P0B76 - OBD Trouble Code

<<See All OBD Codes

Check engine light”? Alarmed? Well, we have penned down all you need to know about the error code P0B76. This generic OBD-II code increased fuel consumption in basic terms is also known as a hybrid battery voltage sense "L" circuit intermittent/erratic. A set of mini-batteries packed together constitute the high voltage battery pack. At times when the high voltage control module identifies an error with more than one battery packs that are found in the high voltage battery assembly, the high voltage control module stores the code P0B76.

Well, for your information we have written down here in detail about the error code P0B76. It can be noted that the HV battery installed makes use of the nickel metal-hydride batteries. These do not need any external charging at all. While driving, the power management control ECU regulates the SOC (state of charge) of the HV battery at a stable level. One can observe that the HV battery is contains 28 modules, each consisting of eight 1.2 V cells in series. At 14 locations, the battery block voltage is controlled by the battery smart unit. Each and every battery block has 2 modules in a set. The voltage of the battery is regulated by the battery smart unit also detects a damage that might have occured due to a voltage variation between the battery blocks exceeding the standards. The power management control ECU (HV CPU) illuminates the malfunction indicator lamp (MIL) and stores the diagnostic trouble code (DTC), whenever an error detection condition is there.

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

• A malfunctioning battery smart unit
• An erroneous HV battery assembly

1. Hybrid battery - Fluctuating fuel gauge, the gauge fluctuating and giving a wrong reading, a negative impact on the MPG as well as other electrical wirings and components is likely to follow a fault in the hybrid battery. Change yours right away with Parts Avatar.
2. Hybrid battery pack - Facing the error code P0B76? An inferior quality hybrid battery pack can always be hazardous for the system causing a sluggish engine start (if your car starts taking longer than normal to start). Tune into Parts Avatar for supreme quality hybrid battery packs at economical prices.
3. Hybrid battery voltage sensor - If the hybrid battery voltage sensor has any issue it tends to send an incorrect signal to the computer, that causes to interfere with proper charging and cause low voltage. Not only this a wide range of errors are followed along with it. Tune into Parts Avatar for good quality hybrid voltage sensors.
4. Battery cable - The battery cables not only affect the battery but indirectly affects all the components present in the system as it plays the role of connecting all to the battery. So it is essential to change the battery cables that are brittle and corroded in order to avoid repairs that can further be expensive caused due to bad battery cables.
5. Battery assembly - The damaged battery assemblies lead to a wide range of problems starting from difficulties faced while starting the vehicle, loss of electrical power, corrosion or short circuits in the battery as well as the components connected through it. Tune into Parts Avatar for the best quality battery assembly now!
6. Battery control module - Battery drained overnight? Don’t know the reason? Well, a damaged battery control module is the chief host inviting lots of issues with battery as well as the engine. Get your error code P0B76 fixed now with a new battery control module. Parts Avatar is just the right place for all your solutions.
7. Powertrain control module - Because of a PCM failure, downward emissions are likely to follow besides other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty PCM changed now by simply logging into Parts Avatar.
8. Exhaust system parts - The malfunctioning exhaust system parts are likely to cause excessive noise. If the exhaust pipes or manifold break or crack completely they can cause an exhaust leak. Now get your error code P0B76 fixed right now with new exhaust system parts. Log into Parts Avatar now.
9. Battery smart unit - The functioning of certain accessories, temperatures and driving may drain as a consequence of a malfunctioning battery smart unit. Well, you can get that fixed with a new battery smart unit. Tune into Parts Avatar now!

Want to diagnose the error code P0B76? Well, then you should follow these steps in order to diagnose this fault code:

To begin an accurate diagnosis, make use of a standardized 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 P0B76

Fearing a misdiagnosis? Well, we have listed here for you a few common mistakes that should be avoided while performing the procedure:

• A fault in the high voltage battery connection
• A failing high voltage battery assembly
• Wiring issues
