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.

|---|---|---|---|
| Power supply | V | 5 | |
| Voltage at | |||
| 25 kPa (-0.75 bar) | V | approx. 0.9 | |
| 50 kPa (-0.50 bar) | V | approx. 1.3 | |
| 100 kPa (± 0 bar) | V | approx. 2.1 | |
| 125 kPa (0.25 bar) | V | approx. 2.5 | |
| 150 kPa (0.50 bar) | V | approx. 2.9 | |
| 175 kPa (0.75 bar) | V | approx. 3.3 | |
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.
