Can MAF sensor cause loss of power?
Mass Air flow Sensor (MAF). As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.
Does mass air flow sensor have fuse?
There is a fuse for the maf sensor, but it is not the same one that runs most of the other stuff on that side of the engine bay. The code you get is for a dead maf, usually when the fuse pops.
What should I do if my MAF sensor is leaking?
1. Find and eliminate all external air or vacuum leaks downstream of the MAF sensor. When in doubt, use a smoke machine, or lightly pressurize the intake manifold and spray with a soap & water solution. 2. Verify that the manufacturer-specified PCV valve is correctly installed and functioning as designed.
What is the mass air flow sensor number?

What are the different types of MAF sensors?
While there are several distinct MAF sensor technologies ranging from hot-wire or hot-film to Karman vortex and Corialis sensors, and while MAF sensor outputs may take the form of variable frequency, variable current or a simple analog voltage, the diagnostic principles remain largely the same.
