What is OBD-II Code P0A8A – 14 Volt Power Module Current Sensor A Circuit Intermittent
If you own a car, chances are high that you’ve seen the check engine light come on at some point. With the advancement in technology, some cars have built-in systems that allow you to diagnose issues with your car without visiting a mechanic. One of such systems is the On-Board Diagnostic (OBD) system, which continues to evolve with each passing day. This system helps to diagnose issues with your car and provides you with a code that indicates what’s wrong. One of such codes is OBD-II Code P0A8A – 14 Volt Power Module Current Sensor A Circuit Intermittent. In this article, we will be exploring what the code P0A8A means, the causes of the issue, and how to carry out a repair on your car.
What is OBD-II Code P0A8A – 14 Volt Power Module Current Sensor A Circuit Intermittent?
OBD-II Code P0A8A is a DTC (Diagnostic Trouble Code) that occurs in Plug-In Hybrid Electric Vehicles (PHEV) or Hybrid Electric Vehicles (HEV). It refers to an issue with the 14-volt power module current sensor A circuit, which is responsible for monitoring the current flowing through the 14-volt power module in your car. When this circuit experiences intermittent issues, it results in Code P0A8A.
Causes of OBD-II Code P0A8A – 14 Volt Power Module Current Sensor A Circuit Intermittent
Before we proceed, it’s essential to state that Code P0A8A is peculiar to hybrid vehicles. That said, several factors can cause this issue. Some of these factors include:
1. Electrical Ground Issues: Electrical ground issues can cause Code P0A8A. When there’s a bad connection or ground wire issue, it may result in intermittent electrical current flow, leading to this issue.
2. Damaged Electrical Connections: While driving, your car is subjected to vibrations that may cause electrical connections to come apart. This issue is common in older cars or cars that have been driven for long distances.
3. Low Battery Voltage: If the battery voltage in your car is low, it may cause the 14-volt power module current sensor A circuit to malfunction. In this situation, you may consider replacing the battery.
4. Damaged 14-volt Power Module Current Sensor A Circuit: This is yet another common cause of OBD-II Code P0A8A. A damaged circuit can impact the ability of the sensor to measure electrical current flow, causing P0A8A.
How to Repair OBD-II Code P0A8A – 14 Volt Power Module Current Sensor A Circuit Intermittent
To repair OBD-II Code P0A8A, you need to determine the cause of the issue. Here are some repair options based on the likely cause of the issue:
1. Inspect Electrical Ground Connections: If you suspect that the cause of Code P0A8A is an electrical ground issue, you may consider inspecting the ground connections to rectify the issue.
2. Check Electrical Connections: You can also check for any loose or damaged electrical connections around the 14-volt power module current sensor A circuit. If there’s any issue, take steps to rectify them.
3. Replace Damaged Parts: If the cause of the issue is a damaged circuit or sensor, consider replacing the damaged component with an OEM replacement part. This option often fixes the issue.
4. Replacing Battery: If the battery voltage is low, it’s advisable to replace the battery to rectify the issue.
