P2407 OBD-II: Evaporative Emission System Leak Detection Pump Sense Circuit
P2407 Severity
Will P2407 go away on its own?
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.
What causes OBD-II fault code P2407?
The Evaporative Emission System (EVAP) vents fuel vapors from the tank to the intake manifold so the vapors are burned through the engine's normal combustion process. The EVAP system uses a leak detection pump sensor to monitor the pressure/vacuum in the EVAP system. If the sensor sends back an implausible signal, code P2407 will be set.
