The code indicates an open circuit in the electrical signal from the right front wheel speed sensor B to the vehicle's control module. It means the sensor is not sending a valid speed signal.
The sensor's internal circuit can break or become damaged, causing an open circuit.
Exposed, corroded, or broken wires and poor connector contact can interrupt the signal.
Bearing damage can affect the sensor's mounting and cause intermittent or open signals.
A problem within the module's input circuit can mimic an open sensor, though less common.
A rare failure of the PCM's sensor input circuitry could cause the code, but it is unlikely.
Replacing the PCM is rarely necessary; the issue is usually a bad sensor or wiring problem.
It may cause minor fuel inefficiencies, but the primary impact is on ABS and traction control systems.
You can drive it, but ABS and traction control may be disabled, so exercise caution, especially on slippery surfaces.
Typically 30‑60 minutes for a trained technician to swap the sensor and verify proper operation.
