OPERATION
The Mass Air Flow (MAF) sensor is no longer functional in this vehicle. Power to the Air Flow Meter Relay has been disconnected. The Engine
Control Module (ECM) has connections to the MAF sensor but it does not receive any input from this circuit.
The Manifold Air Temperature (MAT) sensor (which is a part of the MAF sensor assembly) still remains functional.
