Error Code P0BF3: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0BF3 can be described as Drive Motor ‘B’ Phase U Current Sensor Circuit Low. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

There would be a generation of a rotating magnetic field in MG2 when three-phase alternating current would flow through the three-phase windings of the stator coil. The system would control the rotation of the magnetic field in accordance with the rotating position and speed of the rotor.

What causes this problem with the Drive Motor ‘B’ Phase U Current Sensor Circuit Low?

• Malfunctioning hybrid vehicle motor assembly
• Hybrid vehicle motor assembly harness might be unlocked
• Hybrid vehicle motor assembly circuit might have bad electrical connection

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Hybrid Battery - Faulty hybrid battery may overheat or discharge quickly, causing drivability issues. It can affect the acceleration and throttle response and can also cause damage to various parts. Replace the faulty hybrid battery now!
3. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
4. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
5. Diagnostic Tool - Find high grade diagnostic tools to detect the OBD error code from us. Visit us today to grab amazing deals.
6. Battery Temperature Sensor - Faulty temperature sensor can misinterpret the battery temperatures which can result in battery overheating and leakages inside the battery that can harm various components and can be dangerous to driver’s safety also. Thus, replace it at first instance.
