P0B86 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0B86 can be defined as Hybrid Battery Voltage Sense "P" Circuit. If the powertrain control module would detect a variation in the voltage coming from the hybrid battery that is outside the parameters set by the automobile manufacturer, then it would flash OBD code P0B86 in the system. This can cause vehicle going into limp mode and check engine light getting illumination.

We learn more by looking for the answer to a question. That’s the reason why we are here to provide you the answers for all your questions. The hybrid/electric vehicle battery pack contains numerous cells which are welded together in parallel. The battery energy control module monitors the voltage from the various cell groups through the battery interface control modules. The hybrid battery interface control module encodes the voltage reading and transmits it to the battery energy control module through the battery control harness which will determine when a fault condition is present and then the PCM will store the OBD code P0B86 is the system.

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

• The hybrid/electric vehicle battery pack might be damaged
• Malfunctioning hybrid/electric vehicle battery interface control module

1. Powertrain Control Module - The P0B86 code can also arise due to some issues in Powertrain Control Module. So it is advised to replace them as soon as possible.
2. Car Battery - Do you remember when was the last time you got your Car Battery checked up? A damaged Car Battery can cause a lot of issues like displaying P0B86 code.
3. Engine Control Module - Engine Control Module is an important car part which should never be neglected. May be there is some fault in it due to which P0B86 code may start flashing.
4. Car Exhaust System Parts - Are your Car Exhaust System Parts damaged or broken? Don’t worry as we have solutions for all your problems.
5. Hybrid Battery - Defective car Hybrid Battery can be a major reason why P0B86 code depicts. So make sure to replace it online so that you don’t have to face any further issues.
6. Auxiliary Battery Relay - Auxiliary Battery Relay is an important auto part. Take care of it and you can rely on us to purchase best quality Auxiliary Battery Relay online.
7. Exhaust Manifold - Everything is okay with the Hybrid Battery and still OBD code P0B86 triggering? Then there must be some defects in Exhaust Manifold. Replace them as soon as possible.

Willing to know some common symptoms of OBD Trouble Code P0B86? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check engine light can start flashing up
• 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

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0B86:

• It is essential to restore the flawed engine control module
• Repair or replace the quirky hybrid/electric vehicle battery interface control module
• Make sure to mend the faulty hybrid/electric vehicle battery pack
• Carefully adjust the faults in the hybrid battery
• It is necessary to perform proper service of the unsound exhaust manifold

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

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 sometime store wrong OBD code and thus might need replacement or reprogramming.

Common Mistakes When Diagnosing The P0B86 Code

• Some issues related to the high voltage battery assembly
• Failure in the high voltage battery connection
• Issues related to the wiring
