C0725: Electric Power Steering Motor Circuit
The EPS assist motor circuit reports an electrical fault.
What C0725 means
C0725 is a generic OBD-II chassis code in the steering group. In plain English: the computer found an electrical fault in that circuit: an open, short or bad connection, or a failed component.

Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- 01Motor winding openMost likely
- 02Short to ground in motor wiringPossible
Can I drive with C0725?
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 C0725
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just C0725. 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
Test the circuit
Inspect the wiring and connector at the eps motor and eps control module for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Motor winding open; short to ground in motor wiring. 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.
