DTC DETECTION LOGIC

NOTE:

• If DTC P0087 is displayed with DTC P0090 and/or P1197, first perform the trouble diagnosis for DTC

P0090 and/or P1197.

• DTC P0087 may be displayed when running out of gas or air accumulation.

DTC CONFIRMATION PROCEDURE

1.

CHECK FUEL LEAKAGE

1. Turn ignition switch ON.

2. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.

3. Start the engine.

4. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.
Is inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

• Before performing the following procedure, check that the fuel tank is 1/8 full of fuel.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE-1

WITH CONSULT

Diagnosis Procedure

INFOID:0000000012197774

1.

PERFORM THE HIGH PRESSURE FUEL PUMP COMPONENT INSPECTION

Perform the high pressure fuel pump component inspection. Refer to 

EC-218, "Component Inspection (High

Pressure Fuel Pump)"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace high pressure fuel pump. 

EM-49, "Removal and Installation"

.

2.

CHECK FUEL LEAKAGE

1. Start the engine.

2. Visually check that the fuel pump, fuel rail, and fuel piping have no fuel leakage.
Is the inspection result normal?

YES

>> Check that the fuel system has no breakage, bend, and crush. Refer to 

FL-5, "Inspection"

.

NO

>> Repair or Replace the error-detected parts.

Component Inspection (High Pressure Fuel Pump)

INFOID:0000000012197775
