DENSO's improved designs in mass air flow sensors utilizes a unique structure that reduces exposure to the sensing unit. This helps to reduce sensor contamination for improved detection accuracy. DENSO also uses a fine platinum wire sensing element coated with a glass film to further protect it from contaminants, resulting in even higher reliability. Protecting the sensor from contaminants will help maintain performance accuracy and extend the life of the sensor.

Check for Vacuum Leaks First!
Vacuum leaks present symptoms similar to a faulty MAF Sensor. When replacing the MAF, always check for vacuum leaks, too. Common sources include:
Leaking Intake Manifold Gasket (found in the "Engine" category) - Vacuum Gauge readings below 17-22 in-Hg (normal manifold vacuum at sea level) at idle may indicate an intake manifold gasket leak.
Note: As elevation increases, readings decrease. Subtract 1 in-Hg from normal manifold vacuum reference for every 1,000 feet increase in elevation above 2,000 feet.
Stuck open PCV Valve - remove the PCV Valve and gently shake it; if it does not rattle, the valve is clogged or dirty and should be replaced.
Cracked Intake Boot (found in the "Engine" category)
