P0BAE - OBD Trouble Code

<<See All OBD Codes

Is the car’s Check Engine Light illuminated? Is the car engine stalling and sometimes not starting? Is there a loss of power and acceleration with affected fuel economy? Thus, there might be an issue with the hybrid battery and circuit indicating OBD code P0BAE error in the ECM/PCM.

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 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 Hybrid Battery Voltage Sense "X" Circuit?

• Hybrid Battery Pack Issue
• Hybrid Battery Pack harness damaged
• Hybrid Battery Pack circuit and connection problem

1. Car Battery - Faulty car battery can have the problem of overheating and fast discharging. Thus, it can affect the motor performance as well as damaged major components. Replace it immediately.
2. Powertrain Control Module - A broken Powertrain Control Module can cause a lot of issues. It can cause wrong OBD error to get stored in the system and affect the functioning of various components, thus affecting the vehicle performance. It would be nice if you get it replaced on time.
3. Inverter Cooler Pump - The inverter cooler pump can also be faulty and not respond to the PCM instructions. This means that even though the temperature sensor and the PCM are working properly, the cooler pump may not work and cause damage to the battery functions. Thus, replace it immediately.
4. Electronic Control Unit - The ECU managed the cooling system to control the battery operating temperatures and thus must be replaced if found faulty. Thus, buy new ECU modules and components form us!
5. Hybrid Drive Cooling Pump - Check for faults in the hybrid battery cooling pump and replace it, if required. If the cooling pump does not function properly, then the battery might not work to its full capacity and can cause serious performance issues.
6. Battery Temperature Sensor - Inspect for faulty battery temperature sensor as it may cause the battery to overheat and not work properly and cause serious physical damages to various starting and charging system components. Thus, replace faulty sensor now!

Well, if you are looking to know about the common symptoms related to this error code P0BAE, we have worked out a small list to help you discover this error code with your vehicle.

Common Symptoms

• The Check Engine Light will be illuminated and the code is set in ECM memory
• The engine could stall or not start when failure is present
• The engine may have a misfire and may buck or jerk while driving for an intermittent connection
• The engine may not start or have low power if it does start

Here are some ways with the help of which you will be able to correct the OBD Code P0BAE.

• Replacing the faulty hybrid battery current sensor
• Replacing a broken wiring and connectors
• Repairing corroded connections to the battery
• PCM and ECU replacement

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of Electric Vehicle Battery Pack, Battery Interface Control Module, battery assembly and a lot more. We are sure that now all your issues would be resolved.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0BAE code to be stored:

• A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes.
• The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur.
• Visual inspection of the wiring and connectors to check for loose connections, corrosion, or shorts is done.
• A specialized tool may be used to test the battery current sensor. Other tests of the hybrid battery and its components may help pinpoint the problem, as well as inspection of the wiring and connectors.
• Disconnect and check the resistance and signal voltage from the battery current sensor.
• If all the components check out, inspect for the fault in the PCM as it can sometimes store wrong OBD code and thus might need replacement or reprogramming.

Common Mistakes When Diagnosing OBD Code P0BAE

Most of the time the battery is immediately replaced without analysing the problem as per the OBD code error. Thus, proper scan tools need to be used to check for the real cause of the problem that may be ECM, wiring issues, fuel system problems and many more parts other than the hybrid battery only. Thus, proper evaluation and remedy is advisable.
