P0AF8 Meaning

The P0AF8: Hybrid Battery System Voltage fault code indicates that there is a voltage issue within the hybrid battery system. This could involve readings that are too high, too low, or fluctuating outside of normal operating parameters. A faulty voltage sensor, wiring issues, or a malfunction in the control module could be the cause. If left unchecked, this may affect the hybrid system’s ability to store and deliver electrical power efficiently.
