P0401-00: (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	EGR flow insufficient detected
Detection condition	Determination conditions	The EGR volume is lower than the specification for the target value for a continuous specified time.
	Preconditions	2 s has passed since the following conditions are met: Intake air temperature: -3.0°C {37°F} or more ^1 Engine coolant temperature: 65.0°C {149°F} or more ^1 Engine speed: 1, 400-2, 600 rpm ^1 Fuel injection control: during fuel cut The following DTCs are not detected: Intake valve timing control system: P0010:00, P0011:00 and P0012:00 CKP sensor and intake CMP sensor: P0016:00 TP sensor: P0122:00, P0123:00 and P2135:00 ECT sensor No. 1: P0116:00, P0117:00 and P0118:00 MAP sensor: P0107:00 and P0108:00 EGR valve control system: P0403:00 MAF sensor: P0100:00 and U060F:00 Exhaust gas pressure sensor: P0472:00 and P0473:00 Boost pressure sensor: P0237:00 and P0238:00 HO2S: P013A:00 Intake manifold is normal Difference between target valve timing and actual valve timing of electric variable valve timing: 3° or less Purge control: not active Charging efficiency: above 0.26 ^1 : Standard can be verified by displaying PIDs using M-MDS
	Drive cycle	2
	Self test type	CMDTC self test
