Chevrolet Trailblazer Mass Air Flow Sensor

The Mass Air Flow Sensor (MAF) is a component of Chevrolet Trailblazer vehicles that is used to control air intake into the engine to enhance the performance of the engine. All this information is sent to the Powertrain Control Module that would then regulate the fuel injectors to get the proper air-fuel mixture. The Mass Air Flow Sensor can be of two types; Vane Meter (VAF) and Hot Wire sensors where the two employ different methods to measure airflow. The VAF sensor uses a spring loaded vane while the Hot Wire sensor is based on the current variation of a heated wire in the airflow. Although the Hot Wire sensor is more precise than that of the Thermo Anemometer, both kinds are prone to be influenced by contamination. The proper functioning of the Mass Air Flow Sensor is therefore very important and to achieve this, it has to be serviced frequently since a faulty one leads to poor acceleration, stalling and improper ratios of air to fuel.

Each OEM Chevrolet Trailblazer Mass Air Flow Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
