Error Code P0B73: What It Means & What To Do?
OBD Code P0B73 - Hybrid Battery Voltage Sense "L" Circuit Range/Performance
Error code P0B73? Well, all you need is this Parts Avatar’ brief
guide that’ll definitely help you solve the error code. The OBD-II code
increased fuel consumptionin also at times determined as a hybrid battery
voltage sense "L" circuit range/performance. Several mini-batteries
linked together constitute the high voltage battery pack. Whenever the high
voltage control module registers a malfunction with one or more battery packs
that make up the high voltage battery assembly, the high voltage control module
displays the code P0B73.

Well, it can be noted
that the battery energy control module controls the voltage of the 96 battery
cell groups by employing the four hybrid/EV battery interface control
modules.also, linked to every cell group are the voltage sense circuits. All
these sense circuits conclude at a connector situated on the top surface area
of the battery section. An auxiliary battery wiring harness( serviced
individually) links this connector to a hybrid/EV battery interface control
module that can be found on the top surface of the battery section. The
hybrid/EV battery interface control module plays the role of decoding the
voltage reading and then transmitting it to the battery energy control module
through the battery control harness. A single hybrid/EV battery interface
control module is situated on the battery section one and two, while two of the
are located on the battery section three. The scheme of the components that can
be serviced well individually include the hybrid/EV battery interface control
module, battery energy control module wiring harness, auxiliary battery wiring
harness, and battery energy control module. The presence of the fault condition
in the system is notified by the battery energy control module. Both the
diagnostics and the system status are conveyed from the battery energy control
module to hybrid/EV powertrain control module 2 via serial data. All the
diagnostic trouble code information is mainly stored and controlled by the
hybrid/EV powertrain control module 2.
What causes this problem
with the Hybrid Battery Voltage Sense "L" Circuit Range/Performance?
- A malfunctioning hybrid/electric vehicle battery pack
- An error in the hybrid/electric vehicle battery interface control module
- Increase in the fuel consumption
Replace/Repair These Parts to Fix OBD Code P0B73
- Hybrid battery - Flashing dash lights and engine lights is the first thing a
driver may notice. If a deviation in the fuel economy is noticed it is likely
due to a failure in the hybrid battery. This may ultimately lead to a fault
being triggered in the entire system, requiring a major expensive and time
consuming repair. Well, get yours changed now from Parts Avatar.
- Hybrid battery pack - Replacing or repairing the hybrid battery pack may often
require your thousands of dollars as it leads to major problems such as
internal combustion running more, strange drop in the battery voltages as well
as weird noises. We recommend you to get yours changed from Parts Avatar right
before it gets too late.
- Hybrid battery
voltage sensor - The
battery is likely to sit at one purple bar if not zero whenever there is
malfunction. All sorts of odd check engine lights are likely to flash on
whenever there is a fault in the hybrid battery voltage sensor. This may at
times also lead to disturbance in the entire system leading to a super
expensive repair. Tune into Parts Avatar just in time to avoid these minor
problems building up a major error.
- Battery cable - The battery cables present serve the primary function of
connecting the vehicle’ entire electrical circuit. This is likely to be
followed by a complete short circuit in the battery in the system. Change or
repair now.
- Battery assembly - One of the most common thing observed is a visible
corrosion due to a defect in the battery assembly. Low fuel consumption,
decreasing efficiency and power are the most common problems suffered by the
driver. We advise you to change yours now before it gets too late.
- Battery control module - This part
plays an essential and comprehensive role in the electrical components present
in the system. Even a minor fault can at times lead to a major fault causing
the loss of time and lots of unnecessary dollars. In order to avoid further
complications, tune into Parts Avatar to get your battery control module
delivered right at your doorstep.
- Powertrain control
module -
This part is often defined a the brain of the system. A badly functioning
engine, constant halts while starting the engine (as it ensures the smooth
functioning of the camshaft and crankshaft) and a consequent failure in the
system is accompanied with a faulty powertrain control module.
- Exhaust system parts - As the exhaust system parts are likely to withstand
excessive heat and extreme temperatures, these are prone to damages. Also, a
problem in them leads to strange noises, cracks in the exhaust system pipes or
breaking in the exhaust manifolds too. We advise you to change or restore the
exhaust system parts as soon as possible.
- Battery smart unit - A distorted battery smart unit is likely to be the chief
host inviting a lot of issues like possible fluctuation in the fuel gauges
(that end up giving the wrong readings), bad gas mileage shortening the life
span of the other parts present in the system. So tune into Parts Avatar right
away to get your malfunctioning battery smart unit changed.
Symptoms of OBD Error Code P0B73
It is vital to know the
symptoms of an issue as only then you would be able to solve the problem. So
that’s why we have listed out some major symptoms of OBD Code P0B73 here:
Common Symptoms
- Increase in the fuel consumption will be observed

How To Correct P0B73 Hybrid Battery Voltage Sense "L" Circuit Range/Performance
Here are some ways with
the help of which you will be able to correct the OBD Code P0B73:
- Replace or repair the hybrid/electric vehicle battery pack
whenever there has been a fault detected
- Measures should be taken to fix a damaged hybrid/electric vehicle
battery interface control module
- If a malfunctioning electronic control unit is detected, make sure
to change or replace it immediately
- A powertrain control module that fails to function according to
the requirements should be changed as soon as possible
- Change or mend an unsound hybrid battery voltage sensor too

Easy Diagnosis Of Engine Error OBD Code P0B73
Want to diagnose the
error code P0B73? Well, then you should follow these steps in order to diagnose
this fault code:
A customary OBD-II
trouble code scanner should be employed to diagnose this trouble code P0B73.
The scanner should be utilized to verify and view the freeze frame data and
assess the code 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 persists. Also, it should be noted that if the code disappears it could
have likely been triggered due to a faulty diagnose or may represent an
intermittent issue.
Common mistakes when diagnosing the P0B73 Code
Only for you we have
listed here a few common mistakes that should be avoided when the code is
stored:
- A fault in the high voltage battery connection
- A distorted high voltage battery assembly
- Problems with the wiring
