Steering Position Sensor Fault
There’s an issue with the signal from the steering position sensor.
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 much you’re turning the steering wheel and sends that information to the computer. If it’s not working, the computer can’t tell where the wheels are pointing, which can affect your ability to steer properly.
What the computer is actually seeing
The computer expects a voltage signal between 0.5V and 4.5V from the steering position sensor, depending on the steering angle. If the signal stays too high or too low, or there’s no signal at all, the code sets.
What a healthy reading looks like
The voltage from the steering position sensor should vary, typically ranging from 0.5 volts (full left) to 4.5 volts (full right) with a centered position around 2.5 volts.
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.
- 1Inspect the wiring and connectors for damage, corrosion, or loose connections. If found, repair or replace as necessary. Decision: Is wiring intact? Yes – go to next step. No – repair/replace wiring.
- 2Measure voltage at the steering position sensor connector with the steering wheel centered. Expected voltage is around 2.5V. Decision: Is voltage correct? Yes – go to next step. No – replace sensor or fix wiring.
- 3Check the vehicle's alignment and ensure the steering sensor is calibrated correctly. Refer to the service manual for calibration procedures. Decision: Is the sensor calibrated? Yes – code may need to be cleared. No – calibrate the sensor.
Common causes
- Damaged wiring or connectors to the sensor
- Faulty steering position sensor
- Calibration issue with the steering sensor
- Corrosion in the connector terminals

Frequently asked questions
Is it safe to drive with this code?
It can be drivable, but steering response may be impaired, so it's best not to drive until fixed.
Will the code come back after clearing?
It may come back if the underlying cause isn't fixed.
Why does this code pair with other steering codes?
These codes often stem from related systems that monitor steering position and assist.
