P0B7C OBD Error Code: Problem & Solutions

<<See All OBD Codes

This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

The PCM continuously monitors the signals out of the battery current sensor and stores a specific error if the voltage signals if out of its specifications. Thus, if the Hybrid Battery Voltage Sense “N” circuit is unstable, the PCM will store OBD code P0B7C in the system.

What causes this problem with the Hybrid Battery Voltage Sense "N" Circuit?

• Faulty Hybrid Battery “N” Voltage
• Malfunctioning wiring and connectors to the battery
• There can be inoperative car battery
• PCM/ECM might be flawed

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

• Use of an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
• The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
• The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
• The tests related to the hybrid battery and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further helping the cause.
• The P0B7C error is triggered if there is a physical problem with the battery which could cause the engine performance to go off.

Common Mistakes When Diagnosing the P0B7C Code

Though the hybrid battery itself is generally the cause of P0B7C, using the proper tools and following the complete diagnostic procedure without skipping any steps is required as to avoid unneeded repairs. Monitoring the sensor data from the scan tool live data stream is the only way to check for proper operation, and the sensor should not be replaced until it is tested. P0B7C has easily managed symptoms but like any other code, it should be repaired at the earliest convenience. In rare cases where the vehicle runs poorly and the fuel economy goes down, caution is advised when driving to avoid any issues.
