How to properly replace the Mass Air Flow Sensor on a Buick LaCrosse?

The first step to change the Mass Air Flow Sensor/intake Air Temperature Sensor starts with turning off the ignition and unscrewing the Mass Air Flow Sensor (MAF) electrical connector. First remove the air cleaner intake duct and after that disconnect the maf sensor fasteners before extracting the maf sensor and maf sensor seal together. You should first position the new maf sensor seal along with the maf sensor before installation. The maf sensor screws should be installed before applying enough torque until they reach 4 n.m (35 lb in). To finish the replacement process connect the maf electrical connector then install the air cleaner intake duct.

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

Start by turning off ignition power before you remove the fuel injection sight shield during mass air flow (MAF) sensor replacement. Throttle Body assembly retains the maf sensor attachment point so users must unplug the maf sensor electrical connector before proceeding. The maf sensor requires removal from the Throttle Body through removal of its securing screws. When installing the maf sensor position it on the Throttle Body and follow the direction noted under service precautions fastener notice. Screw the maf sensor into position using screws that require 3 n.m (27 lb in) torque. The last step is to install the fuel injection sight shield while the maf sensor electrical connector receiving end gets connected to the maf sensor.

How to replace the Mass Air Flow Sensor on Buick Regal?

Start your maf sensor replacement process by taking off the fuel injector sight shield. The maf sensor connects to the Throttle Body assembly thus begin by disconnecting the maf sensor electrical connector and unscrewing the maf sensor screws. You must remove the maf sensor following its screw removal. Start installation by repositioning the maf sensor according to the notes in service precautions fastener section. Tighten the maf sensor screws by using torque 3 n.m requiring 27 lb in of force. Reinstall the fuel injector sight shield once you have reconnected the maf sensor electrical connector and reinstalled the maf sensor screws .
