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.

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
NO
>> Repair or Replace the error-detected parts.
Component Inspection (High Pressure Fuel Pump)
INFOID:0000000012197775
