P0B9E - OBD Trouble Code

<<See All OBD Codes

Terrorized? Can’t decide what to do? Don’t worry, we have written it all for you! Here’s all that you need to know about the error code P0B9E. This OBD-II code P0B9E hybrid battery voltage sense "T" circuit intermittent/erratic is also known as an increased fuel consumption. The high voltage battery pack is comprising of a large number of mini-batteries that are attached to each other. The high voltage control module sets the code P0B9E whenever it registers a malfunction in more than one or more battery packs that constitute the high voltage battery assembly.

Well, the of the hybrid/electric vehicle battery pack incorporates a total of 288 cells. All together there is are 96 cell groups present in the hybrid/EV battery pack assembly. These cell groups are electrically connected. It should be noted that all the individual cell group are ranked at 3.7 V for a nominal system voltage of 355 V direct current. Also, these battery cells are banded together and are further divided into three sections. The battery section one includes first 90 cells/30 cell groups. Situated near to the cowl, this section contains of batteries numbering from 67 to 96.

The battery section two is located on the back of the section one. Its composition includes cells from 72 to 24 cell groups and it also has batteries ranging from 43 to 66. Finally, the section number three is also known as the transverse battery section, that 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 this, the battery energy control module regulates the voltage of the 96 battery cell groups using the four hybrid/EV battery interface control modules. There are also voltage sense circuits that are connected to each of these individual cell groups. On the top surface area of the battery section, a connector is installed, where the voltage sense circuits terminate.

Situated 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 performed 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 connected 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 recorded 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 tagged to be the main controller for diagnostic trouble code information.

What causes this problem with the Hybrid Battery Voltage Sense "T" Circuit Intermittent/Erratic?

• Broken hybrid/electric vehicle battery pack
• Distorted hybrid/electric vehicle battery interface control module

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0B9E code to be stored:

A discharged battery or corroded battery cables should be suspected if there is a clicking noise heard while the engine is started and the engine fails to crank. This situation typically hints at a fault within the battery. While on the other hand, if the engine cranks when the car is started, but fails to turn over, a problem with the fuel or ignition should be blamed. A number of other reasons that stimulate this code include a failed starter motor relay, a blocked fuel filter, a damaged fuel pump or an ignition switch failure. When this error code P0B9E is stored you should check for a contaminated VCT solenoid. We advise you to refer to the vehicle specific repair manual to perform a components tests for the VCT unit.

Common Mistakes When Diagnosing the P0B9E Code

Here we have listed a few common mistakes that should be avoided while performing the error code:

• A defective high voltage battery connection
• Corroded high voltage battery assembly
• Damaged wiring
