Detailed Product Overview

This vapor canister purge valve is used to control fuel vapor flow from the charcoal canister into the engine intake as part of the evaporative emissions system. Dorman 911-393 follows the OE-style layout with a 3.6 in body length, 0.25 in thread diameter, and two mounting holes sized at 0.33 in, helping it align with the factory location on Subaru Impreza, Forester, Legacy, and Outback models.

This part cross-references Standard Ignition CP607 for the same application.

Common Repair Symptoms

• Check engine light related to EVAP system faults
• Fuel vapor leakage from a worn or sticking purge valve
• Rough idle or drivability issues caused by improper purge control
• Failed emissions inspection tied to evaporative system codes
• Hard starting after refueling from purge valve malfunction

Installation Notes

Verify connector style, port size, and mounting points before installation. The valve uses a single elliptical connector, 2 male terminals, and a bracketed mount, so it should be matched to the original routing and electrical connection on the vehicle. Confirm the EVAP hoses are in good condition during replacement to avoid repeat faults.

Quality Assurance

Dorman designs this purge valve as a direct-fit replacement for the original equipment part and builds it to support evaporative emissions compliance requirements.
