P1B9E fault code can be caused by a faulty battery pack or battery interface control module in hybridelectric vehicles.

  • The automobile fault code P1B9E can be caused by a faulty Hybrid/Electric Vehicle Battery Pack.
  • It can also be caused by a faulty Hybrid/Electric Vehicle Battery Interface Control Module.
  • These are the only two causes of this particular fault code.

To fix the p1b9e automobile fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1b9e, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1B9E has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P1B9E will depend on the hourly rate charged by the repair shop.

It is important to consider these factors when budgeting for the repair of this fault code.

The P1B9E code is related to the HybridElectric Vehicle battery pack.

The battery pack contains 288 cells grouped in parallel and connected in-series. The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybridEV battery interface control modules.

The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2 through serial data. The P1B9E code indicates a high voltage issue in the HybridElectric Vehicle Battery 62 Circuit.
