Gates PV421 Vapor Canister Purge Solenoid

Vapor Canister Purge Solenoid Overview

The Gates PV421 vapor canister purge solenoid restores evaporative emission control function when the original valve no longer regulates purge flow correctly. It is built with durable materials for service life and direct replacement fitment across a wide range of Ford, Lincoln, Mazda, and Mercury applications.

• Direct replacement vapor canister purge solenoid for EVAP system service
• Two hose ports, one female connector, and blade terminals for straightforward electrical and vacuum connection
• Rectangle connector design with a compact 13 mm outside diameter
• Fits Ford Edge, Ford Fusion, Lincoln MKX, Lincoln MKZ, Mazda CX-9, Mazda 6, Mercury Milan, and Lincoln Zephyr applications
• Gates PV421 is built for restoring proper purge solenoid operation and emissions control performance

Detailed Fitment and Function

The PV421 is a vapor canister purge solenoid used in the evaporative emission control system to manage fuel vapor routing from the charcoal canister. When the valve sticks, leaks, or fails electrically, the system can lose purge control and trigger drivability or emissions concerns. This part cross-references Dorman - OE Solutions 911-111 and Standard Ignition CVS83 for the same application. For buyers searching for a Ford Fusion vapor canister purge solenoid, a Mazda CX-9 purge solenoid, or a Lincoln MKZ EVAP purge valve, Gates PV421 is the matching service part.

Common Issues This Part Can Address

• Check engine light related to EVAP purge circuit faults
• Fuel vapor flow problems caused by a sticking purge valve
• Rough idle or hard starting linked to purge control issues
• Emissions test failures caused by improper evaporative system operation
• Loss of proper purge function in Ford, Lincoln, Mazda, and Mercury vehicles

Installation Notes and Tips

Verify connector shape, terminal count, hose port count, and outside diameter before installation. Confirm the vehicle application against the fitment list for the exact year and model, including Ford Edge, Ford Fusion, Lincoln MKX, Lincoln MKZ, Mazda CX-9, Mazda 6, Mercury Milan, and Lincoln Zephyr. Inspect vacuum hoses and electrical connectors for wear or contamination before installing the new solenoid.

Quality Assurance

Gates manufactures the PV421 with high-quality materials to support durability and long service life. Replacing a worn purge solenoid helps return the evaporative emission control system to proper operation.
