P0468 OBD-II: EVAP Purge Flow Sensor Circuit High
P0468 Severity
Will P0468 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 P0468?
The evaporative control (EVAP) system captures any fuel vapors from the fuel tank and sends them through the vehicle's intake to be burned in the normal combustion process. The EVAP Purge Valve allows the fuel vapors to enter the engine through the intake. When the engine control module (PCM) detects the evap system has flow when it should not, it will set code P0468.
