Fuel Pressure Sensor - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

Fuel Pressure Sensor

Fuel pressure sensor on the center of common rail detects instant fuel pressure changes and then sends to ECU. When
received these signals, ECU uses them to control fuel volume and injection time.
The fuel in the rail reaches to sensor diaphragm via blind hole in the pressure sensor and the pressure signal converts to
electrical signal. The signal measured by sensor will be amplified to input to ECU.
This piezo element type sensor changes pressure into electrical signal. Accordingly, when the shape of diaphragm
changes, electrical resistance in the layers on the diaphragm changes then can measure 0.5 ~ 5 V.
• Sensor input voltage: 5 ± 0.1 V
• Output signal voltage of sensor
- 4.055 ± 0.125 V: 1600 ± 15bar
- 0.5 ± 0.04 V: 0 bar
