Detailed Product Information

The Dorman 911-409 purge valve is engineered to replace the factory valve used in the evaporative emissions control system. It helps regulate vapor flow from the charcoal canister to the engine intake, supporting proper emissions-system operation on 2012-2016 Chevrolet Cruze, 2016 Chevrolet Cruze Limited, 2013-2020 Chevrolet Sonic, 2013-2021 Chevrolet Trax, and 2013-2021 Buick Encore applications. This part cross-references Standard Ignition (e.g., CP781, CP870) for the same application.

Key dimensions include a 10.4-inch length, a 0.236-inch connector hose inside diameter, a 0.197-inch inlet inside diameter, and port outside diameters of 0.311 inch and 0.315 inch. The valve uses a plastic housing, one rectangular female connector, and two male blade terminals. Dorman 911-409 is a practical OE replacement choice when the original purge valve is no longer sealing or responding correctly.
