P0ABC OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0ABC can be described as Hybrid Battery Pack Voltage Sense “A” Circuit Low. A lot of different modules are used by the automobiles to run self-checks on the high voltage system. Now if any default is found by any of the modules, then the P0ABC error code would be set. There might be storage of additional codes in other modules.

The P0ABC error code would start indicating that hybrid powertrain control module has set an emission associated hybrid powertrain code. The hybrid powertrain control module would send a message via serial data circuit to the engine control module (ECM) requesting illumination of the Malfunction Indicator Light (MIL). Now when the engine control module would receive this message, then the P0ABC fault code would be triggered up.

What causes this problem with the Hybrid Battery Pack Voltage Sense “A” Circuit Low?

• Defaults in the hybrid battery pack
• Hybrid battery pack harness might be opened or shorted
• Hybrid battery pack circuit might have poor electrical connection
• Malfunctioning battery contactor assembly
• Imperfect battery energy control module

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Hybrid Battery - Faulty hybrid battery may overheat or discharge quickly, causing drivability issues. It can affect the acceleration and throttle response and can also cause damage to various parts. Replace the faulty hybrid battery now!
3. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
4. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
5. Diagnostic Tool - Find high grade diagnostic tools to detect the OBD error code from us. Visit us today to grab amazing deals.
6. Battery Temperature Sensor - Faulty temperature sensor can misinterpret the battery temperatures which can result in battery overheating and leakages inside the battery that can harm various components and can be dangerous to driver’s safety also. Thus, replace it at first instance.

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

• Check for wires and connectors that might be rubbed through, disconnected or loose. It is also important to check the fuse box in your vehicle together with the relay centre that can be found under the hood.
• It is also important to make sure that the fuses are good. Make sure that there is no melted plastic that can cause fire.
• These are some of the major wiring problems that you will encounter with error code P0ABC.
• Carefully inspect the hybrid battery pack voltage sense “A” circuit and make sure to repair or replace it if found faulty.
• Once you have completely checked all the obvious things and still you can’t find the right solution, then you have to begin suspecting either the computer or the sensor.

Common Mistakes When Diagnosing The P0ABC Code

• Flaws in the battery contactor assembly
• Some issues related to the battery energy control module (BECM)
