Dorman 911-387 Vapor Canister Purge Valve

Dorman 911-387 is a direct replacement vapor canister purge valve for the evaporative emissions system on select Toyota Yaris models. Built for a precise fit and plug-and-play installation, it restores proper purge-valve function while meeting emissions-system requirements.

Key Features

• Direct replacement for the original equipment purge valve
• Engineered for a precise fit on the evaporative emissions system
• Plastic housing with an elliptical connector shape
• Two-port design with 0.325 in port outside diameters
• Includes a mounting bracket and mounting hardware
• 2-terminal male electrical connection for OE-style integration

Detailed Description

This Dorman vapor canister purge valve is built to replace the factory unit on 2013-2019 Toyota Yaris applications. The part number 911-387 is designed around OE-style dimensions, including a 2.56 in overall length, 0.25 in thread diameter, and a single mount hole layout for straightforward installation. It also features a 0.21 in inlet inside diameter and a 0.325 in connector hose inside diameter to match the original evaporative emissions plumbing.

As part of the EVAP system, the purge valve controls vapor flow from the charcoal canister into the engine intake. When the original valve no longer seals or responds correctly, drivability and emissions performance can be affected. This replacement is built to restore normal purge-valve operation on Toyota Yaris models and is a practical choice when servicing an emissions fault. This part cross-references Toyota OE-style numbers such as 2586021090 and CP584 for the same application.

What It Helps Fix

• Check engine light related to EVAP purge valve faults
• Fuel vapor leakage from a worn or sticking valve
• Rough idle or drivability issues tied to purge control problems
• Emissions test failures caused by evaporative system malfunction
• Hard starting after refueling when purge operation is inconsistent

Installation Notes and Tips

Fits 2013-2019 Toyota Yaris, N/A. Confirm hose routing, connector style, and mounting location against the original valve before installation. The plug-and-play design supports direct replacement, and the included bracket helps match the factory mounting arrangement. Verify all EVAP connections are fully seated and inspect nearby hoses for cracks or leaks while servicing the valve.

Quality Assurance

Dorman manufactures this purge valve as an OE-style replacement for emissions-system service and compliance-focused repairs. Part number 911-387 is built to meet the fit and function expected for the original application.
