What does code C0659 mean?

Q: What does code C0659 mean?

Right Front Wheel Speed Sensor B Range/Performance. C0659 means the antilock braking system (ABS) control module has detected an abnormal signal from the right front wheel speed sensor circuit, specifically a range or performance fault rather than a total loss of signal. The computer compares that wheel's speed to the other three and flags the code when the signal is erratic, intermittent, or outside the expected voltage or frequency window.
