P0A8E OBD-II: 14 Volt Power Module System Voltage High
P0A8E Severity
Will P0A8E go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0A8E?
The 14V Power Module, also referred to as the Accessory DC Power Module, monitors the current to the low voltage systems. If the voltage gets too low, the 14V Power Module will set code P0A8E and disable the high voltage system.
