Genuine Saturn LS MAP Sensor

Saturn LS is equipped with the MAP Sensor, which is a significant device for measuring the positive air pressure, which enters into the intake manifold. This small device sends information to the engine control unit (ECU) so that it mods fuel injectors depending on the volume of air in the cylinders so that it can regulate the air-fuel ratio for the combustion process. In naturally aspirated engines, the MAP Sensor is mostly used in Saturn LS models, it can be installed jointly with the mass airflow sensor (MAF). The MAP Sensor is based on the speed-density principle and, thus, constantly delivers pressure data that affects fuel and ignition maps. While boost sensors gives negative pressures the MAP Sensor only deals with the absolute pressure hence it is not susceptible to giving negative pressures. This functionality is critical to the performance of an engine and the DIAG4 system in that it includes on board diagnostics, especially when testing the EGR valve.
