Chevrolet P0AFA Code is a code that appears when the hybrid battery system voltage is too low. The engine is running or is in autostop mode, and the 12V system voltage is between 9.5-18V when this code is detected. This code can be caused by various factors, such as the ACCM detecting that the hybrid battery voltage is less than 191 volts for 3 seconds, and can be related to various service bulletins. In order to understand the causes and solutions for this code, it is important to review the related service bulletins to determine the cause and the necessary steps for repairs.

This code can be the result of a variety of problems, so it is important to review the related service bulletins to determine the cause and the necessary steps for repairs.
The Battery Is Not Charging
Another common cause of the P0AFA code is a battery that is not charging correctly. To resolve this issue, it is important to check the battery, battery cables, and connections to make sure they are clean and secure. If the battery is found to be defective, it should be replaced with a new one.
Hybrid Battery Control Module
In some cases, the P0AFA code may be caused by a defective hybrid battery control module. If this is the case, the module should be replaced with a new one. It is important to review the service bulletins to ensure that the correct replacement module is chosen.
Conclusion
The Chevrolet P0AFA code can be caused by various factors, such as the ACCM detecting that the hybrid battery voltage is less than 191 volts for 3 seconds. To understand the cause and solution of this code, it is important to review the related service bulletins to determine the cause and necessary steps for repairs. In some cases, the Chevrolet P0AFA Code may be caused by a defective hybrid battery control module, and a new battery or module may need to be installed for a successful repair.
