Faulty mass air flow sensor problems hot film

If you suspect a MAF sensor problem, scan for any fault codes. A MAF problem should (but does not always) set a fault code.

ECU is unable to compensate the differences in air/fuel mixture. The other cause is the Mercedes air mass meter.

A hot-film MAF sensor targets 1degrees F higher than the incoming air temperature while a hot-wire MAF sensor is heated to an additional 2degrees F above the surrounding air. Air from the engine’s intake system passes the sensing element, cooling it so that more electrical current is required to maintain the target temperature.

The hot film MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal. This sensor uses a hot film-grid instead of a hot wire.

Mass Airflow MAF Sensors - Auto Diagnosis Repair Help

I go over the symptoms of a dirty or bad Mass Air Flow Sensor like hesitation, rough idle or lack of power. But also I show you how to properly clean a MAF sensor and exactly how a hot wire Mass Air Flow Sensor and an Inlet Air Temperature (IAT) Sensor works as well.

MAF if you have a random or intermittent misfire, loss of power, etc.I personally tried and the engine runs on 95/99/ 03/audi, and the list goes on.

All modern VW, Audi, and TDI use a MAF to help measure air flow. A MAF sensor is one way of directly measuring how much air is passing the MAF sensor and into the engine.

MAF issue on a VW has been to just clean it. Of course, you have to keep in mind that a dirty VW MAF sensor will not cause a lot of havoc.
