Product Details

Gates VVS321 is an engine variable valve timing solenoid, also referred to as an oil control valve, used to regulate oil pressure to the VVT system. On the Honda Odyssey, Honda Pilot, Honda Accord, Honda Crosstour, Accord Crosstour, and Acura RDX applications listed above, proper solenoid operation helps the engine computer manage cam timing more accurately. This can restore smoother idle, stronger response, improved fuel economy, and lower emissions when the original unit is worn, sticking, or electrically faulty. This part cross-references Dorman OE Solutions 918-074 for the same application.

Common Problems This Part Can Address

• Check engine light related to VVT or oil control valve performance
• Rough or unstable idle caused by inconsistent cam timing control
• Reduced acceleration or sluggish throttle response
• Poor fuel economy from incorrect valve timing operation
• Emissions concerns tied to a malfunctioning VVT solenoid

Installation Notes and Tips

Verify the connector style, terminal count, and mounting location before installation. This solenoid uses a female connector, blade terminals, and electromagnetic activation, so matching the electrical and physical layout is important for a correct repair. Inspect the mating surface and related engine oil condition during service, since contamination can affect spool valve operation. For rear head spool valve applications, confirm the exact engine position shown in the vehicle service information before replacement.

Quality Assurance

Gates builds this VVT solenoid to OE specifications and tests it to help restore engine performance on the listed Honda and Acura vehicles. High-quality materials are used to support durability and maximum service life.
