Often the code P0101 is caused by a vacuum leaks. A vacuum leak allows “unmetered air” to enter the engine by-passing the airflow sensor. In the top photo, you can see a cracked intake rubber duct (snorkel).

How do I reset my mass airflow sensor?

Upon replacing the Mass Air Flow Sensor, turn on the engine light to ensure it still has its function. You can unhook the battery and leave it unhooked for 10 minutes to completely reset the entire system. The battery will not harm itself if left unhooked for more than 10 minutes.

Can a dirty air filter cause a mass air flow sensor?

Symptoms of a dirty filter

The air filter may be the MAF sensor’s first line of defense via the engine’s air intake system, but a clogged, low quality or dirty air filter can actually become the source of MAF sensor damage if any contamination bypasses it.

Should I disconnect battery when changing MAF sensor?

The original mass air flow sensor needs to be removed. A. The battery needs to be disconnected from the ground cable. Accidental starting and injury are prevented by this.

What causes MAF sensor failure?

Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling, poor acceleration or even stalling.
