Charge air absolute pressure sensor (603)

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.

Location



On hose between charge air cooler and throttle body

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.
