P0BEC OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0BEC can be explained as Drive Motor “A” Phase V 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.

The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle tovehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

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

• Quirks in the hybrid vehicle motor assembly
• Hybrid vehicle motor assembly harness might be unlocked
• Hybrid vehicle motor assembly circuit bad electrical connection

1. Engine Control Module - ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. Hybrid Battery - Flashing dash lights and engine lights is the first thing a driver may notice. If a deviation in the fuel economy is noticed it is likely due to a failure in the hybrid battery. This may ultimately lead to a fault being triggered in the entire system, requiring a major expensive and time-consuming repair. So, it is advised to get yours changed now from Parts Avatar.
3. Battery Temperature Sensor - If the temperature sensor is faulty, the ECU will not be able to calculate the battery temperatures and the battery can overheat or run cold. Thus it is important that the temperature sensors work properly so that the ECU can control the blower fan to manage the temperatures. Buy new battery temperature sensors form us.
4. Car Battery - The car battery can also be at fault and might have the problem of overcharging and fast discharging. This can cause increased temperatures and can also affect the functioning of various sensors like the speed sensor, temperature sensor and many more. Thus, replace faulty car battery today!
5. Battery Coolant Pump - The battery coolant pump maintains the battery temperatures and optimises the air flow to keep the battery running properly. It the coolant pump gets damaged, then all the components associated with the battery can get damaged and the vehicle may enter fail safe mode to avoid damages. Thus, timely replace faulty coolant pump.
6. Powertrain Control Module - Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
7. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P0BEC error with the help of experienced mechanic. Visit us today!

It is vital 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 P0BEC here:

Common Symptoms

• Appearance of the service engine soon light

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• Rehabilitate the defaults in the hybrid vehicle motor assembly
• The hybrid vehicle motor assembly harness should be restored to working order
• Recondition the non-functioning hybrid vehicle motor assembly circuit

Here are some steps which you should follow in order to diagnose this fault code:

• As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
• After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
• Note down this information as it can clearly help for further diagnosis.
• After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
• He will know that an intermittent condition persists, if the code does not return instantly.
• But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.
• If any of the drive motor “A” phase V current sensor circuit is damaged, the mechanic will replace them quickly.
• Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

Common Mistakes When Diagnosing The P0BEC Code

• Non-Performance of the drive motor generator power inverter control module
• Quirks in the wiring
