Guide To P0B79 OBD Error Code Solutions

<<See All OBD Codes

Terrorized? Still see the error code P0B79 popping? Well, we are here to help you out. This OBD-II code increased fuel consumption when put in simple terms is known as a hybrid battery voltage sense "M" circuit low. Several mini-batteries linked together make up the high voltage battery pack. The code P0B79 is displayed by the high voltage control module whenever the high voltage control module notifies an error in the battery packs that are there in the high voltage battery assembly.

It should be noted that the hybrid/electric vehicle battery pack incorporates in itself a total of 288 cells. There is an arrangement of three cells each that are all fused together in regularity. Apart from this, in the hybrid/EV battery pack assembly there are a total of 96 cell groups. All these cell groups are attached through an electrical connection that is in-series. The individual cell group can be seen to be rated at 3.7 V for a nominal system voltage of 355 V direct current. In three equal sections, the battery cells are divided. The battery section one can be seen being composed of first 90 cells/30 cell groups. This section can be located near to the cowl. It consists of batteries within 67 to 96. The battery section two can be found at the back of the section one. Containing 72 cells/24 cell groups the batteries present span from 43 to 66. The section number three is known as the transverse battery section. The remaining 126 cells/42 cell groups and batteries from 1 to 42 make up the section three. These three battery sections are valid for individual service.

In addition to that, the battery energy control module from time to time controls and regulates the voltage of the 96 battery cell groups utilizing the four hybrid/EV battery interface control modules. These voltage sense circuits are all teamed to each individual cell group. All these sense circuits end at a connector that can be observed on the top surface area of the battery section. A serviceable auxiliary battery wiring harness plays the role of connecting this connector to a hybrid/EV battery interface control module (also located on the top surface of the battery section). The hybrid/EV battery interface control module performs the essential function of encoding the voltage reading and further transferring it to the battery energy control module by the battery control harness. There is one hybrid/EV battery interface control module positioned over the battery sections one and two, while rest of the two hybrid/EV battery interface control modules are connected with battery section three. All the components namely the hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module can be individually serviced. 

Whensoever there is a malfunction, it is detected by the battery energy control module. All the diagnostics and system status present are regularly updated from the battery energy control module to hybrid/EV powertrain control module 2 using the serial data. Also, all the diagnostic trouble code information is stored and saved in the hybrid/EV powertrain control module 2.

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

• A damaged hybrid/electric vehicle battery pack
• A failure in the hybrid/electric vehicle battery interface control module

1. Hybrid battery - Whenever the hybrid battery fails, one is likely to observe a decrease in the MPG. Also, an error in the hybrid battery is likely to spark symptoms that may lead to an unusual MPG. In addition to these the driver is likely to observe a high mileage. Don’t know where to look? Well, Parts Avatar has it all. Tune into Parts Avatar for premium quality products now.
2. Hybrid battery pack - Facing the error code P0B79? Only for your information, we would like to inform you that an error in the hybrid battery also affects the headlights (dimmer headlights), slow functioning of the engine and unusual noises. Well, get that fixed with a new hybrid battery pack available online at Parts Avatar at the best prices.
3. Hybrid battery voltage sensor - A hybrid battery voltage sensor when after being diagnosed as faulty is not fixed it leads to hampering the functionality of lot of electrical components located nearby. So in order to save your money and time tune into Parts Avatar for supreme quality products offered at the best prices.
4. Battery cable - Weary and damaged battery cables can often be problematic. So to add some spark to your ride and avoid further complications with the battery, engine and other electronic components you definitely need the perfect quality battery cables offered at Parts Avatar. Isn’t that just the perfect deal? 
5. Battery assembly - Corroded or loose battery assemblies lead to unnecessary halts in your journey (a slow engine crank), inability to conduct power and a decreased electric power. Replace or repair them as soon as possible to avoid further expensive repairs.
6. Battery control module - Facing the error code P0B79? An inferior quality battery control module can always be hazardous for the system also it is one of the primal causes stimulating the error code P0B79. Tune into Parts Avatar for good quality battery control modules at economical prices.
7. Powertrain control module - A failure in the overall ability of the engine is likely to be followed due to a malfunctioning powertrain control module as it is the most essential unit installed. Tune into Parts Avatar for top notch PCMs.
8. Exhaust system parts - One of the problems with the exhaust system parts include a burning smell from the engine bay. While manifolds are installed as to be heavy duty parts, they withstand over nine hundred degrees Fahrenheit if there are any issues with the heat shield or exhaust leaks. Even a minor fault can lead to a lot of your money wasted on major repairs. Tune into Parts Avatar for exhaust system parts.
9. Battery smart unit - A defective battery smart unit can end up being the chief host inviting the error code P0B79. So replacing one can be one of the wisest decisions to avoid a problematic system.

Interested in knowing the symptoms to obd code P0B79? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Do you want to diagnose the error code P0B79? Well, then you should follow these steps in order to diagnose this fault code:

To begin an accurate diagnosis, make use of an improved OBD-II trouble code scanner. The scanner should be utilized to check and confirm the code and view the freeze frame data by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be cleared and the vehicle should be test driven to see if the code reappears. If the code disappears it could likely be due to a faulty diagnose or may signify an intermittent issue.

Common mistakes when diagnosing the P0B79

Listed here are a few common mistake that should be avoided while performing the procedure:

• A defect in the high voltage battery connection
• A distorted high voltage battery assembly
• Problems due to the wiring
