P2419 Meaning
5 hours after ignition is turned off, the leak detection pump creates negative pressure (vacuum) in the EVAP system. The Engine Control Module (ECM) monitors leaks and actuator malfunctions based on EVAP pressure. TIP: If engine coolant temperature is not below 35°C (95°F) 5 hours after turning off ignition, monitor check starts 2 hours later. If still not below 35°C (95°F) 7 hours after ignition is turned off, monitor check starts 2.5 hours later.
