C0031 on Lincoln
Left front wheel speed sensor circuit fault (Ford and Lincoln)
Severity: Severity not verified — if the car runs badly, have it inspected
The sources describe the fault and the warning lamps but not how safe it is to drive; ABS and stability control are safety-critical, so have it checked.
It gets more serious if:
- Stop: The red brake warning lamp comes on, the pedal feels soft or low, or steering assist is lost along with the ABS lamp.
