Error Code P0B49: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0B49 can be explained as Hybrid Battery Voltage Sense "C" Circuit Intermittent/Erratic. It is important to know that the wrong battery voltage can severely affect the engine performance as well as the fuel economy. Also affected by the sluggish acceleration and the braking risk, the OBD code P0B49 error code gets stored in the PCM indicating problematic hybrid battery.

Are you tensed because the P0B49 fault code is flashing? We have got everything which you need and at equitable prices. You must visit us and we promise that you will never regret your decision. The PCM sets the OBD code when the hybrid battery pack voltage sense "C" circuit signal is out of factory specifications. The high voltage battery is composed of many individual battery cells and the battery energy control module monitors all the cells in the high voltage battery pack to make sure they are all contributing equally to the high voltage system. If one cell is determined to be unequally contributing, code P0B49 will be set.

What causes this problem with the Hybrid Battery Voltage Sense 'C' Circuit Intermittent/Erratic?

• Problematic hybrid battery pack
• Issue of unbolted hybrid battery pack harness
• Damaged or broken battery connectors and wirings
• Bad electrical connection in the hybrid battery pack circuit

Interested in knowing the symptoms to OBD code P0B49? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

• Illuminated service engine soon light
• Poor acceleration and gear shifts
• Delayed throttle response
• Increased toxic emissions from exhaust

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return,then there can be an erratic condition.
• But, if the error code returns,then the mechanic has to check the transmission fluid.
• If the transmission fluid is dirty or if it is below the expected level, it has to be refilled or the dirty fluid has to be replaced.
• Also, the mechanic can check for any sign of leaks, and quickly fix the issue.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• If the issues are not yet sorted out, then the mechanic will use a digital voltmeter/ ohmmeter and connect it to the vehicle.
• Once the circuit is inspected, he will thoroughly check all the harness and repair them accordingly.
• In most cases, this error code can arise mostly because of any shorted wires or dirty or contaminated transmission fluid.
• Whenever the mechanic or a trained professional, repairs any of the component like wires or connectors, he will reset the code and test drive the vehicle again to see if the error code appears again.
• This can actually help the mechanic to know if the problem is fixed.

Common Mistakes When Diagnosing The P0B49 Code

• Malfunctioning battery contactor assembly
• Battery circuit damages
• Battery wiring and connector problems
• Failure in the battery energy control module
