Code P2420 2011 Toyota Camry Description

When 5 hours have elapsed after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in Evaporative Emission (EVAP) system. Then Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on EVAP pressure. The ECM illuminates the MIL and sets a Diagnostic Trouble Code (DTC) if the difference in EVAP pressure in EVAP system pressure is small and does not increase more than 2.25 mmHg (0.3 kPa) within 10 seconds of changing the vent valve from OFF (vent) to ON (closed), the ECM determines that the vent valve is stuck OFF (vent).
