Can a dirty air filter cause mass air flow sensor problems?
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. Also, avoid aftermarket “high performance” air filters that use a coating of oil on them.
How does the MAF work with the O2 sensor?
The MAF is sometimes used in conjunction with an O2 sensor that provides a “closed-loop” feedback in order to make corrections to that predicted air mass. Engines need a proper blend of air, fuel, and combustion to run efficiently.
What can cause a MAF sensor to fail?
The sensor element could get contaminated or damaged. Sometimes, an improperly-installed or ripped air filter can cause the MAF sensor to fail sooner. Over-soaking a washable air filter with oil can also cause troubles with the air flow sensor.
What causes problems with the mass air flow sensor?
Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and cause problems. Sometimes the debris can fall in during the air filter replacement. In this case, the repair is easy.
How does the MAF work in an engine?
The MAF sends its measurements to an engine control unit (ECU), which then uses that data to calculate when to deliver fuel, how much, and when to generate a spark. The MAF is sometimes used in conjunction with an O2 sensor that provides a “closed-loop” feedback in order to make corrections to that predicted air mass.

What happens when a mass air flow sensor goes bad?
This causes the engine computer to miscalculate the amount of injected fuel. 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.
