![]() ![]() ![]() In this situation, replacing the mass air flow sensor is the best thing to do. However, if after cleaning, the problem persists you might just need to change your airflow sensor completely, the best thing to do is to get a new one. If you don’t know how to clean it, it’s better to take it to a mechanic for them to clean. ![]() However, you are only permitted to clean the mass airflow sensor yourself if you know what to do. The PCM detects that the actual MAF sensor. Basically this P010B diagnostic trouble code (DTC) means that there is a problem with the Mass Air Flow 'B' sensor or circuit. When replacing the air-fuel sensor, make sure the air filter is installed properly to prevent dust intrusion.Ĭleaning the airflow sensor is only a temporary fix. The powertrain control module (PCM) uses that reading along with other sensor parameters to ensure proper fuel delivery at any given time for optimum power and fuel efficiency.Use a cleaner specific to the mass airflow sensor to clean thoroughly.When your mass airflow sensor gets bad, it might be due to dirt so cleaning it should be the best thing to do. Visit your auto mechanic to have the issue resolved as soon as possible Best Things to Do When Mass Air Flow Sensor Gets Bad Jerking and hesitation during acceleration.Decrease in the air fuel ratio (air fuel ratio running lean).Increase in the air fuel ratio (air fuel ratio running rich).That is why it is always advisable to visit your repairman whenever you see your check engine light on. The check engine light could be an indication of anything wrong in the vehicle and not just a bad mass airflow sensor. Check Engine LightĪnother indication of a bad mass airflow (MAF) is when the check engine light is on. This indicates a bad mass airflow sensor. This is also referred to as the air fuel ratio of a mass airflow (MAF) running lean. This simply means there is a significant increase in the ratio of air to fuel, that is, there is more air and less fuel. This means the ratio of air to fuel is tilted towards the fuel side. This is one of the symptoms of a bad mass air flow (MAF) sensor which is sometimes referred to as a situation whereby the air fuel ratio is running rich. Failure to calculate this accurately can lead to transmission problems such as late shifts, early shifts, or even in a worst-case scenario, no shifting at all What are the Symptoms of a Bad Mass Air Flow Sensor? 1. ![]()
