DTC Detection Logic

WARNING: This page is about a different variant/trim than selected.

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

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0087	LOW FUEL PRES (High fuel pressure too low)	1	Diagnosis condition	Engine cold start [water temperature 5 deg.C (41 deg.F) - 40 deg.C (104 deg.F)]
			Signal (terminal)	Fuel rail pressure signal
			Threshold	Fuel rail pressure does not reach 1.3 MPa (13 bar, 13.3 kg/cm2, 188.5 psi)
			Diagnosis delay time	--
		2	Diagnosis condition	Engine idle condition after cold start [water temperature 5 deg.C (41 deg.F) - 40 deg.C (104 deg.F)]
			Signal (terminal)	Fuel rail pressure signal
			Threshold	Fuel rail pressure remains at 8.5 MPa (85 bar, 86.7 kg/cm2, 1232.8 psi) or less
			Diagnosis delay time	1 second or more
		3	Diagnosis condition	After engine start (regardless of water temperature)
			Signal (terminal)	Fuel rail pressure signal
			Threshold	Actual fuel pressure - Target fuel pressure ? 2.7 MPa (27 bar, 27.5 kg/cm ² , 392 psi)
			Diagnosis delay time	5 seconds or more
