C0050 on RAM
Right Rear Wheel Speed Sensor Circuit
C0050 on RAM vehicles indicates right rear wheel speed sensor circuit. Au7o has documented this code across 1 RAM model — most commonly on 3500. 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. Typical repair costs on RAM range from $300 to $700, depending on the specific model and root cause.
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)
C0050 on RAM by Model
RAM 3500(1 issue)
- Front Hub Bearing Failure Under Heavy Load2010-2025
The front hub bearings (wheel bearing assemblies) in the RAM 3500 fail prematurely, particularly on trucks that carry heavy loads in the bed or tow heavy trailers. The factory hub bearings are adequate for unloaded driving but wear rapidly under sustained heavy GVWR/GCWR conditions. 4x4 models are more affected due to the additional stress of the front axle components. Bearing failure typically occurs between 60,000-100,000 miles on heavy-use trucks.
