What is P0C87?

The DTC P0C87 code indicates a failure in the hybrid powertrain system, particularly associated with the battery cooling system. This code commonly appears in vehicles like the 2016-2020 Chevrolet Volt, where the hybrid battery management system detects irregularities in the voltage or temperature readings from the battery pack. When this occurs, the vehicle may enter 'limp mode,' reducing power to prevent further damage. It could be triggered by factors such as a malfunctioning battery cooling fan, faulty temperature sensors, or issues with the battery control module. Ignoring this issue can lead to reduced fuel efficiency, increased emissions, and ultimately, a complete hybrid system failure, necessitating expensive repairs. Therefore, it's crucial for owners experiencing this code to address it promptly to maintain vehicle performance and avoid costly repairs down the line.

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

Symptoms

Common symptoms when P0C87 is present:

  • The check engine light illuminates, signaling a problem that requires immediate attention.
  • The vehicle experiences reduced power output, making acceleration sluggish and less responsive.
  • A noticeable decrease in fuel economy, potentially up to 20%, as the hybrid system struggles to function efficiently.
  • The hybrid system may intermittently shut down, leading to a complete loss of power while driving.
  • In some cases, unusual noises may emanate from the battery compartment, indicating potential mechanical failures.

Possible Causes

Most common causes of P0C87 (ordered by frequency):

  1. The most common cause of P0C87 (60% likelihood) is a malfunctioning battery cooling fan, preventing the battery from maintaining an optimal operating temperature.
  2. Another frequent issue (25% likelihood) stems from faulty temperature sensors that fail to provide accurate readings, leading to incorrect system responses.
  3. Electrical problems, such as corroded connectors or damaged wiring within the hybrid system, can trigger this code (10% likelihood). Regular inspections can help prevent these issues.
  4. A less common but serious cause (3% likelihood) is a failure in the battery control module, which can compromise the entire battery management system.
  5. Rarely, P0C87 may be triggered by software issues within the vehicle's ECU, requiring a software update or reprogramming to resolve.
