It may also result in rough running stalling or a drop in gas mileage. The mass air flow sensor MAF has two sensing wires but the airflow sensor usually works on hotwire principle. How does the airflow sensor work.
The mass air flow sensor is part of the engines intake system and is located between the air filter and the throttle body. Why Mass Air Flow Sensors Fail. This particle accumulation over time results in poor performance of the sensor.
The engine hesitates or drags while under load or idle. A vacuum leak a clogged air filter restricted exhaust a clogged catalytic converter or a broken intake tube can mimic a bad MAF sensor so check the intake system to rule those issues out first. A bad mass air flow sensor is often the likely culprit if your car isnt running as it should.

The mass air flow sensor is part of the engines intake system and is located between the air.
These issues dont always mean that your MAF sensor is faulty. In such a scenario the ECU will sense the drop in engine vacuum first and then using other sensors data will decide if more fuel is required. The most common signs of bad mass air flow sensor MAF in BMW X3 are loss of power or slow acceleration engine hesitation or jerking during acceleration erratic idling misfires poor exhaust emission values and sometimes black smoke comes out of the tailpipe.
Sensors are in use every time your vehicle is operating. Excessively rich or lean idling. A faulty mass air flow sensor can make it difficult or impossible for the engine control module ECM to calculate fuel injection correctly.
Surprisingly a bad mass air flow sensor can lead to running rich. Stalling jerking or hesitation during acceleration. Ad Genuine Bosch Mass Air Flow Sensor for VWaG 06A-906-461-D.
What are the symptoms of a bad MAF sensor. A car in poor working order shows warnings such as rough idling black smoke emitting the tailpipe or bad fuel efficiency. The sensor can be.
