An engine system-monitoring feature that employs a hotwire-sensing device positioned between the air filter and the throttle body to measure the rate of airflow into the engine. This information is fed into the Electronic Engine Control system, which then automatically adjusts the fuel flow to provide more efficient combustion The mass airflow sensor provides precise air metering for better engine performance, greater fuel efficiency and reduced exhaust emissions

This information is used by the engine computer to monitor engine load (vacuum drops when the engine is under load or at wide open throttle). When the engine is under load, the computer may alter spark timing and the fuel mixture to improve performance an

A sensor in the air intake that measures the amount and density of air entering the engine for fuel and spark management. ( Tricked Out episode 102)
