Introduction
The mass air flow sensor measures the amount of air entering the engine. When the MAF sensor does not work correctly, the engine computer miscalculates the amount of fuel for the engine leading to several possible driveability issues.
The sensor is located between the engine air filter and the intake manifold of the engine, on the backside of the air intake box.
This manual will show how to replace the MAF sensor through a disassembly of the air intake box.
