<<See All OBD Codes

Do you know how the P0B16 error code gets stored in the vehicle? What are its causes and symptoms? You have landed in the right place for the information. The careful monitoring of the hybrid battery pack voltage sense ‘B’ circuit is done by the engine control module (ECM). The error code will be set in the vehicle by the ECM, if the hybrid battery pack voltage sense ‘B’ circuit does not fulfill the factory specifications.

Learn More About OBD Error Code P0B16

The hybrid battery pack voltage sense ‘B’ circuit low is a common type of diagnostic trouble code. Over 300 individual cells are present in a hybrid battery pack which is finally joined together. A voltage monitor is fixed to each and every group so that the hybrid powertrain control module or the battery control module will get the information of each cell group’s available voltage. If the voltage is less in each cell group, then the error code P0B16 is set.


What causes this problem with the Hybrid Battery Pack Voltage Sense "B" Circuit Low?


  • Malfunctioning of the hybrid battery pack.
  • The hybrid battery pack harness might have a short circuit or you might find an opening.
  • The electrical connection might be poor in the circuit of the hybrid battery pack.

Easy Diagnosis Of Engine Error OBD Code P0B16

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


  • This is a general type of error code, where the diagnosis process and the repair work is not difficult to execute.
  • Whenever this error arises, the mechanic will use a scanner to check the trouble codes in the vehicle. But a trained professional will use an advanced scanner like Autohex- to check for advanced diagnostic process.
  • The mechanic will carefully look into the hybrid battery pack and hybrid battery pack current sensor if they are broken, damaged or corroded. If they are defective it will be replaced quickly.
  • After this, the mechanic will look for possible damages in some of the electrical components like battery cables, battery control module, battery current sensor and so on. Any damage to these components can also result in the storing of the error code.
  • As a very rare case, you will find the engine control module to be faulty which has to be replaced quickly.
  • If there are any other error codes, they must be rectified first, before further proceeding with the P0B16 error code.
  • After the diagnosis, it is good to always reset the code and the vehicle must be test driven to know if the issue is resolved. Test driving the vehicle will help the mechanic to know as to where the error occurred.


Common Mistakes When Diagnosing The P0B16 Code


  • Malfunctioning of the battery contactor assembly.
  • The battery energy control module might face some issues.
