Mass Air Flow (MAF) Sensor: Description
WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
- The sensor directly measures the mass of the air flowing into the engine.
- The sensor output is a D.C. (analog) signal ranging from about 0.5 volts to 50 volts used by the PCM to calculate the injector pulse width.
- For transaxle strategies, this sensor is used for EPC pressure control, shift and torque converter clutch scheduling.
