DTC P1282:00 [SKYACTIV-D 1.5]

id0102q2214200

DTC P1282:00

Common rail control system problem
DETECTION CONDITION
•  When the following conditions are met, the common rail fuel pressure value exceeds 250 MPa {2,549 kgf/cm2, 36,260 psi} or the fuel pressure value exceeds the value calculated by the PCM based on the engine speed for a continuous 1 s.
MONITORING CONDITIONS
―  Battery voltage: 8 V or more
―  0.5 s have elapsed after the ignition was switched ON (engine on)
―  Engine speed: above 500 rpm
―  The following DTCs are not detected:
•  Fuel pressure sensor: P0191:00, P0192:00, P0193:00
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Limits the engine torque or the upper limit of the engine speed.
POSSIBLE CAUSE
•  Fuel pressure relief valve malfunction
•  Fuel pressure sensor malfunction
•  Suction control valve malfunction
•  Fuel pipe perforation or breakage (poor contact)
•  Fuel filter clogged (The PCM corrects the fuel pressure in the direction of increase via feedback control in response to a fuel pressure decrease due to temporary clogging. If the clogging is cleared, a DTC is detected because fuel pressure increases to the threshold or more.)
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the FREEZE FRAME DATA/snapshot data on the repair order.

Go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Are any other PENDING CODEs and/or DTCs present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
(See DTC TABLE [SKYACTIV-D 1.5].)
No
Go to the next step.
4
INSPECT FUEL PRESSURE RELIEF VALVE
•  Inspect the fuel pressure relief valve.
•  Is there any malfunction?
Yes
Replace the common rail, then go to Step 9.
(See COMMON RAIL REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
No
Go to the next step.
5
INSPECT FUEL PRESSURE SENSOR
•  Inspect the fuel pressure sensor.
•  Is there any malfunction?
Yes
Replace the common rail, then go to Step 9.
(See COMMON RAIL REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
No
Go to the next step.
6
INSPECT SUCTION CONTROL VALVE
•  Inspect the suction control valve.
•  Is there any malfunction?
Yes
Replace the suction control valve, then go to Step 9.
(See SUCTION CONTROL VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
No
Go to the next step.
7
INSPECT FUEL PIPE
•  Inspect the fuel pipe installation condition.
•  Is there any malfunction?
Yes
Install the fuel pipe properly, then go to Step 9.
No
Go to the next step.
8
INSPECT FUEL FILTER
•  Inspect the fuel filter for clogging.
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
(See FUEL FILTER REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
No
Go to the next step.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
Caution
•  While performing this step, always operate the vehicle in a safe and lawful manner.
•  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
•  Drive the vehicle under the FREEZE FRAME DATA/snapshot data condition.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 1.5].)
No
DTC troubleshooting completed.
