What Is a Mass Airflow (MAF) Sensor?
The MAF sensor helps your engine breathe correctly — and is a common fault. A Cranbourne West specialist explains.
What it is & what it does
The mass airflow (MAF) sensor measures how much air is entering the engine so the computer can match the right amount of fuel. Accurate readings mean smooth running and good economy.
It can become dirty or fail over time, sending wrong readings.
Signs of trouble & how we help
A faulty MAF causes rough running, hesitation, power loss, poor economy or a check-engine light. Sometimes cleaning the sensor helps; sometimes it needs replacing.
We read live MAF data to confirm it’s the sensor (not another fault) before replacing it.
