DTC Description

DTC DETECTION LOGIC 

NOTE: DTC P0087 may be displayed when running out of gas.

POSSIBLE CAUSE 

• Fuel system
• Leakage in fuel line
• High pressure fuel pump
• Low pressure fuel pump
• Damage in lifter
• Out of gas
• Harness or connector
• Fuel Pressure sensor
• Fuel Injector stuck open
• Clogged in fuel line
• High Pressure fuel pump cam and lifter

FAIL-SAFE 

NOTE: Any of the following fail-safe is applied.

Engine operating condition in fail-safe mode
Fail safe mode		Vehicle behavior
Traveling control mode	Accelerator angle variation control	ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction. NOTE: ECM does not control the accelerator pedal releasing speed.
Device fix mode		This mode fixes the EVT control solenoid valve in the reference position. The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
Combustion control mode	Stratified charge combustion control at starting	No stratified charge combustion at starting (cold start).
