CAR Mass air flow sensor (MAF)

Air-flow meter: common defects and their signs

  1. Wear of conducting paths
    • Engine operation is unstable at idling.
    • Sometimes it is impossible to start the engine.
    • Car dynamics is worsened.
    • Engine power decreases.
    • “Check Engine” indicator is lit on the dashboard.
  2. Soiling
    • Idling rpm becomes too high or low.
    • From time to time the engine turns off unpromptedly, particularly at braking.
    • Jerks and pushes are noticeable during car driving.
    • Fuel consumption increases.
    • Deposit can be seen on the part during visual inspection.

How to repair or replace air-flow meter?

Inner components of the air-flow meter are not subject to repair. For restoration of component operability you should restore solidity of contacts connection or clean the part from dirt with the help of pressed air or special cleaners. This can be performed single-handedly, but you need to be careful, as the sensor is a quite fragile part and even slightest mechanical force can lead to its damaging.

In most cases a defective meter should be replaced. This can be performed without car service station assistance. For different cars theactions algorithm may have its peculiarities, but generally it includes the following:

  1. Open the bonnet and disconnect the battery negative terminal.
  2. Find the air-flow meter in the under-bonnet space, loosen its fastener and disconnect the wires socket from it.
  3. Loosen the clamp on the pipe, coming to the air filter, and then pull it and move aside.
  4. Loosen bolts fastening the air-flow meter and demount the defective part.
  5. Install a new component into the car and perform unit assembling in the reverse order.

During component replacement inspect the air filter visually, and replace it if soiling or mechanical damages are found. Operation of a defective air filter leads to fast soiling and breakdown of the air-flow meter.
