The Mass Air Flow Sensor in Cadillac CTS vehicles is very crucial in the provision of right air/fuel mixture to the vehicle's engine through the calculation of amount of air that enters the engine. This information is communicated to the Powertrain Control Module (PCM), where the fuel injection is controlled in order to allow the right air/fuel mixture for combustion. Different Cadillac CTS Models have used different types of Mass Air Flow sensors such as Vane Meter or VAF and Hot Wire sensors. The VAF sensor is very useful but has the drawback of limiting airflow and is prone to mechanical wear while the Hot Wire sensor offers high accuracy and flexibility but it can be influenced by contaminants. Aside from the types mentioned earlier, others include Hot Film, and Karman vortex sensors, which although using different procedures, provides accurate airflow rate measurement. Indeed, it was established that proper care and functioning of the Mass Air Flow Sensor is central to the correct working of the Cadillac CTS.
