The Mass Air Flow (MAF) sensor measures how much air enters the engine.

Your ECU uses this airflow number to calculate:

• how much fuel to inject

• ignition timing adjustments

• idle stability

• emissions control strategy

When the MAF reading is wrong (dirty sensor, air leaks, wiring issues), the ECU “guesses” fuel delivery — and that’s when you get rough idle, hesitation, poor MPG, and the Check Engine Light.

A failing fuel pump can absolutely trigger a Check Engine Light.

The fuel pump is responsible for delivering pressurized fuel from the tank to the engine.
If pressure drops or becomes unstable, the engine may not receive the correct fuel amount.

Modern vehicles detect fuel pressure changes very quickly — even before major symptoms appear.
