 <<See All OBD Codes

Do you know how the P2A06 error is stored in the vehicle? Keep reading further as you have landed up in the right place. The performance of the engine which is reduced is usually known as the O2 sensor negative voltage bank 1 sensor 1. The main aim of the oxygen sensor is to calculate the oxygen content in the exhaust gases once they are out of the combustion process of the engine. This information might be serious to the PCM’s ability to keep up with efficient fuel economy. If a fault is found by the PCM in the sensor or the information from the sensor, then the P2A06 error will be set in the vehicle.

The O2 sensor negative voltage signal is carefully looked after by the engine control module. The error code will be set in the vehicle by the ECM if the O2 sensor negative voltage goes out of factory specification.

What causes this problem with the O2 Sensor Negative Voltage Bank 1 Sensor 1?

• Malfunctioning of the O2 sensor bank 1 sensor 1.
• O2 sensor bank 1 sensor 1 harness might have a short circuit or you might find an opening.
• The electrical connection might be poor in the circuit of the O2 sensor bank 1 sensor 1

1. Oxygen Sensor - Does your engine misfire very often? Then it is a sign of a faulty oxygen sensor which needs quick replacement to avoid P2A06 error.
2. Engine Control Module Engine stalling is one of the symptoms for a defective ECM which needs replacement as soon as possible.
3. Powertrain Control Module - A faulty PCM can cause misfiring issues and the engine behavior might also be erratic. If your vehicle is causing misfiring issues, then it is because of a faulty powertrain control module. Shop them from Parts Avatar at best prices online.

It is essential 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 P2A06 here:

Common Symptoms

• The engine performance might be reduced.
• Use of fuel consumption might be more.
• Either the engine light or the service engine soon warning light might be on

Here are some ways with the help of which you will be able to correct the OBD Code P2A06

The defective oxygen sensor has to be fixed.

• Its, always best to leave it to the professionals. But if you're confident enough to replace and repair the parts, you can carry out by self.
• If you are carrying out repair works, you will need replacement equipment and tools which are expensive to carry out this process.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2A06 code to be stored:

• This is a general type of trouble code and it is not difficult to diagnose or repair this error.
• It’s always best to give it to the professionals or technicians as they know the tactics to resolve this error where they will connect a scanner to the diagnostic port and recover the stored codes and freeze frame data.
• This can be highly beneficial to know if the error was erratic.
• Once every error codes are cleared, test drive the vehicle.
• Performance issue can rise in the vehicle if the oxygen sensor and fuel injector are faulty. The mechanic will address them first.
• Rarely, the mechanic will check the engine control module as well as the powertrain control module as they might be faulty. If they are found to be defective, it will be quickly replaced.
• If this error code has been made alright, then the mechanic will look for other error codes and address them first, before starting to diagnose the error code P2A06.
• After every diagnosis, the mechanic will reset the code, test drive the vehicle to see if the error code is still stored. Also, this will help the mechanic to know as to where the error occurred.

Common Mistakes When Diagnosing the P2A06 Code

• PCM might be defective.
• There might be some faults with the electrical wires.
• Oxygen sensor might be defective.
• Outflowing exhaust.
