DTC SUMMARY

DTCs	Monitoring Items	Malfunction Detection Conditions	Trouble Areas	Detection Timings	Detection Logic
P2419	Vent valve stuck closed	P043E, P043F, P2401, P2402 and P2419 present when one of following conditions met during key-off EVAP monitor: EVAP pressure just after reference pressure measurement greater than -1 kPa-g (-7.5 mmHg-g) Reference pressure less than -4.85 kPa-g (-36.4 mmHg-g) Reference pressure greater than -1.057 kPa-g (-7.93 mmHg-g) Reference pressure not saturated Reference pressure difference between first and second 0.7 kPa-g (5.25 mmHg-g) or more HINT: Typical example values	Canister pump module (Reference orifice, leak detection pump, vent valve) Connector/wire harness (Canister pump module - ECM) EVAP system hose (pipe from air inlet port to canister pump module, canister filter, fuel tank vent hose) ECM	While ignition switch OFF	2 trip
P2420	Vent valve stuck open (vent)	Following condition met during key-off EVAP monitor: EVAP pressure change when vent valve closed (ON) less than 0.3 kPa-g (2.25 mmHg-g)	Canister pump module (Reference orifice, leak detection pump, vent valve) Connector/wire harness (Canister pump module - ECM) ECM	While ignition switch OFF	2 trip

HINT:

The vent valve is built into the canister pump module.
