Invalid Data Received from Steering Position Sensor
The steering position sensor is reporting invalid data to the vehicle computer.
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 position sensor measures the angle of the steering wheel. If it sends bad data, the computer can't figure out how far you're turning the wheel, which could affect handling and safety.
What the computer is actually seeing
The vehicle computer expects voltages corresponding to the steering angle, usually between 0.5V (full left) to 4.5V (full right). When the voltage deviates outside this range, or does not change appropriately, an invalid data flag sets.
What a healthy reading looks like
Voltage should vary from 0.5V to 4.5V, proportional to steering angle. Watch for smooth transitions between 1.5V (center) to 3.5V (1/4 turn either way).
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 battery voltage; it should be between 12.4V and 12.6V with the engine off. Is it within range?
- 22. Inspect wiring and connectors of the steering position sensor for damage or corrosion. Are they intact?
- 33. Using a scan tool, check live data for the steering position sensor. Is the voltage within 0.5V to 4.5V during turns?
- 44. If voltage is out of range, swap the steering position sensor with a known good one and retest. Did the fault clear?
- 55. If the fault persists, check the steering column module for faults or test with a different module. Did the problem resolve?
Common causes
- Faulty steering position sensor
- Wiring issues or connector corrosion
- Failed steering column module
- Battery voltage issues affecting sensor operation

Frequently asked questions
Is it safe to drive with this code?
It's drivable but steer with caution; handling may be affected.
Will this code come back after resetting?
If the underlying issue isn't fixed, it will likely return.
What if my steering feels fine?
The sensor may still be faulty despite normal steering feel; don't overlook it.
