Error Code P0A8A: What It Means & What To Do?

<<See All OBD Codes

What does P0A8A error code refer to? Are there any ways to diagnose them easily? What does this error code signify? The 14-volt power module current sensor is carefully monitored by the engine control module (ECM). If the 14-volt power module current sensor does not perform as per the factory considerations, then the engine control module will store the P0A8A error code in the vehicle.

The 14-volt power module current sensor circuit intermittent is generally referred to the low voltage system that does not function properly. The accessory DC power module, also known as the 14V power module carefully looks after the current to the voltage system which is low. If the correct voltage is not identified by the module, then the P0A8A error code will be set by the 14V power module, thus disabling the voltage system that is low.

What causes this problem with the 14 Volt Power Module Current Sensor Circuit Intermittent?

• Power module current sensor might be faulty.
• 14-volt power module current sensor harness has an opening or the circuit might be shorted.
• The electrical connection might be very poor in the 14-volt power module current sensor.
• The software of the 14-volt power module has to be updated.
• Low voltage system will result in improper functioning of the vehicle.
• The battery might be damaged.

1. Power Module Current Sensor - In order to avoid the P0A8A error, the damaged power module current sensor has to be fixed.
2. Power Module Current Sensor Harness - The power module current sensor harness has to be checked if they are proper. If they are found to be faulty, replace them immediately.
3. Power Module Software - A frequent update of power module software is needed to avoid the P0A8A error code.
4. Power Module - The power module has to function normally without any damages so that the P0A8A error code can be avoided.
5. Engine Control Module (ECM) - Do you find the engine control module to be faulty? Is it broken? Get the right replacement for your faulty engine control module from Parts Avatar at the best prices.
6. Car Battery - A swollen or damaged car battery has to be replaced immediately so that the engine functions normally.

Interested in knowing the symptoms to OBD code P0A8A? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with 14-Volt Power Module Current Sensor Circuit Intermittent.

Common Symptoms

• The improper functioning of the low voltage system.
• The engine light remains ON.

• Have a look at some ways with which you can correct the P0A8A code:
• Replacing the power module current sensor.
• 14-volt power module current sensor harness has to be repaired.
• The electrical connection of the 14-volt power module current sensor has to be made alright.
• Changing the swollen car battery.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of power module current sensor, power module current sensor harness, power module software, power module, engine control module (ECM) and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P0A8A fault code:

• The mechanic will need an OBD-II scanner to perform the diagnosis.
• If everything works fine, the mechanic will recover all freeze frame data and stored codes from the vehicle with the help of a diagnostic scanner by attaching it to the vehicle.
• The mechanic will check the power module current sensor to see if it is damaged. If it is found to be defective, it will be replaced immediately.
• Further, he can continue by carefully inspecting other components like power module sensor, power module sensor harness for any possible damages or faults.
• After this, the mechanic will check the power module software to see if it is updated properly.
• As a final step, the mechanic may check the engine control module and as well as the battery if there are any faults or damages.
• Once the repair is done, the mechanic will test drive your vehicle and see, so that he will know if the error code appears again or not.
• This process of repair will be carried out until the error code stops showing.

After it is repaired, the mechanic will again retest the codes and test drive the vehicle. It is always a good habit to retest and test drive the vehicle so that it can help the mechanic with the actual area as to where the fault arose.
