ACDelco 214-1686 Vapor Canister Vent Solenoid GM OE Replacement

The ACDelco 214-1686 is a GM Original Equipment Vapor Canister Vent Solenoid — a critical component of your vehicle's evaporative emission control (EVAP) system. Engineered and validated by General Motors, this solenoid is a direct OE replacement designed to restore proper EVAP system function.

How It Works:

This solenoid valve controls airflow in and out of the charcoal vapor canister vent. When open, it allows the canister to breathe, venting air as fuel vapors are drawn into the engine. During EVAP system leak tests, the solenoid closes to seal the system, enabling accurate diagnostic readings.

Key Features:

• GM Original Equipment — the same part installed at the factory or validated by General Motors engineers
• Controls vapor canister venting to prevent fuel vapors from escaping into the atmosphere
• Closes automatically during EVAP system leak testing for accurate diagnostics
• Designed and tested to meet rigorous GM engineering standards for fit, form, and function
• Direct OE replacement — no modifications required for installation

Also referred to as an EVAP canister vent solenoid, canister vent valve, or vapor canister vent control solenoid, the ACDelco 214-1686 helps keep your vehicle's emission system operating within regulatory compliance.
