Fault text
Rail pressure sensor, plausibility: Signal frozen

Fault description
The diagnostic function monitors the variations in the signal
from the rail-pressure sensor.

Condition for fault identification
Test condition:
The fault is recognized when the voltage of the rail-pressure
sensor varies by less than 5 mV.
Potential problem source(s):
- Defect in wiring harness between DME and rail-pressure
sensor
- Defective rail-pressure sensor
- Defective DME
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine on
- Rail pressure exceeds 4 MPa

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check wiring harness between DME and rail-pressure
sensor
- Replace rail-pressure sensor
- Replace DME
