NOTES:

 

  1. It is important to clean the throttle and clean or replace spark plugs after replacing a bad flow meter or MAF to prevent temporary malfunction of the replacement part.
  2. It is possible that a reset needs to be done in your car with a scanner to erase the old trouble codes and check if any of the codes persist.

The function of a Flowmeter or MAF and symptoms when malfunctioning

 

If the flowmeter of your vehicle is failing, this situation will show different symptoms in different car models, but symptoms are all related. For example, the most common are:

 

  • Noticeable lower fuel economy
  • Black smoke or raw fuel smell from the exhaust
  • Engine not starting or hard to start
  • If the engine starts, very rough idle
  • Engine stalling or hesitation
  • Uniform soot/carbon dry stain on all spark plugs
  • Almost always a check engine code will be shown

 

Why does this happen? This happens because the flowmeter or MAF is in charge of metering the incoming air to the engine, so that way, the ECM (Engine Control Module) can adjust the amount of fuel being injected, to keep the ideal mixture needed by the engine, which is near 14.7 parts of air and 1 part of fuel (gasoline) or an air/fuel ratio of  14.7:1.

 

With no accurate measure of the incoming air, no accurate injection will occur, causing the symptoms describes above, among others, from a too lean (poor) or too rich fuel mixture.

 

Are Flowmeter, MAF, MAFS, Mass Air Flow Sensor the same?

 

Yes, it refers to the same part, which is a part used in engines to measure the amount of air entering the engine. The difference is that the earlier designs (flow meters) measured the incoming air in volume (cubic units per minute) and the newer ones, measure the air by mass (weight units per minute), which is more accurate for calculating the air/fuel mixture for the engine. Remember the chemistry class? They often mentioned, “measure the parts in weight instead of volume…”? Well, this is no exception.
