What is the responsibility of the Mass Air Flow (MAF) sensor?

The Mass Air Flow (MAF) sensor is responsible for measuring the amount of air that enters the engine. It is a hot film type sensor that calculates airflow rate based on the power required to maintain the sensing elements at a fixed temperature above ambient temperature. The MAF sensor has a switched battery feed, a ground, a signal circuit, and a signal return circuit. The PCM reads the voltage signal from the MAF sensor and calculates airflow based on the changes in current draw. To test the MAF sensor, visually check the connector for security and cleanliness, tap on the sensor and wiggle the wires to check for any changes in idle speed, and backprobe the sensor connector using a DVOM set to the Hertz scale to check for a frequency swing when air is blown across the wire. If the sensor is faulty, it may need to be replaced. The removal and installation process involves removing the intake air duct, detaching the MAF sensor electrical connector, removing the mounting screws, and then reversing the procedure to install the new sensor.

Cadillac Fleetwood Mass Air Flow Sensor

The Mass Air Flow Sensor in Cadillac Fleetwood automobiles is one of the most important pieces of equipment in maintaining the right air-and-fuel ratio by measuring the air intake into the engine. This information is sent to the PCM and depending on it, the timing of the fuel injectors is altered to specify the right mix of air and fuel needed. The MAF sensor can be of various types such as the Vane Meter (VAF) and the Hot Wire sensors where each employs different ways of measuring airflow. The VAF sensor uses rotor and stator blades, and consists of a spring-loaded vane on the other hand the Hot Wire sensor is based on the changes in electrical current of a heated wire exposed to the airflow. While, Hot Wire sensor is more accurate than Thermo Cup anisotropy sensor, both can be distorted by contamination and stop working properly. The Cadillac Fleetwood cars require the Mass Air Flow Sensor to be well maintained to meet the diverse demands of driving by performing a scheduled task of timely servicing.

Each OEM Cadillac Fleetwood 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.
