Standard VVT190T Engine Variable Valve Timing (VVT) Solenoid

Engine VVT Solenoid for GM Applications

Standard VVT190T is an engine variable valve timing solenoid used to control oil flow to the cam phaser system. It is a direct-fit service part for a wide range of GM, Cadillac, Buick, Chevrolet, GMC, Saturn, Saab, and Suzuki applications, including Buick Enclave, Chevrolet Traverse, and Cadillac CTS models.

Key Features

• Engine variable valve timing (VVT) solenoid for cam timing control
• Direct replacement for service on many GM-family engines
• Mounting hardware not included
• Standard part number VVT190T for catalog and search reference
• Cross-references Standard Ignition VVT190 for the same application

Detailed Description

The Standard VVT190T solenoid regulates oil pressure to the variable valve timing system, helping the engine adjust cam timing as operating conditions change. This part is commonly used on vehicles such as the 2008-2021 Buick Enclave, 2009-2023 Chevrolet Traverse, and 2004-2019 Cadillac CTS. It also serves many other applications across the GM platform, making VVT190T a practical replacement when diagnosing timing-related drivability concerns.

This part cross-references Standard Ignition VVT190 for the same application.

Common Issues This Part May Address

• Check engine light related to cam timing or VVT performance
• Rough idle or inconsistent engine response
• Reduced power caused by improper cam phasing
• Oil control issues affecting variable valve timing operation
• Timing system fault codes on supported Buick, Chevrolet, Cadillac, GMC, and related models

Installation Notes and Tips

Verify the connector style, mounting location, and engine code before installation. Inspect the oil passages and related seals for contamination or sludge, since restricted oil flow can affect VVT operation. Because mounting hardware is not included, reuse or replace fasteners as needed during service. Confirm fitment by year, make, and model before ordering.

Quality Assurance

Standard Ignition supplies replacement engine management components for service applications, and VVT190T is cataloged for broad OE-style fitment across multiple GM platforms. Use this part number, VVT190T, when matching the correct solenoid for your vehicle.
