The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. You may also notice you’re filling up at the gas station more than usual. How the MAF …
07/10/2020· The mass air flow sensor measures the air mass flowing into the engine intake. Measuring air mass is critical in calculating how much fuel to add to achieve the correct airfuel ratio (AFR). The ideal AFR is :1 ( pounds of air to pounds of gasoline), but realworld AFR varies. Acceleration might require a rich AFR, up to 12:1, while cruising requires a leaner AFR, sometimes as …

22/10/2018· A bad mass air flow sensor won’t reliably measure the amount of air coming in through the air filter, resulting in a delay in the fuel delivery during sudden acceleration and a temporary lack of power. In such a scenario, the ECU will sense the drop in engine vacuum first and then using other sensors, will decide if more fuel is required. That process could take half a second to a second, more …

17/11/2015· An example of this is the Mass Air Flow sensor or MAF. The job for this sensor is to let the computer know how much air is in the engine. As more comes in, more fuel is also needed to maintain optimal ratios. Without the correct ratio, the engine won’t run. The MAF can become clogged with excessive carbon buildup from the combustion cycle, or sometimes by road grime. If it is too …
10/10/2009· I''ve read some forums and it looks like it might be when the engine goes into "safe mode" and won''t let you rev over 2500 RPM. I have a 2002 Nissan Altima that started having this problem that ...
09/07/2021· In many cars a failed mass air flow sensor can cause a car not to start. The car might start for a second, but stall immediately. Mechanics often use a knowngood mass air flow sensor to test if the engine starts. Some mechanics try disconnecting the mass air flow sensor to see if the car starts without it. Replacing a mass air flow sensor is easy and not very expensive (30160 part …
Symptoms of a bad mass air flow sensor As a result, a bad mass air flow sensor causes various driveability problems, including a nostart, 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.
