Detailed Description

The Gates VVS277 variable valve timing solenoid regulates oil flow to the cam phaser system so the engine computer can adjust valve timing as needed. Proper VVT operation supports smoother idle, responsive acceleration, improved fuel economy, and lower emissions when the original solenoid is worn, sticking, or electrically faulty. Gates designs this Engine Variable Valve Timing Solenoid to match OE specifications and restore normal engine performance on 2014-2017 Ford Fiesta, 2015-2018 Ford Focus, and 2018-2021 Ford EcoSport applications. This part also cross-references Standard Ignition VVT335 for the same application.

Common Issues This Part May Resolve

• Rough or unstable idle caused by incorrect cam timing control
• Check engine light related to VVT or oil control valve faults
• Reduced power or sluggish throttle response
• Poor fuel economy from improper valve timing operation
• Emissions concerns tied to inconsistent cam phaser control

Installation Notes and Tips

Confirm connector style, terminal count, and OE part number before installation. Inspect the engine oil condition and related passages, since contaminated oil can affect solenoid operation. Replace the unit only after verifying the electrical circuit, connector condition, and any stored diagnostic trouble codes. This part does not include mounting hardware, a gasket/seal, or a mounting bolt.

Quality Assurance

Gates manufactures this VVT solenoid to OE specifications and tests it for performance consistency and service durability. The design uses quality materials intended to support reliable operation in daily driving conditions.
