—INTRODUCTION: Mass Air Flow Sensor (MAF) determines the mass of air entering a vehicle's fuel injection engine, and passes that data to the engine control unit. This balances the air and fuel ratio to promote successful combustion. When the MAF Sensors goes bad, it can lead to various symptoms, ranging from an illuminated check engine light to rough running and misfiring.

—FEATURE: Precision-manufactured and assembled sensing elements are used for precise air flow measurement to restore your car's original driving performance; Qualified equipment and advanced testing, plus 109% strict quality inspection, ensure an impeccable customer experience; Fast response, high durability; Light and portable, easy to install & clean, and can be replaced directly.

—FITMENT: Replacement MAF Sensor Compatible for Pontiac, Oldsmobile, Hummer, Isuzu, Saab Vehicles: 2002 - 2006 Escalade, ESV, EXT & 2002 - 2006 Avalanche 1500, 2500 & 1999 - 2006 Silverado 1500 & 2007 Silverado 1500 Classic & 2000 - 2006 Suburban 1500, 2500 & 2000 - 2006 Tahoe & 2003 - 2009 Envoy & 1999 - 2004 Sierra 2500 & 2000 - 2006 Yukon, XL 1500, 2500 & MORE. See below for the full vehicle list.

MAF (mass air flow) sensors are located between the air filter and the throttle body and are responsible for measuring the amount of air entering the engine. It is part of your vehicle’s electronic fuel injection system. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. You may also notice you’re filling up at the gas station more than usual.

A contaminated or failed MAF sensor cannot measure the amount of air flow correctly.This causes engine computer to miscalculate the amount of injected fuel. As a result, a bad sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty sensor might cause Check Engine or Service Engine Soon light to come on. Make sure to fix the problem right away so you can be safe, avoid costly repairs and avoid being stranded on road.
