Steering Angle Sensor Range/Performance Problem
The steering angle sensor is not providing a valid signal to the control module.
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 how much the steering wheel is turned. If it’s out of range, the computer can’t tell if the wheels are pointing where they should be.
What the computer is actually seeing
The control module expects a voltage that changes as the steering wheel turns. If it sees a voltage that’s too high or too low, or inconsistent changes, it triggers the code.
What a healthy reading looks like
Steering angle should typically range from -40° to +40° with a corresponding voltage output of 0.5V to 4.5V.
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 the wiring and connectors to the steering angle sensor for damage or corrosion. Repair if necessary.
- 22. Measure the voltage at the sensor. Ensure it shows between 0.5V and 4.5V while turning the wheel.
- 33. If voltage is out of range, inspect the sensor. Swap it with a known good unit to see if the code clears.
- 44. If the code persists with a new sensor, check the vehicle's steering column for binding or misalignment.
- 55. Finally, verify that the sensor is calibrated properly if any components related to steering have been replaced.
Common causes
- Faulty steering angle sensor
- Wiring issues or connector problems
- Calibration needed after steering component replacement

Frequently asked questions
Is it safe to drive with this code?
It's best to get this fixed soon. It may affect traction control, which can be a safety issue.
Will the code come back after repair?
If the cause is correctly identified and fixed, the code shouldn't return.
Why does this code sometimes pair with traction control lights?
Both systems rely on accurate steering information, so a problem in one can trigger warning lights in the other.
