What does code C065A mean?

Q: What does code C065A mean?

Right Front Wheel Speed Sensor B Circuit Low. C065A indicates that the antilock braking system (ABS) control module has detected an abnormally low voltage or current on the right front wheel speed sensor's 'B' circuit, which is typically the signal return or secondary wire in a two-wire sensor design. The module sets this code when the electrical signal from that sensor falls below the expected threshold, preventing reliable wheel speed data for that corner.
