Hi,my name is mike and I will assist you with your question.
This issue that you are having and the code that you are getting is because the mass air flow sensor is failing. The mass air flow sensor is responsible for measuring the air/fuel mixture to the engine. To correct the issue the sensor has to be replaced and this is likely unrelated to the original problem.
