Frequently asked questions
What does C0050 mean on a Chrysler?
C0050 stands for "Right Rear Wheel Speed Sensor Circuit." 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. On Chrysler it is documented across 1 model: 300.
