Fault text
Rail-pressure sensor, voltage test: lower threshold undershot

Fault description
The diagnostic function monitors the voltage of the rail-
pressure sensor.

Condition for fault identification
Test condition:
The fault is recognized when the voltage of the rail-pressure
sensor is between 0.2 V and 0.52 V.
Potential problem source(s):
- Defect in wiring harness between DME and rail-pressure
sensor
- Defective rail-pressure sensor
- Defect in high-pressure system
- Defective DME
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- DME not in shutdown phase

Condition for fault memory entry
The diagnostic fault code is logged when the fault remains
present for longer than 1 min.

Action in service
- Check wiring harness between DME and rail-pressure
sensor
- Replace rail-pressure sensor
- Repair problem in high-pressure fuel system
- Replace DME
