Variable Valve Timing systems are designed to reduce emissions and maximize engine performance and fuel economy. The electro-mechanical system depends on the circulation of engine oil. Lack of oil circulation can cause components to fail prematurely.
Providing a premium quality replacement for this high-tech, high-failure category, NAPA Echlin is proud to introduce a line of variable valve timing solenoids and sprockets. With more than 260 SKUs in the line, NAPA Echlin provides comprehensive coverage for the aftermarket.

In addition to providing comprehensive coverage, NAPA® Echlin® is committed to supplying professional technicians with the premium quality that’s critical for this high-tech category. That’s why NAPA® Echlin® VVT solenoids and sprockets undergo an in-depth design process. Our continued commitment to high-quality design and testing standards ensures that each NAPA® Echlin® VVT component will endure real-world conditions.
Every VVT system is slightly different, but there are three general rules to follow to ensure proper performance. First, regularly service the engine oil and filter. Second, use the manufacturer’s required engine oil type. Lastly, service the engine oil and filter after you install new solenoids or sprockets.
A few specific applications that are known to have high failure rates for VVT solenoids include the GM 2.4L and Toyota 3.0L and 3.3L. As you can see below, NAPA® Echlin® has these applications covered.
Common DTCs: P0011, P0014, P0016, and P0017

Replacing the sprocket on a Ford 5.4L engine is an in-depth job. To help you replace it correctly, here are a few repair tips from our Installation Spotlight video.
Remove the entire camshaft. Otherwise, it will be difficult to align the sprocket’s dowel pin. If the pin isn’t aligned perfectly, it will be sheared off, causing damage to the camshaft.
Tighten the sprocket bolt to 40Nm, then tighten an additional 90 degrees.
Torque the camshaft caps to 10Nm, working your way from the center to the outside
If you’re replacing the sprocket, our Master Technicians recommend replacing the solenoid, too. Here are a few repair tips to keep in mind during the replacement:
Tighten the solenoid hold-down bolt to 5Nm.
