Mass Airflow (MAF) Sensor

MAF sensor is located between air cleaner and throttle body. MAF sensor consists of a thermal resistor, metering duct and control circuit. Sensor uses thermal resistor to detect amount of air drawn into engine and sends information to PCM as a current signal. PCM uses this signal to control fuel injectors.
