Mounting Hardware IncludedNo
Terminal Quantity3
Sensor Only
Walker Products new mass airflow (MAF) Sensors are designed to provide the vehicle's Powertrain Control Module (PCM) with precise information regarding how much air is entering the engine, which guarantees ideal engine performance. Walker has been an automotive industry leader in providing high quality fuel system components since 1946.
Replacing the Complete Housing Assembly instead of the Sensor Only ensures the connector air tubes are clean and protects the sensor element, which can be damaged by air pollution or oils on your hands.
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:

  • Cracked or loose Vacuum Hoses / Connectors - an audio Stethoscope can help detect air induced sounds from vacuum leaks.
  • 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)
