What is B0B60?

The diagnostic trouble code (DTC) B0B60 refers to an issue with the hybrid battery voltage sensor circuit, predominantly seen in Toyota and Lexus hybrid vehicles, such as the 2010-2015 Toyota Prius and the 2012-2017 Lexus CT200h. This code indicates that the high-voltage battery management system has detected a fault in the voltage sensor to monitor the battery's performance. When the battery voltage sensor circuit encounters problems, it can lead to improper voltage readings, which can adversely affect vehicle performance, fuel efficiency, and overall safety. If left unaddressed, this issue could lead to a complete hybrid system failure, causing the vehicle to enter limp mode, where the engine power is significantly reduced. Drivers may experience symptoms like reduced power during acceleration, the check hybrid system light illuminating, or the vehicle failing to start altogether. Prompt attention to this code is essential for maintaining the integrity of the hybrid system and ensuring safe operation of your vehicle.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0B60 is present:

  • The check hybrid system light stays on, signaling an issue with the hybrid system.
  • Reduced engine power is noticeable, especially during acceleration, making driving difficult.
  • Fuel economy may decrease significantly, often by 20-30% as the vehicle struggles to maintain efficiency.
  • The vehicle may experience a rough idle or stalling when attempting to switch between electric and gasoline power.
  • In some cases, the vehicle fails to start, indicating a severe issue with the hybrid battery management system.

Possible Causes

Most common causes of B0B60 (ordered by frequency):

  1. The most common cause of the B0B60 code is a malfunctioning voltage sensor, accounting for about 70% of cases. This can occur due to normal wear and tear or exposure to extreme temperatures.
  2. A wiring issue, such as damaged or corroded connectors in the battery management system, can also trigger this code. This is a technical issue that requires a thorough inspection.
  3. A faulty battery management control module may contribute to the B0B60 code, but this is less common. Regular maintenance can help prevent this.
  4. Less common but serious causes include internal battery failure, which can lead to complete hybrid system failure.
  5. Rarely, software issues in the vehicle's control system can cause false readings, thus triggering the B0B60 code without any actual hardware problem.
