P0254: Common Rail Pressure Defect (warning lamp flashes: 23)
P0335: Engine Revolution SNSR (warning lamp flashes: 15)
Generation condition
Diagnosis code is generated under either of the following conditions.
(1) Common rail pressure sensor voltage remains 4.4 V or more for 10 seconds
when common rail pressure is controlled without feedback value.
(2) When above problem (1) is not occurred, common rail pressure sensor volt-
age remains 2.96 V or more for 10 seconds when common rail pressure is
controlled without feedback value.
(3) Common rail pressure sensor voltage remains 4.4 V or more for 5 seconds.
(4) The difference between target common rail pressure and actual common rail
pressure is 30% or more, and MPROP (rail pressure control valve) discharge
rate remains above the specified value for 10 seconds.
Recoverability
System recovers (power is re-supplied to electronic control unit) if signal becomes
normal when starter switch is turned OFF (2 minutes or more)
→
ON.
Control effected by electronic control unit
•
In the case of above problems (1) and (2)
•
Engine warning lamp (red) display
•
Engine is stopped.
•
In the case of above problems (3) and (4)
•
Engine warning lamp (orange) display
•
Injection quantity is limited. (Output is reduced, and exhaust emissions
worsen.)
•
Exhaust gas recirculation control is stopped.
•
Auto cruise control is stopped.
Inspection
Service data
C0: Difference Common Rail Pressure
Other
Supply pump (Have work performed by Bosch.)
Generation condition
Diagnosis code is generated under either of the following conditions.
(1) Signals from engine speed sensor are not input while signals from cylinder
recognition sensor are recognized.
(2) Engine speed recognized by engine speed sensor is higher than 6000 rpm
when engine speed is higher than 450 rpm.
Recoverability
•
In the case of above problem (1)
•
System recovers if signals from engine speed sensor are input while sig-
nals from cylinder recognition sensor are recognized.
•
In the case of above problem (2)
•
System recovers if engine speed recognized by engine speed sensor is
6000 rpm or less when engine speed is higher than 450 rpm.
Control effected by electronic control unit
•
Control is effected using cylinder recognition sensor.
(Output decreases owing to reduced control accuracy.)
•
Auto cruise control is stopped.
