C061FVariable Effort Steering Actuator Control Circuit Performance
- Generic OBD-II code · Chassis
- How the car detects it
- C061F covers an actuator circuit that is electrically intact but does not behave as commanded: the current does not follow the request, or the expected change in effort fails to show up. In Magnasteer the coil runs from about −3 A to +3 A, and the current reverses around mid speed, so tracking errors appear as wrong feel in town or on the highway. The Steering Solutions patent stresses that the magnetic null must line up with the valve's centre for the gear to work properly; a later variant without permanent magnets only raises effort with speed. Coil heating, a sticky valve or a damaged magnet ring fit this code. GM's scan tool can run a function test that sweeps the current. No maker publishes C061F.
- What you may notice
- Steering effort wrong for the speed or changing unexpectedly
- Pull to one side with no alignment fault
- Steering warning on some vehicles
- Likely causes
- PossibleMagnetic null shifted from valve centre, damaged magnet ring

- PossibleHigh resistance in connector or wiring limiting coil current
- RareWrong or missing vehicle speed input to the controlling module
