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 ...

How to Troubleshoot a Mass Airflow Sensor AxleAddict

· Question: My mass air flow sensor on an 88 Camaro reads 5volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn''t the mass air flow sensor dictate the voltage going out to the ECM? While plugged in, there is erratic nondetectable voltage, on/off, on/off. My ground tests good, and I have excellent battery voltage on ECM side of the …

Building a Flow Bench : 10 Steps Instructables

In order to obtain usable flow data from the flow bench, we utilized a mass air flow sensor (MAF). Specifically, a used MAF from a Volvo S80 that we purchased from ebay. For this project, one could utilize any functional mass air flow sensor; our choice of sensor was dictated by availability on the used market and access to the manufacturer’s datasheet. This document contains the necessary calibration data so that the analog output voltage of the sensor can be correlated with the air mass ...
