The MAP Sensor in Cadillac DTS is another crucial equipment, mainly responsible for measuring the positive air pressure that is entering the intake manifold with the help of the data that is fed to the engine control unit (ECU) for fuel calibration. It plays a crucial role in defining air-fuel mixture that is required to burn in an automobile engine especially in the speed density model. A MAP sensor or a mass airflow (MAF) sensor could be used for naturally aspirated Cadillac DTS vehicles; both for forced induction engines. The MAP sensor is helpful in the on-board diagnostics also recognized as OBD II, and is an important aspect in the metering of fuels, spark ignition, and in addition to the general performance of the engine through measurement of air mass.
