Error Code P0A86: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0A86 can be explained as 14 Volt Power Module Current Sensor Circuit. If the ECM would detect an unusual voltage within the 14-volt power module current sensor circuit, then the P0A86 error code would start appearing. This would illuminate the check engine light or the transmission warning lamp.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0A86 error code? This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

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

• 14 Volt power module current sensor might be flawed
• 14 Volt power module current sensor harness is not shut or tiny
• 14 Volt power module current sensor circuit might have bad electrical connection
• An update for 14V power module software required
• Low voltage systems might not be working
• Broken battery

1. Powertrain Control Module - A faulty Powertrain Control Module can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Power Module Current Sensor - If everything is alright with PCM, then there is surely some defect in Power Module Current Sensor. Get it replaced before the situation gets worse.
3. Engine Control Module - P0A86 code can display due to some faults in the Engine Control Module. So, it is very important to replace the Engine Control Module with us at equitable prices.
4. Car Battery - Do you remember when was the last time you got your car Battery checked up? A dirty Car Battery can cause a lot of issues like displaying P0A86 code.
5. Power Module Current Sensor Harness - Poor Power Module Current Sensor Harness can cause a lot of difficulties, so why not get it replaced at time?
6. Hybrid Battery - There can be some issues with the Hybrid Battery due to which you may see P0A86 code appearing over and over again. Visit us to buy best quality Hybrid Battery online.
7. Electronic Control Unit - Are you facing some faults in your Electronic Control Unit? Don’t worry and get them replaced or else P0A86 code can turn up.
8. Body Control Module Component - Common cause behind this P0A86 error code can be some fault in Body Control Module Component. So, it will be a good decision to replace them now.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0A86 here:

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

• As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
• After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
• Note down this information as it can clearly help for further diagnosis.
• The mechanic will also inspect the shift solenoid to find if it is disconnected or if any other faults persist.
• After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
• He will know that an intermittent condition persists, if the code does not return instantly.
• But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.
• If any of the component is damaged, the mechanic will replace them quickly.
• Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

Common Mistakes When Diagnosing The P0A86 Code

Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one doesn’t follow all the steps carefully. In this code usually people replace 14 Volt power module current sensor without even properly diagnosing it.

The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
