Steering Wheel Position Sensor Range/Performance Problem
This code indicates a problem with the steering wheel position sensor performance.
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 wheel position sensor detects how far and in what direction you're turning the wheel. If it sends incorrect data to the vehicle's computer, the system may not respond properly, affecting things like stability or traction control.
What the computer is actually seeing
The vehicle’s computer expects the steering angle to change smoothly within a specific range. If it detects that the angle is outside this expected range for more than a set period (e.g., over 45 degrees in less than 200 milliseconds), it triggers this code.
What a healthy reading looks like
Expected values for the steering sensor should be within -540 to +540 degrees with smooth transitions; rapid changes outside this range will trigger faults.
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 visible wiring damage or corroded connectors at the steering angle sensor. If found, repair or replace the damaged parts. Decision: Repair/wire or Replace connector.
- 2Using a scan tool, clear the fault codes and test drive the vehicle. Monitor the steering angle reading while turning the wheel. Decision: Monitor for codes or not.
- 3Inspect the steering wheel position sensor’s output voltage while turning the wheel. Expected voltage should smoothly change between 0.5V and 4.5V. Decision: In-spec or Out-of-spec.
- 4If the sensor reads out-of-spec, replace the steering angle sensor. Decision: Replace or Further test for stability issues.
Common causes
- Faulty steering angle sensor
- Wiring issues or corroded connectors
- Faulty steering rack
- Issues with the vehicle's stability control system
