The sensor is a small unit with two exposed wires; the wires heat up when the car is running, and the MAF measures the airflow by detecting how quickly the flow of air cools the temperature of the wires. Spraying these wires clean with MAF cleaner or electrical contact cleaner and leaving the MAF to air dry is the best approach to cleaning this sensitive instrument. Once it is dry, it can be reinstalled and the …

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 …
As a result, a bad mass air flow sensor causes various driveability problems, including a nostart, stalling, lack of power and poor acceleration. Trouble codes P0171 System Too Lean (Bank 1) and P0174 System Too Lean (Bank 2) are also often caused by a bad or contaminated mass air flow sensor.
23/12/2019· The mass air flow sensor is relatively simple. It contains two wires. One is hot and one is cold. The system measures how much energy is needed for the cold wire to feel the heat from the hot wire; a value that is impacted by the amount of air flowing between the two wires, and thus it adjusts the air flow into the engine accordingly.
24/02/2012· When a vehicle''s mass airflow sensor is faulty or defective it can cause a variety of problems, and usually results in very poor performance from your engine. Symptoms of a Faulty Mass Air Flow Sensor A faulty mass airflow sensor will cause problems similar to low compression or low vacuum, and will also show symptoms similar to when your vehicle has low fuel pressure from a faulty …
