DTC DETECTION LOGIC

NOTE:

If DTC P1451 is displayed with DTC P0452 or P0453, first perform the trouble diagnosis for DTC P0452 or

P0453. Refer to 

EC-380, "DTC Logic"

 or 

EC-383, "DTC Logic"

.

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 

EC-454, "Diagnosis Procedure"

.

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-

tem Pressure Sensor)"

.

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

.

3.

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 

EM-32,

"Exploded View"

.

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 

FL-27, "2WD : Exploded View"

.

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)].
