The P1B28 fault code refers to a circuit issue in the 27th battery cell group of a hybridelectric vehicle.

The battery pack contains 288 cells grouped in parallel and connected in-series, with a nominal voltage of 355 V DC. The battery energy control module monitors the voltage of the cell groups through hybridEV battery interface control modules and communicates with the powertrain control module 2 for diagnostic trouble code information.

The battery sections and their components are individually serviceable.

What are the possible causes of the P1B28 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B28 fault code. This code is usually caused by a faulty hybrid/electric vehicle battery pack or a faulty hybrid/electric vehicle battery interface control module. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P1B28 fault code?

If you’re experiencing the P1B28 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Hybrid/Electric Vehicle Battery Pack or a faulty Hybrid/Electric Vehicle Battery Interface Control Module.
