What is P0E24?

The diagnostic trouble code P0E24 indicates an issue with the electric vehicle battery pack, specifically related to the battery voltage sensor. This code is primarily seen in hybrid and electric vehicles such as the 2014-2019 Chevrolet Volt and Nissan Leaf. When the vehicle’s onboard diagnostics detect that the battery voltage readings are outside the expected range, it triggers the P0E24 code. This can lead to several performance issues, including reduced power and efficiency, and in some cases, it may prevent the vehicle from starting altogether. Drivers may notice a sudden loss of acceleration or a significant drop in electric range. If left unaddressed, this issue can strain the battery pack further, potentially leading to costly repairs. Being informed about this code is vital for electric vehicle owners, as it can significantly impact the vehicle's overall functionality and long-term durability.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P0E24 is present:

  • The check engine light may stay illuminated, indicating a persistent issue with the battery pack.
  • Drivers might experience a loss of acceleration power, making it difficult to merge into traffic or climb hills.
  • Fuel efficiency, or electric range, could drop significantly, often by 20-30%, meaning you may need to charge the vehicle more frequently.
  • Unusual battery warning messages may appear on the dashboard, alerting you to potential issues.
  • In some cases, the vehicle may enter a 'limp' mode, restricting speed and functionality to protect the battery.

Possible Causes

Most common causes of P0E24 (ordered by frequency):

  1. The most common cause of the P0E24 code is a faulty battery voltage sensor, which can account for approximately 60% of cases. This sensor can wear out over time due to heat and vibration.
  2. A second cause could be damaged wiring or connectors within the battery pack, which may lead to incorrect voltage readings. Regular inspections help in early detection.
  3. Another potential cause is software or firmware issues in the vehicle’s battery management system. Ensuring that your vehicle is updated can help prevent these problems.
  4. Less commonly, a failing battery pack itself may trigger the P0E24 code, suggesting it may be time for a replacement.
  5. In rare scenarios, a malfunction in the vehicle’s onboard computer could misinterpret the battery’s voltage, leading to false readings and unnecessary repairs.
