Having the exact air-to-fuel ratio is the key to enhancing a vehicle’s overall performance. In particular, such a ratio improves a vehicle’s fuel efficiency, thereby leading to an efficient combustion process. But to achieve this, there should first be a properly working fuel injection system to supply the vehicle with the precise amounts of fuel flow and air flow. One of such valuable parts that make up the fuel injection mechanism is the air mass meter.
The air mass meter, also called the air flow meter, is a sensor device that measures the mass and weight of air entering and flowing through the engine system. Strategically positioned close to the air filter assembly for a thorough monitoring and measuring of incoming air, the air flow meter sends the resulting air calculations to the vehicle computer or engine control unit (ECU). Once such information has been provided, the engine computer then calculates and infuses the proper amount of fuel necessary for an efficient combustion.
Given the importance of the
air mass meter, it is only sensible that the car owner learn the common causes of its malfunction. Its three considered enemies are water, foreign debris, and other forms of moisture and fluid. Thus, it is imperative that car owners be extra careful during cleanup of the engine compartment, as getting liquids or degreasers on the air flow meter may cause it to fail. A defect in the air mass meter is quite easy to detect, as this device causes performance troubles such as a poor idle or a peculiar hesitation when accelerating the car. To make sure that it is really the air mass meter acting up, it is advisable to inspect the performance of the computer diagnostic codes and report any difficulties to a professional mechanic.
Nevertheless, if the air mass meter is beyond repair, the best course of action is to replace it. Settling with a defective one or purchasing a second-rate air mass meter only results in bigger headaches for a car owner. Indeed, an awfully performing air mass meter only harms a car’s fuel economy, as well as the engine’s overall operation.
