A Breath of Fresh Air: 8-Pin Mass Airflow Sensors

· The 8-pin sensor is typically a hot-wire design. As with many other MAF sensors, the ECM monitors the current flow through the sensor to determine how much air is flowing into the engine. What has changed is the addition of the humidity sensor, BARO sensor, and an additional temperature sensor to measure the air temperature at the humidity sensor.

Hot Film Mass 5 (HFM5) Air Flow Sensors - Autologic

When testing a mass air flow sensor, wide open throttle (WOT) snap the or perform a WOT test drive (accelerate from a stop and accelerate WOT until max RPM is reached. Usually by the second gear shift). Do not perform this test during unsafe or on roadways with other vehicles. Do not exceed posted speed limits. You will want to monitor the sensor signal under all RPM ranges of the test cycle.
