P0B6E - OBD Trouble Code

OBD Code P0B6E - Hybrid Battery Voltage Sense "K" Circuit Range/Performance

<<See All OBD Codes

Worried? Don’t know what to do? See the error code P0B6E? Well, here’s how you can crack the error code P0B6E. This OBD-II code Increased fuel consumption in common terms is determined as a hybrid battery voltage sense "K" circuit range/performance. It can be observed that there are many mini-batteries connected together that constitute the high voltage battery pack. Whenever the high voltage control module identifies a defect with more than one battery packs that make up the high voltage battery assembly, the code P0B6E will be stored by the high voltage control module.

288 cells make up the hybrid/electric vehicle battery pack with groups of three cells connected together in correspondence. All together there is a total of 96 cell groups in the hybrid/EV battery pack assembly (these cell groups are electrically connected in order). It should be noted that each and every individual cell group is rated at 3.7 V for a nominal system voltage of 355 V direct current. Also, these battery cells are tied together and divided into three sections. The battery section one includes first 90 cells/30 cell groups. Located close to the cowl, this section consists of batteries from 67 to 96. Next, the battery section two is located on the backside of the section one. Composed of 72 cells/24 cell groups and it also has batteries ranging from 43 to 66. The section number three is known as the transverse battery section, it constitutes of the rest of the 126 cells/42 cell groups and contains batteries from 1 to 42. All these three battery sections found can be easily serviced individually.


In addition to that the battery energy control module controls the voltage of the 96 battery cell groups using the four hybrid/EV battery interface control modules. One can observe voltage sense circuits that are connected to each of these individual cell groups. On the top surface of the battery section, a connector is built where the voltage sense circuits terminate. Also located on the top surface of the battery section is a serviceable auxiliary battery wiring harness that connects this connector to a hybrid/EV battery interface control module. The decoding of the voltage reading is done by the hybrid/EV battery interface control module which is further transmitted to the battery energy control module via the battery control harness. The battery sections one and two has only one hybrid/EV battery interface control module while there are two hybrid/EV battery interface control modules linked with battery section three. The components that are serviceable include the hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module. The presence of a fault condition is detected by the battery energy control module. The diagnostics and system status are constantly transmitted from the battery energy control module to hybrid/EV powertrain control module 2 by the serial data. Also, the hybrid/EV powertrain control module 2 is considered to be the main controller for diagnostic trouble code information.


What causes this problem with the Hybrid Battery Voltage Sense "K" Circuit Range/Performance?


  • A damaged hybrid/electric vehicle battery pack
  • A defective hybrid/electric vehicle battery interface control module

Symptoms of the OBD Error Code P0B6E

For us our customers are everything, and that’s why we will help you to diagnose P0B6E code by mentioning some important symptoms below:


Common Symptoms


  • Rise in fuel consumption
  • Engine light blinking (or service engine soon warning light)

How to Correct P0B6E Hybrid Battery Voltage Sense "K" Circuit Range/Performance Issue

After you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle’s.


  • Firstly, begin by visually diagnosing the components. All the electrical parts that are found as defective, burnt or open as per the requirements. Then the system should be test driven and then reset. Also, if no open, defective or shorted wiring or loose connectors, then the exhaust gas temperature/pressure (or heated oxygen) sensor connector should be detached and then the exhaust gas temperature sensor should be detached too.
  • As the is cooling done, one should note that if the resistance level does not decrease with heat and increase as it cools, the sensor should be changed. Next, if everything turns out to be according to the requirements, the key should be turned to the "ON" position and the presence of a voltage (and a ground signal) should be tested at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
  • A distorted PCM (or other related controller) should be suspected if the fuel shutoff switch and all system circuitry turns out to be working well.

Apart from this, you might need to replace other damaged parts too like 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 more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

Easy Diagnosis Of Engine Error OBD Code P0B6E

We have listed here a few simple measures that should be taken in order to solve the error code P0B6E:


One can always observe banging or grinding noises due to broken or damaged engine mountings. Generally, mounting can be broadly divided into two major types: one in which it is centrally placed close to the bottom of the block and the other one is the one higher up the block which mount on to the inner wings or the frame members. Also, it should be noted that merely just replacing the sensor won't solve the underlying error, if the P0B6E OBD-II registers a sensor fault. The systems monitoring the sensor or the wirings to the sensor itself might be at fault triggering the error code P0B6E.


Common mistakes when diagnosing the P0B6E Code


Listed here are a few common mistakes that should be avoided while diagnosing the error code P0B6E:


  • A failure in the high voltage battery connection
  • A malfunction in the high voltage battery assembly
  • Complications with the wiring
