P0B50 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0B50 can be defined as Hybrid Battery Voltage Sense "E" Circuit Range/Performance. Is your car engine not starting again? Do you notice increased fuel consumption over recent period of time? And is your car engine performance degrading? If all this is true, then there might be a problem with hybrid battery voltage indicating the OBD Code P0B50 error. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P0B50 error code. The powertrain control module monitors the hybrid battery voltage sense 'E' circuit and PCM sets the error when the circuit signal is out of specifications. The high voltage battery is composed of many individual battery cells which are monitored to make sure they are all contributing equally to the high voltage system. When any specific cell is not able to produce enough voltage, OBD code P0B50 gets stored and flashed in the system.

What causes this problem with the Hybrid Battery Voltage Sense "E" Circuit Range/Performance?

• Some issues related to the hybrid/electric vehicle battery pack
• There can be distorted hybrid/electric vehicle battery interface control module
• Poor electrical connections to hybrid battery pack

1. Car Battery - Did your mechanic just found out that there is some fault in the Car Battery? Buy top notch Car Battery from us at economical prices.
2. Hybrid Battery - A broken Hybrid Battery can cause a lot of issues. It would be nice if you get it replaced on time.
3. Car Exhaust System Parts - Everything is fine with the engine control module and still OBD code P0B50 flashing? Then there is definitely some fault with the Car Exhaust System Parts. Get it checked and replace if needed.
4. Powertrain Control Module - Powertrain Control Module is an important car part which should never be neglected. May be there is some fault in it due to which P0B50 code may start flashing.
5. Exhaust Manifold - A faulty Exhaust Manifold can be troublesome. You can always rely on us as we have best auto parts for our customers.
6. Engine Control Module - If everything is alright with Exhaust Manifold, then there is surely some defect in Engine Control Module. Get it replaced before the situation gets worse.

Here are some steps which you should follow in order to diagnose this fault code:

• 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.
• Then the mechanic has to check the hybrid battery and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged hybrid battery and its components for error. It the mechanic finds the fault in the connectors in relation to the battery, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• Some smoke or steam might start getting emitted from underneath the car hood. The ignition timing could be set wrongly and there would be a need to adjust it properly. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced.
• If you find out that there is a pool of fluid underneath the car, this could be a sign of failure in the cylinder head gasket. That will be confirmed in the form of billowing smoke being blown from the exhaust system.
• Parts or components should not be replaced with reference to only a P0B50 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P0B50 Code

• Non performance of the high voltage battery assembly
• Failure in the car wiring
• The high voltage battery connection might not function properly
