3 Signs of a Bad Mass Air Flow Sensor

  1. Stalling, jerking, or hesitation during acceleration.
  2. air fuel ratio is too rich.
  3. air fuel ratio is too lean.

What happens when air flow sensor goes bad?

A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.

How do I reset my air flow sensor?

Check if the engine light is still on after the Mass Air Flow Sensor was replaced. The entire system can be reset by unhooking the battery and leaving it unhooked for 10 minutes. Keeping the battery unhooked for longer than 10 minutes won’t hurt anything.

How to replace the MAF sensor on a Mercedes W210?

Release the two clips on the top and bottom of the MAF sensor housing (green arrows). Pull the end of the MAF sensor housing out of the airbox. Loosen the hose clamp on the other end of the MAF sensor housing to release in from the intake hose (green arrow). Pull the MAF sensor housing out of the intake hose.

How does the mass air flow sensor work?

The mass air flow sensor senses the total amount of air passing the sensor and allows the fuel injection system to adjust the fuel mixture to compensate for cold weather and/or high altitude conditions. The MAF also incorporates an internal intake air temperature sensor which measures the temperature of the intake air.
