P0450 2007 Scion xB Code - Evaporative Emission Control System Pressure Sensor/Switch
Quick Answer
The Evaporative Emission System (EVAP) vapor pressure sensor, VSV for canister closed valve (CCV) and VSV for pressure switching valve are used to detect abnormalities in the evaporative emission control system. Common causes include Faulty Evaporative Emission System (EVAP) Vapor Pressure Sensor, Evaporative Emission System (EVAP) Vapor Pressure Sensor harness is open or shorted, Evaporative Emission System (EVAP) Vapor pressure sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
