C0658Right Front Wheel Speed Sensor B Circuit/Open
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0658 reports an open in the wiring of right front sensor B, so the module sees no supply current on that channel. Sensor B is the redundant partner found mainly in brake systems built for automated driving; ABS normally keeps running on sensor A, where an open would show as C0506. Audi's patent for such a pair gives each sensor its own data line to the controller, so that one broken line cannot remove both signals, and suggests a passive inductive sensor as the second one because it works without any supply. For the anti-lock function itself, UN Regulation 13-H demands that every electrical fault, external wiring included, lights the yellow warning. Check plug, cable and sensor. No carmaker publishes C0658; GM's old PIP5094 list uses the number for something else.
