Guide To P0BFD OBD Error Code Solutions

<<See All OBD Codes

If you find the powertrain or engine control module to be faulty, then there is a high chance that the P0BFD error is stored in the vehicle. The high voltage system which does not function properly is known as the drive motor "A" phase U-V-W current sensor correlation. The drive motor generator power inverter control module has two motor control modules and hybrid powertrain control module. As the two motor control modules are tied together, the current which passes through the module will be the same. If not so, the P0BFD error will be set and the high voltage system will be disconnected.

You will notice that a rotating magnetic field is created in MG2 as the 3-phase alternating current passes through the 3-phase windings of the stator coil. The rotation of the magnetic field is controlled by the system corresponding to the rotating position and speed of the rotor. As a result, the permanent magnets that are available in the rotor will be pulled, towards the direction of rotation, producing more torque. The produced torque will almost e proportional to the amount of current. The system will operate the MG2 speed by producing the frequency of the alternating current. Also, the system will rightly operate the rotating magnetic field and the angle of the rotor magnet so as to produce more torque in a proper manner even when the speed is high.

What causes this problem with Drive Motor "A" Phase U-V-W Current Sensor Correlation?

• Defective hybrid vehicle motor assembly.
• The hybrid vehicle motor assembly harness might have an opening or short circuit.
• The hybrid vehicle motor assembly circuit might have a weak electrical connection.

1. Hybrid Vehicle Motor Assembly - If you want to avoid the P0BFD error in the vehicle, then the damaged hybrid vehicle motor assembly must be fixed by getting a new one from PartsAvatar.
2. Hybrid Vehicle Motor Assembly Harness - The faulty hybrid vehicle motor assembly harness has to be fixed for the vehicle to function normally. 
3. Engine Control Module - Does your car jump start on reverse polarity? It is an indication of damaged ECM. Repair / replace it soon to avoid P0BFD error.
4. Powertrain Control Module - If you find the check engine light on the display dashboard, then the PCM is faulty. Replace it as soon as possible to avoid the P0BFD error.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0BFD here:

Common Symptoms

• The service engine warning light and engine light will keep blinking and stays on.

Here are some ways with the help of which you will be able to correct the OBD Code P0BFD

• Replacing the faulty hybrid vehicle motor assembly.
• Changing the engine control module/ powertrain control module which is damaged.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high-grade hybrid vehicle motor assembly, hybrid vehicle motor assembly harness, inverter control module and a lot more for our precious customers.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0BFD code to be stored:

• The exhaust after-treatment fuel injector is basically placed directly in the diesel particulate filter or else the catalytic converter and it is controlled electronically with the help of a dedicated exhaust after treatment fuel injector controller which helps in conjunction with the PCM.
• This is not similar to other error code. So, it is best to leave it to the professionals as you can see there are several circuits involved in this diagnostic process.
• If you find the fluid to be smelly with a burnt smell, take away the transmission pan and see for the presence of clutch materials as well as other debris.
• Low pump pressure can arise due to several other reasons like clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator.
• You will hear banging and grouching noises due to the engine mountings that are broken.
• There are usually 2 types of mounting - one is placed centrally, very near to the bottom of the block and the other one is placed a little high, on the inner side of the wings or chassis members.
• This type of error code usually refers to the camshaft (cam) timing.
• Over- retardation of the cam timing will make the check engine light to be illuminated and the error code will be set in the vehicle.

Common Mistakes When Diagnosing the P0BFD Code

• An issue with the electrical wires.
• Defective inverter control module.
