P0B11 - OBD Trouble Code
OBD Code P0B11 - Hybrid Battery Pack Current Sensor "B" Circuit High
P0B11 error code arises due to the failure of a battery current sensor which is also generally known as the hybrid battery pack current sensor ’B’ circuit high. A current sensor, which belongs to the high voltage battery pack is placed on the negative battery cable. The charging and discharging of the battery pack is found by the sensor and informed to the battery control module. If the sensor circuit, finds out that the battery control module is malfunctioning, then the P0B11 error code will be set.

Inside the hybrid/EV battery pack, the hybrid/EV battery current sensor is placed. The positive high voltage cable will go through the hybrid/EV battery pack current sensor and finally reaches the positive contactor relay. The quantity of current that flows in and out of the hybrid/EV batteries is found by the hybrid /EV battery pack sensor. The battery energy module receives a signal between 0 and 5 V from the hybrid/EV battery pack sensor. The amount of current that goes in and out of the hybrid/EV battery pack is in the proper ratio with the hybrid/EV battery pack current sensor. If the voltage is greater than 2.5V, it shows that the hybrid/EV battery pack is charged and if it’s less than 2.5V, it is discharging. There are 2 measurement ranges provided by the hybrid/EV battery pack current sensor so as to maintain precision. These ranges might overlap with each other. -23 to +23A is for high resolution and -470 to +280A is for low resolution.
What causes this problem with the Hybrid Battery Pack Current Sensor "B" Circuit High?
- Defective battery energy control module.
- Battery energy control module harness might have an opening or short circuit.
- Battery energy control module circuit might have a weak electrical connection.

Easy Diagnosis Of Engine Error OBD Code P0B11
It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0B11 code to be stored:
- This is a general type of trouble code, where the mechanic will use a scanner to carefully look for any stored error code.
- He will then connect the scanner to the diagnostic port of the vehicle and recover all stored codes and freeze frame data as it can help him with further diagnosis.
- For this P0B11 error code, initially, the mechanic will carefully inspect the hybrid battery pack/ hybrid battery pack current sensor.
- Any possible damages have to be fixed immediately.
- As a next step, the mechanic will visually examine the components like battery cables, battery control module and battery current sensor.
- If any of these components are damaged, they will be replaced immediately by the mechanic.
- Finally, the mechanic will check for any possible faults in the engine control module and replace them quickly if there are damaged.
- After every of the diagnostic procedure is carefully done, the mechanic will reset the error code and then test drive the vehicle again.
- This will help him to know if the error code in the vehicle still occurs and also, helps him to locate the area as to where the fault occurred.
Common Mistakes When Diagnosing the P0B11 Code
- The high voltage battery assembly might be defective.
- The battery current sensor might be damaged.
- Defective battery control module.
