P0B52 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0B52 can be described as Hybrid Battery Voltage Sense "E" Circuit High. There are 288 cells in the hybrid/electric vehicle battery pack. There is a group of three cells which are properly welded together in a parallel direction. The hybrid/EV battery pack assembly contains 96 cell groups in total. They are then connected together in series electrically. Every specific cell group is rated at 3.7 V for a nominal system voltage of 355 V direct current. The battery cells are grouped in the form of three sections.

Don’t worry if P0B52 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Hybrid Battery Voltage Sense "E" Circuit High?

• Unusable hybrid/electric vehicle battery pack
• Quirks in the hybrid/electric vehicle battery interface control module
• There can be inoperative car battery
• Powertrain control module or engine control module might be flawed

1. Auxiliary Battery Relay - It is an important auto part which needs full care. A faulty Auxiliary Battery Relay can be a reason behind the flashing up of P0B52 code.
2. Hybrid Battery - Do you remember when was the last time you got your car Hybrid Battery checked up? A dirty Hybrid Battery can cause a lot of issues like displaying P0B52 code.
3. Engine Control Module - Poor Engine Control Module can cause a lot of difficulties, so why not get it replaced at time?
4. Car Exhaust System Parts - Are there some faults in your Car Exhaust System Parts? Don’t waste time and get them replaced or else P0B52 code can turn up.
5. Car Battery - OBD Code P0B52 can appear because of faulty Car Battery. Purchase high grade Car Battery online.
6. Exhaust Manifold - Everything is fine with Car Battery and still P0B52 code triggering? Then you must get your Exhaust Manifold checked and then all your issues would be solved.
7. Powertrain Control Module - There can be some issues with the Powertrain Control Module due to which you may see P0B52 code appearing over and over again. Visit us to buy best quality PCM online.
