What does code C0654 mean?

Q: What does code C0654 mean?

Left Front Wheel Speed Sensor B Circuit High. This code means the antilock braking system (ABS) module has detected an abnormally high voltage on the signal circuit for the left front wheel speed sensor, which is the sensor that reports how fast that wheel is turning. The module compares the voltage it receives against the expected range and sets the code when the signal stays above the high threshold for a set period, so the ABS and often traction control are disabled until the fault is repaired.
