INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1PERFORM ACTIVE TEST BY HAND±HELD TESTER(VSV FOR EVAP)
(a)Disconnect the vacuum hose from the VSV for EVAP.
(b)Start the engine.
(c)Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / EVAP VSVº (press the right or left button).
(d)When the VSV for EVAP is operated by the hand±held tester, check whether the disconnected hose applies suc-
tion to your finger.

CONFIRMATION ENGINE RACING PATTERN
(a) Connect the hand±held tester to the DLC3, or connect the probe of the oscilloscope between terminals
OX1A, OX2A, OX1B or OX2B and E2 of the ECM connectors.
(b) Start the engine and warm it up with all the accessories switched OFF until the engine coolant tempera-
ture is stable.
(c) Run the engine at 2,500 to 3,000 rpm for about 3 minutes.
(d) After confirming that the waveforms of the heated oxygen sensor (bank 1, 2 sensor 1 (OX1A, OX2A))
which oscillates around 0.5 V during feedback to the ECM, check the waveform of the heated oxygen
sensor (bank 1, 2 sensor 2 (OX1B, OX2B)).
HINT:
If there is a malfunction in the system, the waveform of the
heated oxygen sensor (bank 1, 2 sensor 2 (OX1B, OX2B)) is
almost the same as that of the heated oxygen sensor (bank 1,
2 sensor 1 (OX1A, OX2A)) on the left.
There are some cases where, even though a malfunction ex-
ists, the CHK ENG may either light up or not light up.

7. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as a first step of troubleshooting is one of the meth-
ods to shorten diagnostic time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TESTº

INSPECTION PROCEDURE
HINT:

If DTCs ºP0115, P0116, P0117and P0118º are output simultaneously, engine coolant temperature
sensor circuit may be open or short. Perform the troubleshooting of DTC ºP0\
115, P0117 or P0118º first.

IdlingApprox. 30 to 40
Running the engine at 2,500 rpm (No engine load)Approx. 50 to 100
MONITOR DESCRIPTION
P0093 (Fuel leaks in high±pressure area):
This DTC stands for fuel leaks is existing in high±pressure area in the c\
ommon 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 decreasing rate of the internal fuel press\
ure is large when injecting the fuel.
In the common rail system, high±pressure fuel (approx. 30 to 180 MPa (\
306 to 1,835 kgf/cm
2, 4.351 to
26,106 psi)) is always applied to the high±pressure area including the su\
pply pump, common rail, injector
and piping. The ECM adjusts the suction control valve opening angle to obtain the target internal fuel pres-
sure.
If this DTC is present, the ECM enters fail±safe mode and permits drivi\
ng the vehicle for extra 1 minute before
stopping both the fuel injection and supply pump operation, then stops the engine\
. The fail±safe mode will
continue until the ignition switch is turned OFF.
