Standard Motor Products VVT170 Variable Valve Timing Solenoid

The Standard Motor Products VVT170 is a direct-fit, OE-replacement variable valve timing (VVT) solenoid engineered to restore precise camshaft timing control. This solenoid regulates oil pressure flow to the VVT actuator, enabling the engine control module to adjust camshaft position for optimized power, fuel efficiency, and emissions output across varying engine loads and RPM ranges.

Manufactured to exceed OEM specifications, the VVT170 features hard anodized steel construction that resists sludge buildup — a leading cause of VVT solenoid failure. Quality O-rings and seals are included to ensure a leak-free installation. Made in Japan, this solenoid delivers dependable, maintenance-free operation and a service life equal to or greater than the original equipment part.

Key Features:

• Direct-fit OE replacement — no modifications required
• Hard anodized steel components resist sludge and corrosion
• Restores engine horsepower, torque, and fuel efficiency
• Reduces emissions by maintaining proper camshaft timing
• Includes quality O-rings and seals for leak-free installation
• Manufactured to exceed OEM specifications
• Made in Japan

A failed or sluggish VVT solenoid commonly triggers symptoms such as rough idle, stalling, reduced power, and diagnostic trouble codes related to camshaft timing. Replacing the VVT solenoid at the first sign of symptoms — and simultaneously performing an engine oil and filter change — is strongly recommended for optimal results.
