Mass Air Flow (MAF) Sensor
WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The miro-mechanical Mass Air Flow (MAF) sensor is a hot film thermal flowmeter with an integrated temperature sensor which detects the intake air temperature. The sensor is designed for recording load on combustion engines with diesel fuel injection and has a cylinder size in accordance with the required air flow rate. The MAF Sensor is mounted inline in the air intake between the air filter and the turbocharger. See Fig 1.
