Cadillac DeVille automobiles utilize the MAP Sensor that measures the positive air pressure that is drawn into the intake manifold and feeds the information to the ECU for fuel modification. The MAP Sensor helps in deciding air density in fuel-injected engines to develop the required air-fuel mixture proportions for combustion. MAP or mass airflow (MAF) sensor can be used in DeVille models with the forced induction engines requiring both. Remotely, the fact that the MAP Sensor takes part in OBD II and its capacity to transforms the data to air mass with the help of an IAT sensor also prove that the sensor is of enormous importance in engine performance.
