Standard Motor Products CVS6 Vapor Canister Vent Solenoid 2-Terminal — Made in USA, OEM Fit for EVAP Systems

The Standard Motor Products CVS6 is a 2-terminal vapor canister vent solenoid designed to control evaporative emissions valve opening and closing for accurate EVAP system operation.

This compact, two-terminal vent solenoid from Standard Motor Products replaces the factory EVAP vent valve and helps restore correct purge-canister venting. Built in the United States, the CVS6 is a direct-fit replacement part manufactured to meet original equipment form and function. The unit’s small footprint and standardized electrical interface make it an easy swap for technicians and knowledgeable DIYers working on vehicles that use a two-terminal vent solenoid in their evaporative emissions control system.

What does the CVS6 vent solenoid actually do in the EVAP system?

The CVS6 opens and closes the canister vent to regulate when fresh air enters the charcoal canister, allowing the purge system to route fuel vapors to the engine for combustion. It works as an electrically actuated valve: energized to change state and de-energized to return to rest, ensuring the EVAP system only vents at the correct times.

• Controls airflow into the charcoal canister during purge cycles.
• Prevents uncontrolled vapor release when the vehicle is off.
• Interfaces with vehicle PCM via a two-terminal electrical connector.

How do I know if I need to replace my vapor canister vent solenoid?

Typical signs include diagnostic trouble codes related to EVAP vent control, failed readiness or leak tests, or visible damage to the valve and connector. Symptoms can also be subtle—difficulties with EVAP self-tests or an illuminated check engine light that points to vent or purge circuit faults are common indicators.

• Check Engine Light with EVAP-related trouble codes (e.g., vent control).
• Failed EVAP system leak or readiness tests during inspection.
• Broken electrical connector, stuck valve, or vacuum misbehavior.

How does the CVS6 compare to other replacements?

The CVS6 is produced to original equipment specifications, focusing on fit, function, and consistent electrical characteristics for two-terminal systems. Because it’s made in the United States, it follows factory tolerances and packaging dimensions that simplify installation and compatibility verification.

• OEM-grade construction for reliable fit and function.
• Compact package: 3.37" H × 2.00" L × 1.43" W for easy handling.
• Two electrical terminals that match many factory connectors.

How do I install the CVS6 safely and correctly?

Installation is straightforward for anyone familiar with EVAP components: disconnect the battery, depressurize the fuel/EVAP lines if necessary, unplug the two-terminal connector, remove the old valve, and install the replacement in the same orientation. Reconnect the electrical plug and hoses, restore power, and run the vehicle through an EVAP self-test or drive cycle to verify operation.

• Always disconnect the negative battery terminal before handling electrical parts.
• Label or photograph hose routing to ensure correct reassembly.
• Confirm correct connector seating and check for any vacuum leaks after installation.

Who is this for? The Standard Motor Products CVS6 vapor canister vent solenoid is intended for professional mechanics, repair shops, and experienced DIYers seeking an OEM-style, two-terminal EVAP vent replacement. It suits vehicles that require a compact, reliable vent solenoid and owners who want a U.S.-manufactured replacement part with standardized packaging and fit. If your vehicle exhibits EVAP-related fault codes or fails emission readiness checks, the CVS6 offers a direct, factory-oriented swap to restore intended venting behavior.
