Auto part – Mass Air Flow sensor / Airflow Meter / MAF for 1994-1997 Ford Aspire and 1995-1998 Mazda Protege models.
This is a refurbished and tested unit. Since this unit is a refurbished unit from a New Old Stock (NOS), it may have some marks or scratches, but it is in perfect working conditions and has not been used since it was refurbished and stocked.
The part number of this unit is 74-10023 from Cardone or 336-60209 from Hollander.
Other part numbers. The following are interchangeable part numbers that this part replaces:
- 213-3350
- 790-21001
- 917-896
- 207074
- 221001M
- AF10327

NOTES:
- 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.
- 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.
- Do not use octane booster products. It is known that those products may cause harm to sensitive electronic fuel injection systems sensors and parts.

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.
