The Benefits of Cleaning Your Mass Air Flow Sensor. The more oil and dirt that accumulates on your MAF, the worse it serves its purpose. The dirtier it gets, the less accurate the reading it sends to your ECU (computer). These readings can cause lower gas mileage and a small loss of power.
The hot wire or film element is dirty or damaged so that it is unable to ''feel'' air flow. The sensor selfcleaning electrical circuit (on hotwire types) has failed. The most common cause of MAF sensor failure is a dirty sensing element. Depending on your specific results, you may want to check the sensor itself:
· VW Mass Air Flow (MAF) Sensor Test (5 Wire Type) The most common way to test the 5 wire VW Mass Air Flow (MAF) sensor is just to unplug it with the engine running. If the MAF is bad (either because it''s not producing a signal or producing an erratic one), the car''s idle will return to normal and the car will seem to run fine.
· Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.
With a lab scope a Mass Air Flow (MAF) sensor is measured under the following conditions: key on, cranking, idle, 2000 RPM, 3000 RPM and back to idle with an engine at operating temperature. The signal from the sensor is shown and can be downloaded.
