More About Our Mass Air Flow (MAF) Sensors

More commonly known as MAF sensor or air meter, the mass airflow sensor has one very important job; measuring the amount of air entering the engine for an optimal air-fuel ratio. Without this information, the ECU will not be able to accurately control fuel injection, resulting in an engine that will either idle roughly, or worst case, not at all. But don’t worry! We’ve been producing OE MAF sensors since the 1970s.

Tech Tips

Why Do MAF Sensors Fail?

Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling or even stalling. There may also be a more frequent need to refuel.

Greener and Less Costly – Installing a MAF

Delphi offers a MAF sensor probe as a greener, less costly alternative to the traditional MAF assembly repair (where applicable).

In most cases it's unnecessary to replace the complete part since it‘s the electronics on the sensor probe that fail 98% of the time. By eliminating the need to replace the plastic housing, Delphi is providing a greener, more cost-effective approach to repair.

Why Choose Delphi MAF?

You won’t find any remanufactured MAF sensors in a Delphi box. Even better, all parts are tested and calibrated to OE standards using highly accurate OE equipment. By testing to OE specifications, Delphi helps ensure that the sensors provide accurate readings and airflow output, which helps to reduce comebacks.
