Business services is a general term that describes work that supports a business but does not produce a tangible commodity. Information technology (IT) is an important business service that supports many other business services such as procurement, shipping and finance.
A mass airflow sensor. A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure.
1 Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. 2  Inspect for any air leaks near the MAF sensor. 3  Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. 4  Be gentle with the sensor.
