DTC P1329:00 [PCM (SKYACTIV-D 2.2)]
id0102j5149200
|
DTC P1329:00 |
Common rail pressure higher than desired (engine running) |
|---|---|
|
DETECTION CONDITION
|
• With the following conditions met, the fuel pressure value in the common rail exceeds 250 MPa or exceeds the fuel pressure value calculated by the PCM based on the engine speed for a continuous 1 s.
• With the following conditions met, the fuel pressure value in the common rail exceeds 217 MPa or exceeds the fuel pressure value calculated by the PCM based on the engine speed for a continuous 60 s.
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 fuel pressure. (High pressure)
• Limits the engine torque/limits the maximum engine speed.
• Inhibits the automatic diesel particulate filter regeneration control.
• Inhibits the manual diesel particulate filter regeneration control.
• Inhibits engine-stop by i-stop control.
• Inhibits the EGR control.
|
|
POSSIBLE CAUSE
|
• Fuel filter clogging
• Fuel pressure relief valve malfunction
• Fuel pressure sensor (integrated with fuel injector No.2) connector or terminal malfunction
• Fuel pressure sensor (integrated with fuel injector No.3) connector or terminal malfunction
• Suction control valve malfunction
• Fuel pipe crushing or breakage (poor contact)
• Supply pump malfunction
• PCM malfunction
