DTC P2419: General Description
The fuel vapor containment valve is installed between the fuel tank and the purge passage to be used to isolate the fuel tank from the purge passage except when refueling to create a sealed condition. The fuel vapor containment valve is normally closed. The powertrain control module (PCM) detects a malfunction and stores a DTC when open signal is returned continuously for the prescribed number of times though open signal is not output to the fuel vapor containment valve.
