P0BF0 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0BF0 can be explained as Drive Motor “A” Phase W Current Sensor Circuit High. 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. Then the permanent magnets provided in the rotor would be pulled in the direction of rotation, generating torque. The generated torque would be proportional to the amount of current. The system would control the MG2 speed by regulating the frequency of the alternating current. The system would properly control the ting magnetic field and the angle of the rotor magnets in order to generate high torque in an organized manner, even at greater speeds.

The drive motor generator power inverter control module would monitor and regulate the high voltage system as well as drivetrain constituents. This module would run self-checks to safeguard that it is capable of properly performing its needed functions. Now if the error would be detected, then the P0BF0 trouble code would start indicating.

What causes this problem with the Drive Motor “A” Phase W Current Sensor Circuit High?

• Defaults in the hybrid vehicle motor assembly
• Hybrid vehicle motor assembly harness might be opened or shorted
• Hybrid vehicle motor assembly circuit might have bad electrical connection

1. Inverter Cooler Pump - As part of the cooling system, the inverter coolant pump translates high-voltage direct current generated by hybrid batteries into alternating current for the motor to keep the system at the proper operating temperature. Thus, if the cooler pump if faulty, it should be replaced immediately.
2. Hybrid Battery - A hybrid battery that has dead traction can be very problematic. It can result in a delayed or instant release of gases that are toxic or flammable. We recommend you to change it instantly without taking the risk of touching it as it may lead to a shock.
3. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
4. Battery Temperature Sensor - A symptom commonly associated with a failing battery temperature sensor is an engine that surges during operation. The battery temperature sensor helps the system continuously adjusts the system voltage, and if it fails, this process may be disturbed. Thus, replace it now!
5. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
6. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So, it is very important to replace the defective electronic control unit with us at equitable prices.
7. Diagnostic Tool - Use high grade diagnostic tools and equipment to resolve OBD code error. Buy new tools and equipment form us now!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0BF0 code to be stored:

After verifying the P0BF0 code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components, especially looking for some issues in the drive motor “A” phase W current sensor circuit. Any issues should be repaired, and the code should be cleared from the system.

If the code reappears after a retest, the mechanic should then move on to performing voltage tests and resistance tests on the sensor, and comparing the information to the manufacturer’s specifications.

If the readings are within the correct limits, then the sensor needs to be replaced. However, if the readings are not within the correct limits, then the issue lies elsewhere. The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.

Common Mistakes When Diagnosing The P0BF0 Code

• There can be a failure in the drive motor generator power inverter control module
• Flaws in the wiring
