How to replace the Mass Air Flow Sensor on GMC Yukon?

You should handle the Mass Air Flow Sensor/intake air temperature (MAF/IAT) sensor with care while replacing it to protect the honeycell at the air inlet end and preserve the sensing elements from any contact with cleaning solvents or lubricants. A small amount of non-silicone lubricant will help with air duct installation. The air cleaner outlet duct must be removed first before extracting the gray connector position assurance (CPA) retainer and disconnecting the Mass Air Flow Sensor/iat sensor electrical connector through pushing down on the black clip. The technician should remove the air cleaner sensor by carefully loosening the Mass Air Flow Sensor/iat clamp before taking the item from the air cleaner housing. Before installing the Mass Air Flow Sensor/iat sensor into the air cleaner assembly guide the embossed arrow towards the engine direction and then secure the Mass Air Flow Sensor/iat clamp at 7 n.m (62 lb in). Connect the Mass Air Flow Sensor/iat sensor electrical connector afterwards reuse the gray cpa retainer followed by reinstallation of the air cleaner outlet duct.

The Mass Air Flow Sensor (MAF) is instrumental in GMC Yukon to take the measurement of air quantity that is let into the engine. The data is transmitted to the Powertrain Control Module (PCM), after which the PCM adjusts the amount of fuel in the injection to make sure that a perfect air-fuel mix is achieved for combustion. GMC Yukons have used different types of Mass Air Flow Sensors; the early models up to 2004 used Vane Meters (VAF) while the later models use Hot Wire sensors. While the VAF sensor works well, there is the propensity for airflow limitation and mechanical degradation. The Hot Wire sensor is more accurate and flexible than the Pitot Tube but its performance can be affected by contamination. There are other types of sensors too, like Hot Film and Coldwire sensors, although they use other approaches to accomplish the same goal of measuring airflow as does the herein described Thru-Flow sensor. Maintenance is vital in the proper functioning of the MAF sensor as used in GMC Yukon cars.
