Shopping for a chevy Malibu sensor? The Spectra Premium Mass Air Flow Sensor MA339 measures the mass of air entering the engine and reports it to the ECM, so the computer can calculate the correct amount of fuel to deliver. It installs as a direct-fit replacement for the listed applications, including the 2004-2008 Chevrolet Malibu [L4-2.2L], 2004-2006 Chevrolet Colorado [L4-2.8L, L5-3.5L], and 2004-2007 Saturn Ion [L4-2.0L].
If a failed mass air flow sensor is the cause of a rough idle, hesitation, stalling, or a check engine light, replacing it with the MA339 restores proper airflow readings. Diagnose the cause before replacing. Additional fitment: 2004-2005 Chevrolet Classic [L4-2.2L], 2004-2007 GMC Canyon [L4-2.8L, L5-3.5L, L5-3.7L], 2006-2007 Hummer H3 [L5-3.5L, L5-3.7L], 2006 Isuzu I-280 [L4-2.8L], and 2006 Isuzu I-350 [L5-3.5L].
