Steering Position Sensor Circuit Range/Performance Problem
This code indicates an issue with the steering position sensor system.
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 how far the steering wheel has turned, like understanding if you're turning left or right. If it sees values that are out of the ordinary, it throws this code.
What the computer is actually seeing
The computer expects the steering position sensor to send a signal that changes smoothly and consistently as you turn the steering wheel. If it sees flat or erratic voltage readings, it sets this code.
What a healthy reading looks like
Normal voltage from the sensor should vary between 0.5V (full left) and 4.5V (full right), typically around 2.5V when centered.
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. Start with a visual inspection of the steering position sensor wiring and connectors. Look for frays, damage, or corrosion. Fix any visible issues.
- 22. Use a multimeter to check the voltage output of the steering position sensor while turning the wheel. Expect a range from 0.5V to 4.5V. If readings are outside this range, replace the sensor.
- 33. If the sensor voltage is within range, check for continuity in the wiring between the sensor and the ECM. Any breaks or shorts mean wiring repairs are needed.
- 44. After repairs, clear the code and take the vehicle for a test drive to verify that the code does not return.
Common causes
- Faulty steering position sensor
- Wiring issues in the sensor circuit
- Loose or corroded connectors
- Faulty steering rack or column
- Software glitch in the ECM/BCM

Frequently asked questions
Can I still drive my vehicle with this code?
Yes, but steering response may be impaired, so drive cautiously and fix soon.
Will this code come back after resetting it?
If the underlying issue isn't fixed, yes, the code will likely return.
Does this code relate to the power steering system?
Indirectly, yes. The steering position sensor helps inform the power steering system how much assist to provide.
