INSPECTION PROCEDURE
HINT:
SIf no trouble is found in troubleshooting of DTC P0335 troubleshoot the engine mechanical system.
SRead freeze frame data usingthe hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
SRead value of hand−held tester
(a) Connect the hand−held tester to the DLC3.
(b) Start the engine and turn the hand−held tester ON.
(c) Select the item: DIAGNOSIS / OBD/MOBD / DATA LIST / ALL / ENGINE SPD.
The engine speed can be observed in DATA LIST using the hand−held tester. If there is no NE signals from
the crankshaft position sensor despite the engine revolving, the engine speed will be indicated as zero. If
voltage output from the crankshaft position sensor is insufficient, the engine speed will be indicated as lower
PRM (than the actual RPM).

CONFIRMATION DRIVING PATTERN
(a) Connect the hand −held tester to the DLC3.
(b) Record DTCs and freeze frame data.
(c) Switch the hand −held tester from normal mode to check mode (see page 05 −20).
(d) Read the value on the misfire counter for each cylinder when idling. If the value is displayed on the misfire counter, skip the following procedure of confirmation driving.
(e) Drive the vehicle several times with the engine speed, load and its surrounding range shown with EN-
GINE SPD, CALC LOAD in the freeze frame data or MISFIRE RPM, MISFIRE LOAD in the DATA LIST.
If you have no hand −held tester, turn the ignition switch to OFF after the symptom is simulated once. Then
repeat the simulation process again.
HINT:
In order to memorize the misfire DTC, it is necessary to drive with MISFIRE RPM, MISFIRE LOAD in the
DATA LIST for the period of time in the chart below. Take care not to turn the ignition switch to OFF. Turning
the ignition switch to OFF switches the diagnosis system from check mode to normal mode and all DTCs,
freeze frame data and other data are erased.

Idling3 minutes and 30 seconds or more

2,000 rpm1 minutes and 30 seconds or more
3,000 rpm1minute or more
(f) Check if there is misfire and DTC and the freeze frame data. Record the DTCs, freeze frame data and
misfire counter data.
(g) Turn the ignition switch to OFF and wait at least for 5 seconds.
INSPECTION PROCEDURE
HINT:
SIf DTCs besides misfire DTCs are memorized simultaneously, troubleshoot the non −misfire DTCs first.
SRead freeze frame data using the hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
SIf the misfire does not occur when the vehicle is brought to the workshop, the misfire can be confirmed
by reproducing the condition of the freeze frame data. Also, after finishing the repair, confirm that there
is no misfire (see confirmation driving pattern).
When only a general misfire fault code like P0300 is stored:
SErase the general misfire fault code from the hand −held tester.
SStart the engine and drive the confirmation patten.
SRead the value of the misfire ratio for each cylinder. Or read the DTC.
SPerform repairs on the cylinder that has a high misfire ratio. Or repair the cylinder indicated by the DTC.
SAfter finishing repairs, drive the confirmation pattern again and confirm that no misfire occurs.
SWhen any one of SHORT FT # 1, LONG FT # 1, SHORT FT #2 and LONG FT #2 in the freeze frame
data is over the range of ±20 %, there is a possibility that the air −fuel ratio is becoming RICH ( −20 %
or less) or LEAN (+20 % or more).
SWhen COOLANT TEMP in the freeze frame data is less than 80 ˚C( 176 ˚F), there is a possibility of
misfire only during engine warm −up.
SIf the misfire cannot be reproduced, the following reasons may apply: 1) the vehicle has low fuel, 2)
improper fuel is being used, and 3) the ignition plug is contaminated.
SBe sure to check the value on the misfire counter after the repair.

DTC P0093 FUEL SYSTEM LEAK DETECTED − LARGE
LEAK
HINT:
S If DTC P 1229 is detected, P0093 (fuel leaks in high −pressurized area) may be detected simultaneous-
ly. Because of the extremely high internal fuel pressure in the common rail opens the pressure limiter,
and the ECM may interpret this as a fault and set P0093.
S For more information on the common rail system, see page 05 −255.
S If P0093 is present, refer to the diagnostic trouble codes (DTCs) table for the fuel system on page
05 −255.

HINT:
After confirming DTC P0093, check the internal fuel pressure of the common rail in the ”DIAGNOSIS / OBD/
MOBD / DATA LIST / ALL / COMN RAIL” using the hand −held tester.
Reference:
Engine SpeedFuel Pressure (MPa)
IdlingApproximately 30 to 40
2,500 rpm (No engine load)Approximately 50 to 100
MONITOR DESCRIPTION
P0093 (Fuel leaks in high −pressurized area):
This DTC stands for fuel leaks that are existing in high −pressurized area in the common rail system. The
ECM constantly monitors the internal fuel pressure of the common rail after the engine is started, and the
ECM then will set this DTC if the drop of the internal fuel pressure is large when injecting the fuel.
In the common rail system, high −pressurized fuel, approximately 30 to 180 MPa (306 to 1,835 kgf/cm
2, 4,35 1
to 26, 106 psi), is always applied to the high −pressurized area including the supply pump, common rail, injec-
tor and piping. The ECM adjusts the suction control valve control current (by applying duty ratio signal) to
obtain the target internal fuel pressure.
If this DTC is present, the ECM enters the fail −safe mode. The fail −safe mode suspends both fuel injection
and supply pump operation, and then stops the engine. Before stopping the engine, the ECM permits driving
the vehicle for 1minute. The fail −safe mode continues until the ignition switch is turned to OFF.
