Steering Angle Sensor Circuit Range/Performance Problem
The steering angle sensor is reporting a value outside of its 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 tracks the position of the steering wheel, and if it reports values that the vehicle's computer sees as incorrect or out of bounds, it throws this code.
What the computer is actually seeing
The computer looks at the voltage signal from the steering angle sensor—typically 0.5V (straight) to 4.5V (full turn) in a 5V reference system—but gets a signal that's too low or high.
What a healthy reading looks like
Expected readings from the steering angle sensor should range between 0.5V to 4.5V, reflecting the wheel's position; anything outside this range triggers the fault.
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 of the steering angle sensor for damage or corrosion. Repair or replace as necessary. Decision Point: If wiring and connectors are good, proceed to the next step; if not, fix and retest.
- 22. Check the steering angle sensor with a multimeter. You should see a voltage signal between 0.5V and 4.5V as you turn the steering wheel. Decision Point: If voltages are out of range, replace the steering angle sensor; if within range, proceed to the next step.
- 33. Verify that the steering angle sensor is calibrated correctly. Use a scan tool to reset or recalibrate if necessary. Decision Point: If recalibration resolves the issue, clear the code; if it doesn't, further diagnostics may be needed.
Common causes
- Faulty steering angle sensor
- Corroded or damaged wiring
- Loose or damaged connectors
- Calibration issue after alignment
- Software glitches in the control module

Frequently asked questions
Is it safe to drive with this code?
It’s considered moderate severity; steering could be less responsive, so it's best to fix it soon.
Will the code come back after clearing it?
If the underlying issue isn't resolved, yes, it will likely return.
Why does this code appear after an alignment?
If the steering angle sensor isn't recalibrated after an alignment, the values can read incorrectly.
