<<See All OBD Codes

Error code P0B6D? See the check engine light illuminated? Don’t know what to do? Well, all you need is the Parts Avatar’ brief guide that’ll definitely help you solve the error code P0B75. Generally, this OBD-II code increased fuel consumption is known as a hybrid battery voltage sense "L" circuit high. The high voltage battery pack is built of a large number of mini-batteries linked together. The code P0B75 is stored by the high voltage control module, when the high voltage control module registers a defect with one or more battery packs that embody the high voltage battery assembly.

Generally, the composition of the hybrid/electric vehicle battery pack includes 288 cells. Sets of three cells are all soldered together in uniformity. Also, a total number of 96 cell groups can be found in the hybrid/EV battery pack assembly. Linked together, all these cell groups are connected through an electrical connection in-series. The individual cell group is often rated at 3.7 V for a nominal system voltage of 355 V direct current. All these battery sections can be observed to be further sectioned into three. The battery section one is composed of first 90 cells/30 cell groups. One can note this section located close to the cowl consisting of batteries changing from 67 to 96. The battery section one is located in front of the battery section two. This section consists of 72 cells/24 cell groups each containing batteries from 43 to 66. The section number three is the transverse battery section, which comprises of the remaining 126 cells/42 cell groups and includes batteries 1 to 42. All these three battery sections can be serviced well individually.

It can be seen that the battery energy control module from time to time controls the voltage of the 96 battery cell groups with the help of the four hybrid/EV battery interface control modules. The voltage sense circuits are associated to each individual cell group and these sense circuits end at a connector built on the top surface of the battery section. Also found on the top surface of the battery section, a serviceable auxiliary battery wiring harness fixes this connector to a hybrid/EV battery interface control module. The hybrid/EV battery interface control module plays the role of constantly codifying the voltage reading and sending it forward to the battery energy control module through the battery control harness. On battery sections one and two, there is one hybrid/EV battery interface control module built. Two hybrid/EV battery interface control modules are linked with battery section three. All these components including the hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module can be seen serviceable parts. The function of detecting a fault condition is performed by the battery energy control module. Using serial data, the diagnostics and system status are transmitted from the battery energy control module to hybrid/EV powertrain control module 2. The The hybrid/EV powertrain control module considered to be the main controller for diagnostic trouble code information.

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

• A possible error in the hybrid/electric vehicle battery pack
• A distorted hybrid/electric vehicle battery interface control module

1. Hybrid battery - A steady decrease in the MPG, the ICE kicking more than the usual, large fluctuations in the state of charge (SOC) are likely to accompany a malfunction the hybrid battery. So in order to avoid major complications we recommend you to get these minor changes done right away.
2. Hybrid battery pack - If the car battery looks swollen or bloated it is due to an error in the hybrid battery pack. Apart from this a bad hybrid battery pack is likely to cause the dimming of the headlights,a terrible gas mileage and an a fall in the performance of various components is like to follow a hybrid battery pack failure. Get yours right at your doorstep with Parts Avatar. Log in now!
3. Hybrid battery voltage sensor - Low battery voltage, engine swelling and an imbalance in the system voltage is likely to hit along with the damaged hybrid battery voltage sensor. Its highly advised to get it changed in order to save a lot of time and money utilized further on major repairs.
4. Battery cable - Crumbling battery cables are harmful for the system. They can trigger dangerous misfiring conditions, overheating in the cables and a foul smell holding a danger to not only the engine but also the components nearby. Get your error code P0B75 fixed right away with new battery cables. Log into Parts Avatar now!
5. Battery assembly - Problem in starting the vehicle, slow cranking, also that the battery assembly is in direct contact with the battery they are constantly exposed to the acidic fumes from the battery acid and as a result are prone to developing corrosion. A defect in them can lead to a costly repair if left unattended.
6. Battery control module - The entire process of maintaining the system voltage gets disturbed if the battery control module is damaged. It not only harms the engine but the entire electrical components present too. Now get your error code fixed with Parts Avatar. We have it all for you. Tune in now.
7. Powertrain control module - A faulty PCM makes the car fail to start at times or begin to stall when the vehicle is running. Increased emissions are likely to follow. We recommend you to change yours right now. Don’t know where to look for? Tune into Parts Avatar.
8. Exhaust system parts - Performance issues are a commonly followed due to an erroneous exhaust system parts. If the parts become damaged or corroded, they can sometimes cause an exhaust leak. A leak or crack can lead to the vehicle to experiencing a significant reduction in power, ability to accelerate, and fuel efficiency due to the loss of back pressure. Tune into Parts Avatar for premium quality products.
9. Battery smart unit - Observing a drop in your battery bars with little or almost no usage? When you park the vehicle with full bars and come back to it with only one bar left, there is definitely a primary issue with the battery smart unit that needs to be checked as soon as possible. Apart from this a lot of issues follow too. Restore or repair just in time.

Here are some steps which you should follow in order to diagnose this fault code P0B75:

Well, to start with, the first step performed by the mechanic should be using a scanner (or code reader) and a digital volt/ohmmeter as these will be helpful in successfully diagnosing this code-storing condition. Next, it is essential to your diagnose with a visual inspection of system wiring, connectors, and components. It is recommended to restore or mend any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. Also, repair or replace system circuits/connectors as required and retest the system to ensure that repairs were successful.
