Steering Angle Sensor Fault
There's a problem with the steering angle sensor's signal or position.
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 position of your steering wheel. If it fails, the system can't track how much steering input you're giving it, which can mess with things like stability control.
What the computer is actually seeing
The computer expects a specific voltage or signal pattern from the steering angle sensor. If it sees a reading that doesn't match the expected range, like a steady voltage when it should be changing based on steering input, it throws a fault code.
What a healthy reading looks like
The steering angle sensor typically should send a variable voltage signal between 0.5V (full left) to 4.5V (full right) while 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.
- 1Inspect the wiring and connectors for damage or corrosion, especially around the steering column.
- 2Use a multimeter to check the voltage output of the steering angle sensor while turning the steering wheel. Voltage should vary from 0.5V to 4.5V.
- 3If the voltage readings are outside of expected values, replace the steering angle sensor.
- 4If readings are normal, check for software updates or other system faults that might influence the sensor's operation.
Common causes
- Faulty steering angle sensor
- Wiring issues (shorts, opens)
- Poor connections or corroded connectors
- Steering column movement has affected sensor alignment

Frequently asked questions
Is it safe to drive with this code present?
It's drivable but can affect stability control systems, so fix it soon.
Will the code come back after I reset it?
If the underlying issue isn't fixed, yes, it will return.
Why is this code showing alongside stability control codes?
They share the same input data; if the steering angle sensor fails, it affects stability control performance.
