DTCP1238INJECTOR MALFUNCTION
HINT:

For more information on the injector and the common rail system, see page 05±517.

If P1238 is present, use the diagnostic trouble code matrix for fuel sys\
tem, see page 05±517.
CIRCUIT DESCRIPTION
The ECM detects combustion deterioration for specific cylinder.
HINT:

The cylinder that has compensation learned value for INJ VOL varies from other cylinders may be mal-
functioning.

If DTC P0093 (Fuel leaks in high±pressure area) is present simultan\
eously, leakage malfunction of the
cylinder probably be occurred.

If DTC P0200 (Open or short in EDU or injector circuit) is present sim\
ultaneously, there probably be
faulty circuit located between the ECM and the injector including the ED\
U.

If only DTC P1238 (Injector malfunction) is present, probably the injector is \
mechanical malfunction
or insufficient compression (valve clearance, etc) has occurred, not an open o\
r short malfunction of
the ECM, EDU and injector circuit.

Solenoid valve of the injector is the same type of the pressure discharg\
e valve.

when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time o\
f the malfunction.

DTCP0168FUEL TEMPERATURE TOO HIGH
CIRCUIT DESCRIPTION
Refer to DTC P0180 on page 05±599.
DTC No.DTC Detection ConditionTrouble Area
P0168
When THF greater than 35 \fC (95 \fF) and less than 60 \fC
(140 \fF), and THF
±6.7 \fC (20 \fF), and when starting engine,
conditions (a) and (b) continue (1 trip detection logic):
(a)Vehicle speed is changing (Not stable)
(b)THF change is lower than 3 \fC (5.4 \fF) after the engine was
started.

Fuel temperature sensor
In case that reading value of fuel temp. sensor will not change
more than 1 \fC (1.8 \fF) even after repeating 6 trips (detection
logic) of adjusting speed pattern with THF more than 60 \fC
(140 \fF) after the engine was started.
INSPECTION PROCEDURE
HINT:

If DTCs ºP0180, P0182and P0183º are output simultaneously, fuel temperature sensor circuit may be
open or short. Perform the troubleshooting of DTC ºP0180, P0182 or P0183º\
first.

PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Description
(1)When troubleshooting Euro±OBD vehicles, theonly difference from the usual troubleshooting pro-
cedure is that you connect the vehicle to the OBD
scan tool complying with ISO 15031±4 or hand±
held tester, and read off various data output from
the vehicle's ECM.
(2)Euro±OBD regulations require that the vehicle's on±board computer illuminates the Check Engine
Warning Light (Malfunction Indicator Lamp)/CHK
ENG (MIL) on the instrument panel when the com-
puter detects a malfunction in the emission control
system/components or in the driving system com-
ponents which affect vehicle emissions, or a mal-
function in the computer. In addition to CHK ENG
(MIL) illuminating when a malfunction is detected,
the applicable Diagnostic Trouble Codes (DTCs)
prescribed by ISO15031±6 are recorded in the
ECM memory.
If the malfunction does not occur in 3±trip, the CHK ENG (MIL)
goes off but the DTCs remain recorded in the ECM memory. (3)To check the DTCs, connect the OBD scan tool orhand±held tester to the Data Link Connector 3
(DLC3) on the vehicle. The OBD scan tool or hand±
held tester also enables you to erase the DTCs and
check freezed frame data and various forms of en-
gine data (For operating instructions, see the OBD
scan tool's instruction book.).
(4)DTCs include ISO controlled codes and manufac- turer controlled codes. ISO controlled codes must
be set as prescribed by the ISO, while manufacturer
controlled codes can be set freely by the manufac-
turer within the prescribed limits (See DTC chart on
page 05±996).
(5) The diagnosis system operates in normal mode during normal vehicle use. It also has a check mode
for technicians to simulate malfunction symptoms
and troubleshoot. Most DTCs use 2 trip detection
logic (*) to prevent erroneous detection, and ensure
thorough malfunction detection. By switching the
ECM to check mode when troubleshooting, techni-
cians can cause the CHK ENG (MIL) to illuminate
for a malfunction that is only detected once or mo-
mentarily (Hand±held tester only) (See step 2).
