<<See All OBD Codes

Are you clueless as what ’14-volt power module system voltage high’ mean? Are you looking for information about P0A8E error code, symptoms, the common mistakes that are made and the diagnostic procedures? Keep reading further. The error code P0A8E will get stored in the vehicle by the engine control module (ECM) if the vehicle does not meet the factory specifications and malfunctions.

The malfunctioning of the low voltage system is generally termed as the 14-volt power module system voltage high. The accessory DC power module which is otherwise known as the 14-volt power module observes the flow of current to the low voltage system. In this scenario, when the voltage gets too less, the error code P0A8E will be stored in the vehicle by the 14-volt power module. The 14-volt power module will finally disconnect the voltage system which is high.

What causes this problem with the 14 Volt Power Module System Voltage High?

• 14-volt power module malfunctions.
• An opening or shorted circuit might be present in the 14-volt power module harness.
• Poor electrical connection of the 14-volt power module circuit.
• The software of the 14-volt power module needs to be updated.

1. 14 Volt Power Module - P0A8E error code can get stored in the vehicle if the 14-volt power module is found to be damaged. Replace the faulty 14-volt power module immediately.
2. 14 Volt Power Module Harness - Are you looking for a replacement for your 14-volt power module harness? Get them from Parts Avatar at best prices online.
3. 14 Volt Power Module Software - Carefully check if the software of the 14 -volt power module is updated. If they are not updated, update them quickly.
4. Engine Control Module (ECM) - A faulty engine control module can give rise to the P0A8E error code in the vehicle which will result in malfunctioning. Replace the faulty ECM instantly.
5. Car Battery - As a very rare case, you may find the car battery to be damaged or dented which has to be changed immediately so as to avoid the P0A8E error code.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• P0A8E is a common type of trouble code which can be easily diagnosed.
• The mechanic will start the diagnostic process by using a scan tool to check for the error codes in the vehicle. At times, he will connect the scanner to the diagnostic port of the vehicle and recover the codes and freeze frame data.
• For an advanced diagnostic process, an advanced tool called – Autohex will be used by the mechanic to identify the exact location of the error.
• A visual inspection of the 14-volt power module harness will be carried out to see if the joints are damaged or detached. The damaged harness will be addressed by the mechanic.
• After checking the harness, the 14-volt power module will be inspected for any damages or defectives.
• The software of the 14-volt power module has to be updated. At times, the error code can get stored in your vehicle if the software is not updated when needed.
• At times the faulty or defective engine control module can give rise to the error code. If the ECM is found to be faulty, then the mechanic will replace them quickly.
• After performing each of this diagnosis, the mechanic will check to see if the error code keeps appearing.
• If the mechanic finds out that the error code still appears, he will check for the battery as to if it is damaged or bulged. A damaged battery will give rise to the cranking sound in the engine. If this arises, then the battery will be changed.

Common Mistakes When Diagnosing the P0A8E Code

• The engine control module might be damaged (ECM).
• Problem with the batteries.
• Not carrying out the software updates.
