Motorad 1VS115 Engine Variable Valve Timing (VVT) Solenoid

Engine VVT Solenoid for GM Applications

The Motorad 1VS115 engine variable valve timing solenoid is built for GM engines that rely on precise oil control to manage cam timing. It is a direct-fit replacement for a wide range of Buick, Chevrolet, Cadillac, GMC, Saturn, Pontiac, and Saab applications, including Buick Enclave, Chevrolet Traverse, and Cadillac CTS models.

• Electromagnetic activation for controlled VVT operation
• Black metal and plastic housing for engine-bay durability
• Plug-in rectangular connector with female connector gender
• Blade terminals with 2-wire, 2-terminal design
• Single mounting hole layout for OE-style installation
• Cross-references OE and aftermarket numbers including 916760 and 917219

How the 1VS115 Works

The Motorad 1VS115 VVT solenoid regulates oil flow to the variable valve timing system so the engine can adjust cam timing as operating conditions change. That helps restore proper timing response, support fuel economy, and reduce emissions on vehicles such as the Chevrolet Impala, GMC Terrain, and Cadillac SRX. The black connector and compact housing dimensions are suited to engine-management service where a direct electrical and mechanical match matters. This part number, 1VS115, is used across multiple GM platforms for consistent VVT control.

Common Symptoms This Part May Address

• Check engine light related to cam timing or VVT performance
• Rough idle or inconsistent engine response
• Reduced fuel economy from improper valve timing control
• Emissions concerns tied to VVT system faults
• Timing-related drivability issues on GM V6 and related engines

Installation Notes

Verify connector style, terminal count, and housing dimensions before installation. This solenoid uses a plug-in rectangular connector, female connector, and blade terminals, with no mounting hardware included. Clean the mounting area and inspect the engine oil condition, since contamination can affect VVT solenoid performance. Confirm vehicle-specific fitment for the exact year and model before ordering.
