During a manual pressure sensor calibration, the ECM checks the signal from the atmospheric pressure sensor against an acceptable range of pressures. The barometric sensor, also commonly known as the barometric air pressure sensor (BAP), is a type of engine management sensor commonly found on many vehicles. On mine the atmospheric pressure sensor was going out and would cause the boost pressure gauge to start at a number higher than 0 at idle. A747/GY. The ECM then calibrates the remaining analog pressure sensors against the atmospheric pressure sensor. It is not necessary to remove inlet manifold temperature sensor (1) or inlet manifold pressure sensor (2) . Only 7 left in stock - order soon. G833/PK.
