Error Code P0B6B: What It Means & What To Do?

<<See All OBD Codes

Error code P0B6B? Don’t know what to do? Well, Parts Avatar has it all! Here’s all that you need to know about the error code P0B6B. This OBD-II code increased fuel consumption is generally referred to as a hybrid battery voltage sense "J" circuit high. A number of mini-batteries connected together can be found in the high voltage battery pack. The code P0B6B is stored by the high voltage control module if the high voltage control module has detected an error with one or more of the battery packs that make up the high voltage battery assembly.

It should be noted that 288 cells are present in the hybrid/electric vehicle battery pack. A bunch of three cells are connected together equally. In the hybrid/EV battery pack assembly, one can find a total of 96 cell groups electrically connected in-series. For a nominal system voltage of 355 V direct current each and every individual cell group is rated at 3.7 V. These battery cells can be found tied together into three sections. Section one is made up of first 90 cells/30 cell groups. Containing batteries ranging from 67 to 96, this section is nearby the cowl. Also, the battery section two can be found behind the section one. Composed of 72 cells/24 cell groups it contains batteries from 43 to 66. The remaining 126 cells/42 cell groups containing batteries from 1 to 42 can be found in the traverse battery section (section number three). Also, these three battery sections consist of individually serviceable parts.

The voltage of the 96 battery cell groups through the four hybrid/EV battery interface control modules is constantly controlled by the battery energy control module. The voltage sense circuits are connected to each individual cell group and these sense circuits can be seen terminating at a connector built in the top surface area of the battery section. The voltage reading is decoded and further transmitted to the battery energy control module through the battery control harness by the hybrid/EV battery interface control module. Both the battery sections one and two have one one hybrid/EV battery interface control module located on it and the battery section three is associated with two hybrid/EV battery interface control modules. The scheme of serviceable components include the hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module.

The presence of the malfunction is notified by the battery energy control module. The diagnostics and the system status are updated from the battery energy control module to hybrid/EV powertrain control module 2 through the serial data. Also the hybrid/EV powertrain control module 2 is the main controller for the diagnostic trouble code information.

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

• A significant rise in fuel consumption
  
• A fault in the hybrid/electric vehicle battery pack
• A failure in the hybrid/electric vehicle battery interface control module

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0B6B code by mentioning some major symptoms below:

Common Symptoms

• An increase in the fuel consumption
• engine light illuminated (or service engine soon warning light)

Have a look at some ways with which you can correct the P0B6B code:

• Mend or restore the electrical components that are noted to be damaged, corroded or loose as per the requirements. Then the system should be retested and set again. Also, If one fails to find any burnt, defective or shorted wiring or loose connectors, then the exhaust gas temperature/pressure (or heated oxygen) sensor connector should be disconnected and then the exhaust gas temperature sensor should be removed too.
• While cooling if the resistance level fails to fall with heat and or rise as it cools, the sensor should be replaced right away. Next, if everything turns out to be functioning in order, the key should be turned to the "ON" position and the presence of a voltage (and a ground signal) should be verified at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
• A possible fault in the PCM (or other related controller) should be suspected if the fuel shutoff switch and all system circuitry turns out to be working in order.

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 hybrid battery, hybrid battery pack, hybrid battery voltage sensor, battery cable, battery assembly, battery control module, powertrain control module, battery connection, exhaust leak, battery smart unit and a lot more. We are sure that now all your issues would be resolved.

Want to diagnose the error code P0B6B? Well, then you should follow these steps in order to diagnose this fault code:

An advanced OBD-II trouble code scanner should be applied to diagnose this trouble code P0B6B. The scanner should be used to check and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be test driven to see if the code persists. If the code vanishes it could likely be due to a malfunctioning diagnose or may display an intermittent issue.

Common mistakes when diagnosing the P0B6B Code

Fearing a misdiagnosis? Well, we advise you to avoid these mistakes in order to avoid a faulty diagnosis:

• A defective high voltage battery connection
• A damaged high voltage battery assembly
• Wiring problems
