1 vehicles · 1 makes · $180-$900 repair
Most Reported On
C0223 is an OBD-II diagnostic trouble code meaning “Right Front Wheel Speed Sensor Signal Erratic.” This code means the ABS module is receiving a signal from the right front wheel speed sensor, but the signal is erratic or inconsistent rather than smooth and steady. An erratic signal often points to a mechanical issue — like a damaged tone ring, debris in the sensor gap, or a wobbling wheel bearing — rather than a pure wiring fault. The module may disable ABS, traction, and stability control and illuminate the warning lights. Driving on very rough terrain can occasionally trigger this code even when the system is healthy. This code is most commonly reported on 2000-2006 GMC Yukon XL, with repair costs ranging from $180 to $900.
