Order of inspection
P0101 Mass or Volume Air Flow Circuit Range/Performance Medium
The P0101 code means the computer compared the airflow reported by the MAF sensor with the airflow that should exist based on rpm, throttle position and manifold pressure, and the two do not agree. In most cases the sensor is not bad: it is dirty, or air is getting in without passing through it.
