Air flow sensor (MAF / MAP)

VOLTREK air flow sensors measure the mass or pressure of the air entering the engine for accurate fuel metering.

VOLTREK air flow sensor with housing

The amount of air entering the engine is the base value for fuel metering. A MAF (mass air flow) sensor measures the air mass directly in the intake duct; a MAP (manifold absolute pressure) sensor measures pressure in the manifold and the control unit calculates the mass from it. An inaccurate sensor causes high consumption, smoke and loss of power.

VOLTREK designs its air flow sensors with a calibrated sensing element, resistance to contamination and vibration, and housing diameter and connector that match the original part.

Frequently asked questions

MAF or MAP: which sensor does my vehicle have?
A MAF sensor measures air mass in the intake duct; a MAP sensor measures pressure in the manifold. Some engines have one, some both. The OE number on the existing part settles it immediately.
