Keep fuel metering accurate and idle steady with the Hitachi Astemo Mass Air Flow Sensor (MPN MAF0034). It drops in as a direct-fit replacement across a wide range of GM-family vehicles, including the 2010-2016 Buick LaCrosse, 2011-2016 Buick Regal, 2010-2015 Chevrolet Camaro, 2006-2013 Chevrolet Corvette, 2014-2019 Cadillac CTS, and 2007-2010 Saturn Vue — 45 applications in all, so check the "Vehicles it fits" section for the complete list.
- Measures intake air mass: monitors the mass of air entering the engine and reports it to the ECU, which uses that reading to deliver the correct amount of fuel.
- Signs it may need replacing: rough idle, hesitation, stalling, poor fuel economy, or an illuminated check engine light — if a failed mass air flow sensor is the cause, this replaces it.
- Direct-fit replacement: a direct-fit replacement for the listed applications.
Diagnose the underlying cause before replacing, since these symptoms can have other sources. Other applications include the 2016-2019 Cadillac ATS, 2005-2010 Chevrolet Cobalt, 2007-2012 Chevrolet Colorado, 2006-2010 Pontiac G6, and 2007-2009 Saturn Aura.
