P0A8C OBD-II: 14 Volt Power Module System Voltage Unstable

P0A8C Severity

Moderate

Will P0A8C 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.

Schedule Diagnosis

What causes OBD-II fault code P0A8C?

The 14V Power Module, also referred to as the Accessory DC Power Module, monitors the current to the low voltage systems. If the voltage fluctuates excessively, the 14V Power Module will set code P0A8C and disable the low voltage system.
