Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
Open the hood and locate the air intake system.
Loosen the hose clamps that tighten the air filter to the air intake boot in front of the mass air flow (MAF) sensor/air mass meter.
Inspect the mass air flow sensor/air mass meter wires in a direct light source. Verify any dirty build up that would obstruct the engine computer's reading of the air flow. If cleaning (only) is needed - then use a spray (aerosol) cleaner designated / formulated for mass air flow meters. Use of any other type cleaner may damage the sensor.
Clean the air intake hose - especially on the intake side of the MAF sensor.
Install the new or cleaned mass air flow (MAF) sensor/air mass meter unit. Tighten the sensor bolts.
Tighten all hose clamps and check the entire air intake system for leaks.
