C0725Electric Power Steering Motor Circuit
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0725 has no public documentation; the publicly available J2012 tables, NHTSA bulletins and maker indexes leave it out. Carmakers file assist motor faults elsewhere: GM uses C0475, including symptom 64 for a detected slip in the motor circuit (bulletin PIT5213B), and Stellantis C1592, which the 2019 Jeep Cherokee could log as a general electrical failure and which a software flash addressed under bulletin 08-034-20, sometimes together with a MIL. The motor is usually a brushless machine fed by a power stage; NXP describes control units that measure rotor position and the current in each phase and set PWM duty cycles through field-oriented control. A circuit fault here means a phase, the power stage or the wiring does not behave as commanded, so the module cuts or reduces assist and steering becomes heavy.
