Variable Valve Timing (VVT)

Variable Valve Timing Solenoids

BWD is proud to introduce a line of variable valve timing solenoids and sprockets. Scroll down to learn more about our newest product category.

Comprehensive Coverage for Variable Valve Timing

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 the components to fail prematurely.

Providing a premium quality replacement for this high-tech, high-failure category, BWD is proud to introduce a line of variable valve timing solenoids and sprockets. With more than 200 SKUs in the line, BWD provides comprehensive coverage for the aftermarket.

A Closer Look: VVT Solenoids and Sprockets

For an in-depth look at our solenoids and sprockets, watch this video from our "A Closer Look" series. To view all of the videos in the series, click here.


Variable Valve Timing Solenoids

Variable Valve Timing Solenoid


VVT solenoids can fail due to low engine oil levels and/or irregularly changed engine oil or filters.

For a high-quality replacement, BWD® VVT solenoids feature hard anodized components to ensure proper performance and long service life.

  • Hardened steel componentry limits sticking during sludge buildup
  • Premium O-rings and gaskets properly maintain oil pressure and prevent premature oil leaks

Variable Valve Timing Sprockets


VVT sprockets (a.k.a. cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency.

To ensure proper performance for this important category, BWD® VVT sprockets (a.k.a. cam phasers) meet tight dimensional tolerances to improve internal sealing, minimize oil drain back, and reduce frequency of PCM correction.

  • OE-matching sprocket tooth profiles ensure quiet operation
  • OE-style installation bolts included with sprockets for ease of installation
  • Precision-machined to ensure accurate variable valve timing, correct rough idle, and restore drivability

Another Line Expansion


One highlight from our latest 'New Parts Spotlight' is yet another expansion to our line of variable valve timing solenoids and sprockets. We've added 36 solenoids and 6 sprockets (a.k.a. cam phasers).

Designed and Tested for Real-World Conditions

In addition to providing comprehensive coverage, BWD is committed to supplying professional technicians with the premium quality that’s critical for this high-tech category. That’s why BWD® VVT solenoids and sprockets undergo an in-depth design process. Our continued commitment to high-quality design and testing standards ensures that each BWD® component will endure real-world conditions.


VVT Solutions for High-Failure Applications

Every variable valve timing 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 solenoids include the GM 2.4L and Toyota 3.0L and 3.3L. As you can see below, BWD has these applications covered.


Rattling Noises and Unstable Idle on GM 2.4L

Years: 2009-2010
Make: GM
Engine: 2.4L
Common DTCs: P0011, P0014, P0016, and P0017
Symptoms: Rattling noise at startup, unstable idle
Solution: Change the engine oil and filter
during maintenance intervals and following
solenoid replacement
Parts for the job: VV1098 and VV1099


Rough Idle on Toyota 3.0L and 3.3L

Years: 2001-2007
Make: Toyota
Engines: 3.0L and 3.3L
Common DTC: P1354
Symptoms: Rough idle
Solution: Maintain regular engine oil change
intervals. When replacing the solenoids, replace the
engine oil and filter.
Parts for the job: VV1056 and VV1057


Diagnosing VVT Repairs


Will a malfunctioning solenoid or sprocket affect the vehicle operation and/or cause MIL light to stay on?

Yes. They both can affect the vehicle operating condition and cause the MIL light to come on. They both can cause multiple codes to set.

What are common causes of VVT failure?

  • Lack of regular scheduled engine oil and filter service 
  • Incorrect engine oil added to the crankcase 
  • Clogged internal OCV (oil control valve) filter

Signs of malfunctioning VVT solenoids and sprockets:

  • MIL on 
  • Rough idle 
  • Poor performance 
  • Stalling/cutting out 
  • Engine noise

How to Replace a VVT Sprocket and Solenoid on a Ford 5.4L Engine

What you need to know:

Level of difficulty: ADVANCED
Approximate installation time: 4.5 HOURS
Vehicle used: 2008 Ford F250 Super Duty
Parts for the job: VV5000 and VV1001


Tips for Replacing VVT Components on Ford 5.4L Engines


Replacing the VVT sprocket (a.k.a. cam phaser) 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. 

  • Use a pick tool to make a scribe on the timing chain. The scribe will show you where to put the chain with the new sprocket to avoid retiming the engine.
  • 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:

  • Make sure the solenoid screens are clean. Buildup of engine oil sludge is a leading cause of solenoid failure
  • Tighten the solenoid hold-down bolt to 5Nm.

  • Perform an oil change following the repair. 

"On some systems, the intake camshaft is advanced at part throttle and WOT. The placement opens the intake valve sooner and allows some exhaust gas into the intake stroke, which has an EGR effect."
