OE Vapor Canister Vent Valve for EVAP Service

Standard Ignition CVS176 is a direct-fit vapor canister vent valve for evaporative emission system repair. It is built to match OE connector and terminal design for reliable electrical connection and consistent operation in the fuel vapor control circuit.

Compatible With select Cadillac, Chevrolet, Buick, and GMC applications, including Silverado 1500, Sierra 1500, Tahoe, Yukon, Escalade, Camaro, Colorado, and Traverse models. Standard Ignition CVS176 is used where a factory-style vent valve is needed to help keep unused fuel vapors sealed within the EVAP system.

Key Features

Direct-fit OE replacement for evaporative emission control service
1-port design for the specified vent valve application
Male blade terminals with 2 terminals for OE-style harness connection
OE-match connectors and terminals for proper fit to the engine wire harness
Industrial-grade plastic housing built to handle low and high engine temperatures
Standard Ignition CVS176 cross-references 2M1405 and 12630282 for the same application

Detailed Description

This vapor canister vent valve is engineered for EVAP system repair on a wide range of GM vehicles. Standard Ignition CVS176 helps maintain proper fuel vapor routing by sealing the vapor path when the system calls for it, supporting emissions control performance and drivability. It is a practical replacement for service on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and Chevrolet Camaro.

The part number CVS176 is built with OE-style terminals and connectors to promote a secure electrical interface and dependable conductivity. The housing material is selected for temperature resistance, making it suitable for underhood and evaporative system environments.

What It Helps Fix

EVAP leak-related diagnostic trouble codes
Fuel vapor escaping from the tank or canister area
Vent valve electrical connection issues
Rough EVAP system operation caused by a sticking or failed valve
Emissions inspection failures tied to evaporative system faults

Installation Notes and Tips

Verify the connector style, terminal count, and port configuration before installation. Confirm the vehicle application by year, make, and model, since fitment varies across Silverado, Sierra, Tahoe, Yukon, Escalade, XT5, and other listed platforms. Standard Ignition CVS176 is a direct-fit replacement, but the EVAP system should be inspected for damaged hoses, cracked fittings, or related faults before final diagnosis.

Quality Assurance

Standard Ignition maintains quality control throughout manufacturing, and this part is produced to OE-match specifications for fit and electrical connection consistency. The CVS176 is built as a factory-style replacement for evaporative system service.
