P0A93 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0A93 can be explained as Inverter “A” Cooling System Performance. The high-voltage direct current of the HV battery is converted by the inverter into the alternating current for the MG1 and the MG2. Heat is generated by the inverter during the process of conversion and it can also damage the inverter if there is no availability of the cooling system. Alike to the MG1 and the MG2, a cooling system used to cool the inverter. It would consist of an electric water pump, cooling fan, and radiator. This cooling system would be self sufficient of the engine cooling system.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0A93 error code? This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Inverter “A” Cooling System Performance?

• The inverter cooling system might not be functioning properly
• Inverter cooling system harness might be opened or at times it can be shorted
• Unsatisfactory electrical connection in the inverter cooling system circuit
• Some issues related to the water pump with motor assembly
• Defective cooling fan motor
• Unusable No. 2 cooling fan motor
• Quirks in the inverter with converter assembly

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.
• 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 persist, 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.
• The transmission fluid can be dirty or there can be any blocks in the transmission filter which can be replaced instantly.
• At times, the fluid level will be insufficient which has to be fixed immediately. If he comes across any leaky areas, he will fix them too.
• Once the fluid is checked for appropriate level, then every other components like wires and connectors have to be checked for possible damages.
• If any of the component is damaged, the mechanic will replace them quickly.
• In this scenario, the error code mostly arises due to a dirty transmission fluid where it can also be contaminated or the shift solenoid is broken.
• 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 P0A93 Code

Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully. In this code usually people replace inverter cooling system 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.
