Error Code P0B73: What It Means & What To Do?

OBD Code P0B73 - Hybrid Battery Voltage Sense "L" Circuit Range/Performance

<<See All OBD Codes

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.

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
