NOTE:
If DTC P1451 is displayed with DTC P0452 or P0453, first perform the trouble diagnosis for DTC P0452 or
P0453. Refer to
DTC CONFIRMATION PROCEDURE
NOTE:
Never refuel before and during the following procedure.
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and warm it up to normal operating temperature
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start the engine. Wait at least for 15 seconds after the start of idle running.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000012198006
1.
CHECK HOSE AND PIPING
1. Turn ignition switch OFF.
2. Check the following.
-
Blockage, crush, or damage in the hose and the piping of EVAP purge line between fuel tank and intake
manifold.
-
Blockage, crush, or damage in the hose and the piping of intake air passage between inlet air duct and
intake manifold.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts
2.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
Check EVAP control system pressure sensor. Refer to
EC-455, "Component Inspection (EVAP Control Sys-
Is the inspection result normal?
DTC No.
Trouble diagnosis
(Trouble diagnosis content)
DTC detecting condition
Possible cause
P1451
TC/SC PRES-EVAP PRES
(EVAP control system pressure
sensor/turbocharger boost sen-
sor correlation)
ECM detects a state that the pressure differ-
ence remains
−13.0 kPa (−98 mmHg, −3.83
inHg) or less/13.5 kPa (102 mmHg, 3.99 in-
Hg) or more for continuously for 5 seconds or
more under the condition that the pressure of
the EVAP control system pressure sensor
and that of the turbocharger boost sensor are
equal.
• EVAP control system pressure sensor
• Turbocharger boost sensor
• Clogging, crushing, or damage in
hose or piping

CHECK TURBOCHARGER BOOST SENSOR
Check turbocharger boost sensor. Refer to
EC-455, "Component Inspection (Turbocharger Boost Sensor)"
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Replace turbocharger boost sensor (with intake temperature sensor 2). Refer to
Component Inspection (EVAP Control System Pressure Sensor)
INFOID:0000000012198007
1.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
1. Turn ignition switch OFF.
2. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.
Always replace O-ring with a new one.
3. Install a vacuum pump to EVAP control system pressure sensor.
4. Turn ignition switch ON and check output voltage between ECM harness connector and ground under the
following conditions.
CAUTION:
• Always calibrate the vacuum pump gauge when using it.
• Do not apply below -93.3 kPa (-0.952 kg/cm
2
, -13.53 psi) or pressure over 101.3 kPa (1.033 kg/
cm
2
, 14.69 psi).
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace EVAP control system pressure sensor. Refer to
Component Inspection (Turbocharger Boost Sensor)
INFOID:0000000012198008
1.
CHECK TURBOCHARGER BOOST SENSOR
1. Turn ignition switch OFF.
2. Remove turbocharger boost sensor with its harness connector.
3. Install pressure pump (A) to turbocharger boost sensor (1).
CAUTION:
When insert a pressure pump hose to the sensor, be careful
to the damage of the sensor housing.
4. Turn ignition switch ON.
5. Check the voltage between ECM harness connector terminals
as per the following conditions.
NOTE:
• Always calibrate the pressure pump gauge when using it.
• Inspection should be done at room temperature [10 - 30
°C (50 - 86°F)].
