C0712Power Steering Position Sensor Range/Performance
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- No carmaker is known to document C0712; it is not in the J2012 tables, bulletins or maker indexes searched. The title points to a position input of the power steering whose value is outside the expected band or does not track the other signals. An electric power steering relies on three position measurements: driver torque, the angle of the assist motor and the absolute steering wheel angle; Infineon offers separate angle sensors for the last two. How much an implausible angle hurts is shown by GM bulletin PI0800D for 2013 Equinox, Terrain, Malibu, LaCrosse and Regal: after a botched steering angle alignment the EPS logs a code that will not clear, assist drops to manual after only part of a turn and the car tries to steer to one side at speed. A new calibration or reflash usually follows.
