On-Board Refueling Vapor Recovery (ORVR) System

WARNING: This page is about a different variant/trim than selected.

The On-Board Refueling Vapor Recovery (ORVR) System is an on-board vehicle system designed to recover fuel vapors during the vehicle refueling operation. The flow of liquid fuel down the fuel filler pipe provides a liquid seal which prevents vapor from leaving the fuel filler pipe. An evaporative emission (EVAP) pipe transports the fuel vapor to the EVAP canister for use by the engine.
