DTC DETECTION CONDITION CHART

DTC No.	Monitoring Item	DTC Detection Condition	Trouble Area	Detection Timing	Detection Logic
P0441	EVAP VSV (Vacuum Switching Valve) stuck open	Vacuum pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure is measured. 0.02 inch leak pressure standard is measured at the start and at the end of leak check. If stabilized pressure is higher than [second 0.02 inch leak pressure standard x 0.2], ECM (Included in HV control ECU) determines that EVAP VSV stuck open	EVAP VSV Connector/wire harness (EVAP VSV - HV control ECU) HV control ECU Pump module Leakage from EVAP system	While ignition switch off	2 trips
P0441	EVAP VSV stuck closed	After EVAP leak check is performed, EVAP VSV turned ON (open), and atmospheric air is introduced into EVAP system. 0.02 inch leak pressure standard is measured at the start and at the end of the check. If pressure does not return to near atmospheric pressure, ECM (Included in HV control ECU) determines that purge valve stuck closed	EVAP VSV Connector/wire harness (EVAP VSV - HV control ECU) HV control ECU Pump module Leakage from EVAP system	While ignition switch off	2 trips
P0441	Purge flow	While engine running, the following conditions are successively met: Negative pressure is not created in EVAP system when EVAP VSV turned ON (open) EVAP system pressure change is less than 0.5 kPa (3.75 mmHg) when vent valve turned ON (closed) Atmospheric pressure change between before and after purge flow monitor is less than 0.1 kPa (0.75 mmHg)	EVAP VSV Connector/wire harness (EVAP VSV - HV control ECU) Leakage from EVAP line (EVAP VSV - Intake manifold) HV control ECU	While engine running	2 trips
