P0A08 - OBD Trouble Code

<<See All OBD Codes

What does P0A08 error code refer to? What does the converter status circuit mean? Do you find the DC converter to be faulty? Is there any opening in the DC converter harness?? If there are any of these symptoms, then you may likely find the P0A08 error code stored in your vehicle. If the engine does not start at all, it is referred to as a DC converter status circuit.

Converter status circuit generally refers to the error code where the engine refuses to start. If the engine control module or the powertrain control module finds that the voltage is dropped in the auxiliary battery, then the P0A08 error code will be stored. Malfunction of the DC converter will end up in the vehicle stalling. The high voltage in the hybrid system is converted by the hybrid vehicle converter to 12V so that it can charge the auxiliary battery. Power is supplied to various areas like vehicle lighting, radio and so on by the high voltage system.

What causes this problem with the DC/DC Converter Status Circuit?

• DC/DC Converter might be faulty.
• DC/DC converter harness has an opening or the circuit might be shorted.
• DC/DC converter circuits electrical connection might be very poor.
• The powertrain control module (PCM) might be defective.

1. DC/DC Converter - Does your engine overheat? Then it’s likely because of the faulty DC converter which needs immediate replacement.
2. Engine Wires - Is the engine wire damaged, defective or broken? Don’t worry. Find the replacement for the damaged engine wires from Parts Avatar.
3. Powertrain Control Module - You can easily avoid the P0A08 error code by fixing the faulty powertrain control module with new one from Parts Avatar.
4. Car Battery - Do you hear the cranking noise in your engine? If it’s yes, then you must change your car battery with new ones. Get a new car battery at best prices from Parts Avatar.
5. Converter Assembly - The damaged converter assembly will give rise to the P0A08 error code. Get rid of this error code by getting a new converter assembly at affordable cost from Parts Avatar.

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

• Diagnosing the P0A08 trouble code is not that difficult.
• But it is always great to hand it over to a trained professional or technician as they can easily diagnose this error code.
• If there are any issues with the DC or the DC converter, it will be addressed first. After fixing this issue, the mechanic will check the wires.
• The broken or damaged wiring harness will be replaced with a new one.
• After fixing these issues, if the error still exists, the mechanic will check the VCT solenoid. VCT solenoid may be broken or contaminated and the mechanic will address this issue as well.
• As a very rare case, the powertrain control module or the battery can be damaged or broken. If they are found to be defective, the mechanic will fix them.
• Also, when fixing this issue, the engine must be in a proper condition which means there must be no polluted air in the engine.
• Additional trouble codes like conditions of a misfire, lean running, or polluted air entering the engine and any other issues have to be addressed first, before fixing the P0A08 error code.
