Keep your engine's fuel calculation accurate with the Standard Ignition Mass Air Flow Sensor MAS0290. It installs as a direct-fit replacement for the 2004-2005 Volkswagen Passat and the 2004-2008 Volkswagen Touareg, dropping into the intake to restore the airflow signal your engine's control module relies on.
- Measures incoming air: reads the mass of air entering the intake and reports it to the engine control module.
- Supports proper fueling: that reading lets the ECM meter the correct amount of fuel and maintain the intended air-fuel ratio.
- Signs this part may need replacing: rough idle, hesitation, poor fuel economy, or an illuminated check engine light — if a faulty mass air flow sensor is the cause, this unit replaces it.
Diagnose the cause before replacing, since these symptoms can have other sources. This is the mass air flow sensor for the listed Volkswagen applications.
