You could also find out that your car doesn’t actually have a MAF sensor, but rather a MAP (manifold absolute pressure sensor). You may find on some cars that the Intake Air Temperature sensor is built into your MAF sensor. If you look back from the air filter, it should be located in the housing where the first cable plugs into.įor example, on my Skoda, it’s right after the air box. The Mass Air Flow sensor is located between the air filter and engine intake manifold.
If a dirty MAF sensor is your only problem, once cleaning it, you’ll regain some power, have better fuel economy and it should no longer hesitate under acceleration either. The other more obvious benefit is the fact that your car will begin to perform as it should again. All you need to do is go to your local auto parts store and grab yourself a can, return home, disassemble and then clean the sensor.

My car for example would always hesitate when pulling away and at around 3000 RPMs. This could be anything along the lines of taking slightly longer to start, slightly different idle, decreasing fuel economy, or a hard-to-notice hesitation.Īs the Mass Air Flow Sensor continues to get dirtier these problems will continue to become way more consistent and obvious. These may be inconsistent or something that you just brush off, to begin with. In the beginning, you’ll start noticing subtle performance differences.
