Where is the maf sensor located on a 2003 Mazda 6?

The Mass Air Flow (MAF) sensor on a 2003 Mazda 6 is typically located in the intake air duct between the air filter and the throttle body. It's usually housed within a plastic housing and is connected by an electrical connector. To access it, you may need to remove any air intake components that obstruct the sensor. Always ensure the engine is off and cool before attempting to inspect or replace the MAF sensor.
