C0050 on Lincoln
Right Rear Wheel Speed Sensor Circuit
C0050 on Lincoln vehicles indicates right rear wheel speed sensor circuit. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. This is a brake/ABS-system code. The right rear wheel speed sensor reports how fast that wheel spins so the anti-lock brake, traction control, and stability systems can do their job. C0050 means the ABS module detected an electrical fault in the right rear wheel speed sensor circuit — an open, short, or an erratic/out-of-range signal. This usually turns on the ABS and traction/stability warning lights and may disable those features, though standard braking remains available.
Common Causes of C0050
- •Failed right rear wheel speed sensor
- •Damaged, corroded or disconnected sensor wiring/connector
- •Damaged or rusty tone/reluctor ring (missing or clogged teeth)
- •Excessive air gap between sensor and tone ring
- •Wheel bearing wear affecting an integrated sensor
- •Moisture or corrosion in the connector
- •Faulty ABS control module (less common)

- Front Wheel-End Hum or Grind - Bearing Diagnosis Before Hub Selection2020-2022
A speed-related hum, growl, grind, vibration, or wheel-end play can be consistent with a wheel bearing, but tire tread, wheel damage, brakes, axle or CV joints, driveline components, and other rotating parts can sound similar. The reviewed evidence does not establish a Lincoln Aviator-wide premature front-hub defect or a reliable failure mileage. A bearing diagnosis must identify the corner and drivetrain configuration before any hub is selected.
