Detailed Description

The Gates PV402 vapor canister purge solenoid is engineered to replace a worn or malfunctioning purge valve and restore proper evaporative emission control operation. By regulating vapor flow from the charcoal canister into the engine intake, this component helps the EVAP system operate as intended on compatible Chevrolet Silverado and GMC Sierra models. The PV402 part number is useful for matching the correct replacement during service, and the Gates PV402 designation appears across the listed fitments.

Fitment includes 2004-2007 Chevrolet Silverado 1500, 2004-2007 Chevrolet Silverado 2500 HD, 2004-2006 Chevrolet Silverado 3500, 2004-2007 GMC Sierra 1500, and 2004-2007 GMC Sierra 2500 HD, along with additional Silverado and Sierra variants listed in the application data. This makes the PV402 a practical choice for EVAP repair on work trucks and classic-model applications.

What It Helps Address

• EVAP system fault codes related to purge control.
• Rough idle or drivability issues caused by incorrect vapor purge operation.
• Fuel vapor leakage from a purge valve that no longer seals or cycles properly.
• Emissions test failures tied to evaporative emission control performance.
• Hard starting or inconsistent running after refueling when purge control is compromised.

Installation Notes and Tips

Confirm the connector style, hose port count, and terminal configuration before installation. Match the PV402 part number to the vehicle application and verify the listed Chevrolet Silverado or GMC Sierra fitment in the catalog before service. Inspect related EVAP hoses and electrical connectors during replacement to ensure the system operates correctly after installation.

Quality Assurance

Gates states that this vapor canister purge solenoid is made from high-quality materials for durability and maximum service life. Replacing the purge solenoid helps restore proper EVAP system operation and performance.
