Charge Air Absolute Pressure Sensor (603)
The absolute pressure sensor (603) is integrated with the temperature sensor (407) in one component. The sensor (603/407) is located on the charge air pipe.
Pressure given in kPa refers to absolute pressure, i.e. 100 kPa corresponds to barometric pressure at sea level.
When checking the pressure sensor with a pressure/vacuum pump, slightly lower voltages may be obtained at high altitudes.
