C0050 on Kia
Right Rear Wheel Speed Sensor Circuit
C0050 on Kia vehicles indicates right rear wheel speed sensor circuit. Au7o has documented this code across 1 Kia model — most commonly on Rio. 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)
