The Mass Air Flow Sensor (MAF) of GMC Terrain vehicles has an essential function of regulating the quantity of air that gets into the engine. This information is then received by the power train control module (PCM) that then adjusts the fuel injection timing for the required air/fuel mixture. The Mass Air Flow Sensor is an air mass sensor that is able to change its performance depending on the temperature and pressure of the air, which makes it a better option that the volumetric flow sensors. The Mass Air Flow Sensors used in GMC Terrain vehicles have included Vane Meter (VAF) and Hot Wire sensors. The VAF sensor while useful tends to interfere with airflow and can wear out mechanically. On the other hand, the Hot Wire sensor provides higher accuracy and flexibility and it may be influenced by contamination. Other flow sensors including Hot Film and Karman vortex sensors are also available in the market and each of the sensors use different tactics to measure the airflow. These sensors need proper care for them to work as expected and this is where regular maintenance comes in.
