing
The vehicle's computer expects input from the steering angle sensor to be within a specific range while you're steering. If the signal deviates from the expected range or fluctuates erratically, it will trigger the code.
What a healthy reading looks like
The expected voltage output from the steering angle sensor should be between 0.5V and 4.5V when the wheel is turned from lock to lock, with a smooth transition throughout.
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 wiring damage or corrosion at the steering angle sensor connector.
- 2Verify the sensor's voltage output with a multimeter; it should be between 0.5V and 4.5V when steering.
- 3Inspect for any DTCs related to other systems (ABS, ESC) that may affect the steering angle sensor operation.
- 4If everything checks out but the code persists, try recalibrating the steering angle sensor using a scan tool.
Common causes
- Wiring issues at the connector for the steering angle sensor
- Faulty steering angle sensor
- Corrosion or dirt on the connector pins
- Software calibration issue in the vehicle's control module

Frequently asked questions
Is it safe to drive with this code?
Moderate caution is advised; the vehicle may have reduced stability control and ABS, which can affect safety.
Will this code come back after clearing?
Yes, if the underlying issue isn't fixed or the sensor is still faulty, the code is likely to return.
Why does this code show up with other codes?
It often pairs with other stability-related codes because the steering angle sensor is critical to systems like ABS and traction control.
