P0450 2006 Toyota Camry Description
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. The Engine Control Module (ECM
) decides whether there is an abnormality in the evaporative emission control system based on the vapor pressure sensor signal.
