DTC P144C:00 (PCM, VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

DESCRIPTION	Evaporator system: Abnormal purge flow (during boost)
	Determination conditions	Following conditions are met from when the CV solenoid valve closes: Pressure difference detected by fuel tank pressure sensor is less than 100 Pa {10.2 kgf/m² , 0.0145 psi} Purge flow amount is 0.6 L/min or more
DETECTION CONDITION	Preconditions	Purge flow amount: 3.6 l/min or more IAT: 4.44-43.33 °C {40.0-109.9 °F}^1 Barometric pressure: 72.23 Pa {7.365 kgf/m² , 0.01048 psi} or more^1 Period ignition is switched off before engine is started: 210 min or more Fuel level in fuel tank: 15-85%^1 Engine boost condition: During boost Battery voltage: above 8 V^1 The following DTCs are not detected: ECT sensor: P0116:00, P0117:00, P0118:00 Fuel tank pressure sensor: P0451:00, P0452:00, P0453:00 Purge solenoid valve: P0443:00 CV solenoid valve: P0446:00 IAT sensor No. 1: P0112:00, P0113:00 BARO sensor: P2227:00, P2228:00, P2229:00 Fuel gauge sender unit: P0460:00, P0461:00, P0462:00, P0463:00 ^*1 : Standard can be verified by displaying PIDs using M-MDS
	Malfunction determination period	5 s period
	Drive cycle	2
	Self test type	CMDTC self test
	Sensor used	Fuel tank pressure sensor
FAIL-SAFE FUNCTION	Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT	Illuminates check engine light.
POSSIBLE CAUSE	Malfunction in evaporative gas passage between purge solenoid valve and ejector Clogging, cracks, and poor connection of hose between purge solenoid valve and check valve (ejector side) Clogging, cracks, and poor connection of hose between check valve (ejector side) and ejector Check valve (ejector side) malfunction Ejector loose Ejector malfunction Check valve (intake manifold side) malfunction (stuck open) Malfunction in evaporative gas passage between fuel tank and purge solenoid valve Clogging, cracks, and poor connection of hose between fuel tank and fuel tank pressure sensor Clogging, cracks, and poor connection of hose between fuel tank pressure sensor and charcoal canister Clogging, cracks, and poor connection of hose between charcoal canister and purge solenoid valve CV solenoid valve malfunction (stuck open) Charcoal canister malfunction (worsening of airflow resistance, or other) Purge solenoid valve malfunction PCM malfunction
