Detailed Description

This purge valve regulates when stored fuel vapors are drawn from the charcoal canister into the intake stream for combustion. On the listed Honda Civic, Honda CR-V, Honda Accord, and Acura Integra applications, a properly functioning purge valve helps maintain evaporative system operation and supports emissions compliance. Standard Ignition CP821 is built around the connector, terminal, and port configuration used on these vehicles, making it a practical replacement when the original valve is no longer operating correctly.

This part cross-references 2-284056 and PV2004 for the same application. The CP821 part number is also referenced alongside CP910 in Standard Ignition catalog listings.

Common Issues This Part May Address

• Check engine light related to EVAP purge flow faults

Installation Notes and Tips

Verify connector shape, terminal style, and port count against the original valve before installation. Inspect EVAP hoses and electrical connectors for damage, carbon buildup, or looseness while servicing the purge valve. Confirm the vehicle application by year, make, and model before ordering, especially on Honda Accord and Honda Civic fitments that span multiple model years.

Quality Assurance
