A quality MAP sensor is crucial to your engines performance. These sensors will respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal ranging.? The Manifold Absolute Pressure Sensor, also known as the MAP sensor, measures atmospheric pressure inside the intake manifold and sends a voltage signal to the Engine Control Module (ECM). As atmospheric pressure inside an intake manifold is negative during vehicle operation, the sensor is actually measuring vacuum. The ECM calculates proper air/fuel ratios, idle speeds, and ignition spark timing based in part on the Manifold Absolute Pressure Sensor's signal.FULLY COMPATIBLE MANUFACTURED TO OE SPECIFICATIONS FOR FORM, FIT, AND FUNCTIONQuality Tested to Ensure Long-Lasting PerformanceFITS:BUICK PARK AVENUE 3.8L 2004-2005BUICK REGAL 3.8L 2004CADILLAC STS 4.4L 2006-2009CADILLAC XLR 4.4L 2006-2009CHEVROLET COBALT 2.0L 2005-2007CHEVROLET IMPALA 3.8L 2004-2005CHEVROLET MONTE CARLO 3.8L 2004-2005CHEVROLET SILVERADO 2500 6.6L 2002-2004CHEVROLET SILVERADO 3500 6.6L 2002-2004GMC SIERRA 2500 6.6L 2002-2004GMC SIERRA 3500 6.6L 2002-2004PONTIAC GRAND PRIX 3.8L 2004-2007SATURN ION 2.0L 2004-2007
