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

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

The vent valve is built into the canister pump module. DESCRIPTION

The description can be found in the EVAP (Evaporative Emission) System (see page ES-335).
