Steering Position Sensor Malfunction
The steering position sensor is malfunctioning or sending incorrect signals.
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 tells the computer which way the steering wheel is turned. If it's broken, the computer can't tell the position accurately, which can affect steering control and stability.
What the computer is actually seeing
The computer expects to see a voltage signal that changes smoothly with steering input. Typically, the voltage should vary between 0.5V (full left) and 4.5V (full right) proportional to steering angle.
What a healthy reading looks like
Expected voltage readings from the steering position sensor range from 0.5V to 4.5V based on steering angle.
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 between the steering position sensor and the Power Steering Control Module. Look for frays, corrosion, or disconnections. Is everything intact? -> If yes, go to step 2. If no, repair the wiring/connectors and retest.
- 22. Measure the voltage output of the steering position sensor with a multimeter while turning the steering wheel. Are voltage readings between 0.5V and 4.5V as expected? -> If yes, the sensor may still be fine. If no, proceed to step 3.
- 33. Replace the steering position sensor and retest. Is the fault code cleared after replacing? -> If yes, the problem is solved. If no, proceed to step 4.
- 44. Check for software updates or recalibration needs for the power steering control module. Has the issue been resolved? -> If yes, you're good. If no, further diagnosis of the control module may be required.
Common causes
- Faulty steering position sensor
- Wiring issues (shorts or opens)
- Corroded or loose connectors
- Calibration issues after repairs
- Faulty power steering module

Frequently asked questions
Can I still drive the vehicle with this code?
Yes, but steering may feel less responsive. It's better to fix soon for safety and handling.
Will this code come back after clearing?
If the underlying issue is not resolved, such as a faulty sensor or wiring problem, it will likely return.
Why does this code appear with other steering-related codes?
These codes often share components like the sensor wiring or the power steering control module, which can cause multiple faults.
