P0BF6 Code - Drive Motor 'B' Phase V Current Sensor Circuit Range/Performance

Quick Answer

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in MG2. Common causes include Faulty Hybrid Vehicle Motor Assembly, Hybrid Vehicle Motor Assembly harness is open or shorted, Hybrid Vehicle Motor Assembly circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0BF6 Description

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in MG2. The system controls the rotation of the magnetic field in accordance with the rotating position and speed of the rotor. As a result, the permanent magnets provided in the rotor are pulled in the direction of rotation, generating torque. The generated torque is almost proportional to the amount of current. The system controls MG2 speed by regulating the frequency of the alternating current. Furthermore, the system properly controls the rotating magnetic field and the angle of the rotor magnets in order to generate high torque in an efficient manner, even at high speeds.
