What is the code for mass air flow?
My 2013 Sentra SR has the same code p0101 for Mass air flow. I cleaned the sensor and CEL went off for a while but came back recently. My PCV is orange, should I replace with a new black pcv or new orange Pcv??
What to do if you get a bad MAF code?
IF you get another MAF code with the new sensor and after batt disconnect… Your air filter is clogged. If the new MAF doesnt detect proper airflow it will register as a bad MAF. I would remove or replace your air filter and test…straight away.
Why is the Check Engine light still on after cleaning mass airflow?
If it is the MAF, and cleaning it was unsatisfactory, it will be need to be replaced. There are many possible causes for the Check Engine Light to come on besides the mass airflow sensor, so have an expert read the codes and address the Check Engine Light accordingly. Was this answer helpful? Thank you for your feedback! Sorry about that.
What should I use to clean my MAF sensor?
Use mass air flow sensor cleaner (DO NOT SUBSTITUTE FOR ANY OTHER KIND OF CLEANER) to clean out the MAF sensor. Do this by spraying each side of the MAF sensor for 3-5 seconds, waiting 10 seconds, and then spraying it again for 3-5 seconds.
What are error codes for mass air flow sensor?

How to clean a dirty mass air flow sensor?
How to clean a Dirty mass air flow sensor. Sometimes you may be able to extend the life of the mass air flow sensor by cleaning it. As explained above, the sensor can become covered in grease and dirt and this can affect its performance. In my experience, if the engine is performing very badly, then the sensor may be worn as well as dirty.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
