How to replace the Mass Air Flow Sensor on 2003 Buick LeSabre?

Start by shutting off the ignition before you remove the fuel injection sight shield when replacing the mass air flow (MAF) sensor. The maf sensor electrical connector must be disconnected from its position on the maf sensor that resides on the Throttle Body assembly. The maf sensor requires screw removal before extraction from the Throttle Body. Building the maf sensor involves setting it onto the induction port followed by screw retention while achieving a torque level of 3 n.m (27 lb in). You must reinstall the fuel injection sight shield after reattaching the maf sensor electrical connector to the sensor component.
