P2419 Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
The Leak Detection Pump is part of the Evaporative Emissions System. After the vehicle has been sitting for a few hours, this pump will turn on and create a vacuum in the EVAP system. The engine computer (PCM) runs this test when the vehicle is off. If the PCM does not see the Leak Detection Pump activate as requested, or does not see a vacuum created in the EVAP System, the PCM will set code P2419.
