C0712: Power Steering Position Sensor Range/Performance
The power steering control module has detected that the rack or column position signal is out of range or implausible. Steering assist may be reduced.
What C0712 means
C0712 is a generic OBD-II chassis code in the steering group. In plain English: the signal is within electrical limits but doesn’t make sense compared with other readings, so the part or system isn’t performing as expected.

Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- 01Steering position sensor failedMost likely
- 02Sensor calibration required after servicePossible
- 03Sensor element aged beyond calibration windowLess likely
Can I drive with C0712?
Drive carefully and get it checked soon.
Steering assist may drop out, making the wheel heavy at low speed. Avoid driving if steering becomes very heavy or erratic.
Why we rate it urgent
- Steering assist may be reduced or lost
- Usually lights the ABS, traction or stability warning instead of the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose C0712
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just C0712. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Power steering module, Steering position sensor, Sensor wiring) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Steering position sensor failed; sensor calibration required after service; sensor element aged beyond calibration window. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

C0712 FAQ
What does C0712 mean?
C0712 means “Power Steering Position Sensor Range/Performance”. The power steering control module has detected that the rack or column position signal is out of range or implausible. Steering assist may be reduced.
Is C0712 serious? Can I keep driving?
We rate C0712 as urgent severity. Drive carefully and get it checked soon. Steering assist may drop out, making the wheel heavy at low speed. Avoid driving if steering becomes very heavy or erratic.
What causes C0712?
The most common causes, from most to least likely: Steering position sensor failed; Sensor calibration required after service; Sensor element aged beyond calibration window. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix C0712?
Typical labor is about $65–$375 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix C0712 myself?
DIY difficulty is moderate. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will C0712 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
