Details On DTCs

DESCRIPTION	Fuel pressure sensor circuit range/performance problem
DETECTION CONDITION	Determination conditions	The actual fuel pressure is 1.2 MPa {12 kgf/cm ² , 174 psi} or more lower than the target fuel pressure even through the PCM maintains the fuel pressure feedback amount at high.
	Preconditions	Engine speed: 500 rpm or more ^1 The following DTCs are not detected: Fuel pressure sensor: P0089:00, P0192:00, P0193:00 High pressure fuel pump: P0091:00, P0092:00 ^1 : Value can be verified by displaying PIDs using M-MDS
	Malfunction determination period	5 s period
	Drive cycle	1
	Self test type	CMDTC self test
	Sensor used	Fuel pressure sensor
FAIL-SAFE FUNCTION	Limits intake air amount Stops high pressure fuel pump control
VEHICLE STATUS WHEN DTCs ARE OUTPUT	Illuminates check engine light.
POSSIBLE CAUSE	Air suction in fuel line due to fuel is runout High pressure fuel pump connector or terminals malfunction Fuel pressure sensor connector or terminals malfunction PCM connector or terminals malfunction Fuel pressure sensor malfunction Fuel system malfunction (fuel pressure malfunction) Fuel injector malfunction High pressure fuel pump malfunction Relief valve (built-into high pressure fuel pump) malfunction PCM malfunction
