DETECTED
DTC P0301 CYLINDER 1 MISFIRE DETECTED
DTC P0302 CYLINDER 2 MISFIRE DETECTED
DTC P0303 CYLINDER 3 MISFIRE DETECTED
DTC P0304 CYLINDER 4 MISFIRE DETECTED
CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation for each cylinder.
The ECM counts the number of times the engine speed change rate indicates that misfire has occurred. And
when the misfire rate equals to or exceeds the count of indicating that the engine condition has deteriorated,
the CHK ENG is illuminated.
If the misfire rate is high enough and the driving conditions will cause the catalyst to overheat, the CHK ENG
blinks when misfiring occurs.
HINT:

For any particular 200 revolutions of the engine, misfiring which would result in overheating of catalyst
is detected. This cause CHK ENG to blink (1 trip detection logic).

For any particular 1,000 revolutions of engine, misfiring which would result in a deterioration of emis-
sions. This illuminates CHK ENG (2 trip detection logic).

HINT:
After confirming DTC ºP0088 and P1229º, use the hand±held tester to \
confirm the fuel rail pressure from
the ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / COMN RAIL PRESSº.
Engine SpeedFuel Pressure (MPa)
IdlingApprox. 30 to 40
Running the engine at 2,500 rpm (No engine load)Approx. 50 to 100
MONITOR DESCRIPTION
P0088 (Internal fuel pressure too high):
The ECM will set this DTC if the fuel pressure inside the common rail is\
beyond 200 MPa (2,039 kgf/cm
2,
29,007 psi). This DTC indicates that the suction control valve may be stuck o\
pen, or there may be short in
its circuit, and the pressure discharge valve may be stuck close, or the\
re may be open in its circuit.
If this DTC is present, the ECM enters fail±safe mode and limits the \
engine power. The fail±safe mode will
continue until the ignition switch is turned OFF.
P1229 (Fuel over fed):
The ECM will set this DTC if the actual fuel pressure inside the common rai\
l stays higher than the target fuel
pressure, despite the ECM closing the suction control valve. This DTC co\
de represents that the suction con-
trol valve may be stuck open, or there may be short in its circuit. Unde\
r this condition, the pressure discharge
valve will operate quite often.
If this DTC is present, the ECM enters fail±safe mode and limits the en\
gine power. The fail±safe mode will
continue until the ignition switch is turned OFF.
