WHAT IS A MASS AIR FLOW SENSOR?
The mass air flow sensor (MAF) is a key component of the electronic fuel injection system in a car. It is located between the air filter and the engine's intake manifold. In some cars, the intake air temperature (IAT) sensor is built into the mass air flow sensor. However, there are various types of air flow sensors and all require different maintenance. Digital sensors send a frequency output, while analog mass air flow sensors produce a variable voltage output. Both outputs are sent to the engine control module to help regulate air-fuel mixture in the car's automatic transmission system.
WHAT DOES IT DO?
Mass air flow sensors measure the air mass flowing into the engine intake. This is important for calculating the amount of fuel to add to achieve the proper air-fuel ration (AFR), Ideal AFR is 14.7:1 (14.7 lb of air to 1.0 lb. of gasoline), but AFR can vary. Acceleration requires AFR of up to 12:1, while cruising requires levels as low as 22:1. A faulty mass air flow sensor can make it difficult or impossible for the engine control module (ECM) to calculate fuel injection correctly. This can cause a myriad of other problems for your vehicle.
