P0087-00 (PCM (PYUL)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Fuel pressure sensor system: Circuit malfunction
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 the standard or more lower than the target fuel pressure while the fuel pressure feedback amount is maintained high. Condition B: The PCM detects that the actual fuel pressure is standard 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	Limits intake air amount Stops high pressure fuel pump control Inhibits engine-stop by i-stop 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 terminal malfunction Fuel pressure sensor connector or terminal malfunction PCM connector or terminal 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 PCM malfunction
