Steering Position Sensor Performance
Issue with the steering position sensor's performance detected by the vehicle's control module.
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 computer is saying the steering position sensor isn't working right, which affects the stability and handling of the vehicle.
What the computer is actually seeing
The vehicle's control module (ECM) monitors the steering position sensor to determine the angle of the steering wheel. If the sensor sends signals that are out of expected range or inconsistent, it triggers code C0572.
What a healthy reading looks like
The steering position sensor should output a voltage range between 0.5V to 4.5V at a steering angle of -90 to +90 degrees. Check for a linear response across the full range of motion.
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 for the steering position sensor. Look for any visible damage, corrosion, or loose connections.
- 22. Measure the voltage output from the steering position sensor with the ignition on and the steering wheel straight. You should see a value between 1.5V and 2.5V.
- 33. If the voltage is outside the expected range, disconnect the sensor and check the continuity of the wiring back to the control module.
- 44. Reconnect the sensor and manually turn the steering wheel side to side while monitoring the voltage output. It should change smoothly throughout the range.
- 55. If the sensor is faulty, replace it and reset the code. If the problem persists, check for control module updates or faults in the control module itself.
Common causes
- Wiring issues (frayed or shorted wires)
- Faulty steering position sensor
- Poor connector connections
- Control module software issue

Frequently asked questions
Is it safe to drive with this code?
You can drive the vehicle, but be cautious as handling may be affected, especially during sharp turns.
Will this code come back after I clear it?
If the underlying issue is not fixed (like a bad sensor or wiring), it will likely return after some driving.
Why is this code showing when I have clean steering response?
Sometimes, it can indicate a sensor that’s not responding within the expected range even if it feels okay; testing is crucial.
