Fuel injector (2 pin type)

DTC P1329:00

Common rail pressure higher than desired (engine running)
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)
•  When the following conditions are met, the common rail fuel pressure value exceeds 217 MPa {2,213 kgf/cm2, 31,473 psi} or the fuel pressure value exceeds the value calculated by the PCM based on the engine speed for a continuous 60 s.
MONITORING CONDITIONS
―  Battery voltage: 8 V or more
―  0.5 s have elapsed after the ignition was switched ON (engine on)
Diagnostic support note
•  This is an intermittent monitor (fuel system).
•  The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  PCM restricts engine torque.
•  Increase the idle speed.
•  Inhibits the auto diesel particulate filter regeneration control.
•  Inhibits the compulsory diesel particulate filter regeneration control.
•  Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE
•  Fuel pressure relief valve malfunction
•  Fuel pressure sensor malfunction
•  Suction control valve malfunction
•  Fuel pipe perforation or breakage (improper connection)
•  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
