Error Code P0BFF: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information with respect to P0BFF, then you are at the right place and keep reading further. Malfunctioning of the high voltage system is known as drive motor “A” current. Two motor control modules and hybrid powertrain control module is present in the drive motor generator power inverter control module. If the flow of current through the motor control module is more, the P0BFF error will be set and the high voltage system will be deactivated.

Rotating magnetic field will be created in MG2, only when the 3-phase alternating current moves through the 3-phase windings of the stator coil. Corresponding to the rotation position and speed of the rotor, the rotation of the magnetic field is handled by the system. As a result, the permanent magnets that are found in the rotor will be pulled towards the direction of rotation by creating more torque. The torque which is created will be almost proportional to the amount of current. The MG2 speed is handled by the system which regulates the frequency of the alternating current. Additionally, the system will correctly control the rotating magnetic field and angle of the rotor magnets so as to produce even more torque in an effective manner during high speed.

What causes this problem with Drive Motor "A" Current?

• The hybrid vehicle motor assembly might be damaged.
• You will see an opening or short-circuit in the hybrid vehicle motor assembly harness.
• The bad electrical connection in the hybrid vehicle motor assembly circuit.

1. Hybrid Vehicle Motor Assembly - Facing troubles with your faulty hybrid vehicle motor assembly? Then it’s high time to get a new converter assembly from PartsAvatar to avoid the P0BFF error code.
2. Hybrid Vehicle Motor Assembly Harness - A faulty hybrid vehicle motor assembly harness will need immediate replacement so that the system functions normally.
3. Engine Control Module - Is the performance of the engine very poor? Does your engine keep stalling very often? Then the ECM might be faulty which needs replacement as soon as possible.
4. Powertrain Control Module - The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P0BFF code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• Blinking of the engine light as well as the warning light of the service engine.

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P0BFF, you will need to undergo the following replacements:

• Replacing the hybrid vehicle motor assembly.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of hybrid vehicle motor assembly, hybrid vehicle motor harness, inverter control module and many more. Now all your problems would vanish within no time.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0BFF code to be stored:

• The reductant compound, in turn, will help to minimize the exhaust gas temperature and/or pressure and noxious gases.
• The exhaust gas temperature sensor is nothing but a 2- wire sensor which is placed in the exhaust downpipe.
• At times, it is wise to leave these type of error codes in the hands of the professionals as there are several other circuits involved.
• See if there are any clutch materials or other debris by removing the transmission pan if the fluid has burnt smell.
• Blocked hydraulic passage, faulty pump, defective shift solenoid or a damaged electronic pressure regulator are some of the reasons for low pump pressure
• ve the transmission pan, if the fluid smells burnt and look for clutch materials and other debris.
• Low pump pressure might likely arise due to clogged hydraulic passages, a faulty pump, faulty shift solenoids, or a faulty electronic pressure regulator
• With just one sign for a faulty gasket, it is not sufficient to prove that the gasket is faulty, but you will need multiple symptoms to prove the failure of a gasket.
• Whenever you face these symptoms make sure to drive your vehicle as little as possible.
• Based on the symptoms, you can either repair or replace the gasket.
• The cost to repair a gasket usually depends on one mechanic to another.
• In modern engines, because of the location of a gasket and the amount of labor involved, it’s quite expensive to replace a faulty gasket.
• A P0BFF error code is generally related to a faulty sensor, but replacing them will not solve the original issue.
• The error is most likely caused by the system which the sensor monitors but it can even be caused by the wires which connect the sensor itself.

Common Mistakes When Diagnosing the P0BFF Code

• Damaged inverter control module.
• An issue might arise due to faulty wires.
