DTC P0087:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

Description	Fuel pressure sensor circuit range/performance problem
Detection condition	Determination conditions	If any of the following conditions is met under condition A or condition B: Condition A: The actual fuel pressure is lower than the target fuel pressure by 1.2 MPa {12 kgf/cm² , 174 psi} or more even though the fuel pressure feedback amount is maintained high. Condition B: The PCM detects that the actual fuel pressure is 1.7 MPa {17 kgf/cm² , 247 psi} or less continuously or intermittently.
	Preconditions	Engine speed: 500 rpm or more^1 The following DTCs are not detected: Fuel pressure sensor: P0089:00, P0192:00 and P0193:00 High pressure fuel pump: P0091:00 and P0092:00 ^1 : Standard can be verified by displaying PIDs using M-MDS
	Malfunction determination period	Condition A: 5 s period Condition B: Specified time
	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	Not applicable
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 delivery system malfunction (insufficient fuel pressure) Fuel injector malfunction High pressure fuel pump malfunction Relief valve (built-into high pressure fuel pump) malfunction
