Chevrolet Malibu Engine VVT Solenoid Guide (2016-2025)
Diagnose and replace the VVT solenoids on your 2016-2025 Malibu to restore engine performance and fuel economy.
- VVT solenoid failure is very common and primarily caused by dirty or low engine oil.
- Symptoms include a rough idle, poor performance, bad gas mileage, and specific check engine codes (P0010, P0011, P0013, P0014).
- This is an easy and inexpensive DIY repair that most owners can do in under 30 minutes with basic tools.
- Always replace the solenoids in pairs and change the engine oil and filter at the same time for best results.
Is Your Malibu Running Rough? It Could Be the VVT Solenoids
If your 2016-2025 Chevrolet Malibu is experiencing a rough idle, poor acceleration, or a sudden drop in gas mileage, faulty Engine Variable Valve Timing (VVT) solenoids are a likely culprit. These parts are a common failure point, but the good news is that they are inexpensive and surprisingly easy to replace. The main cause of failure is often contaminated or old engine oil, which clogs the fine mesh screens on the solenoids and prevents them from working correctly.
Choosing the Right Aftermarket VVT Solenoid
Your Malibu has two VVT solenoids: one for the intake camshaft and one for the exhaust. 🎬 Watch: Step-by-step guide to replacing the exhaust VVT solenoid. They are often the same part number and it is highly recommended to replace them as a pair. Since they have been exposed to the same conditions for the same amount of time, if one has failed, the other is likely not far behind.
When shopping for replacements, you'll find several brands available:
- OEM / Premium Aftermarket (ACDelco, Standard Ignition Blue Streak): ACDelco is the original equipment manufacturer for GM vehicles. Choosing ACDelco guarantees a perfect fit and original performance. Brands like Standard Ignition's Blue Streak line also offer premium, high-quality components that are engineered to meet or exceed OEM standards.
- Standard Aftermarket (Dorman, Gates, Motorad): Brands like Dorman are well-known in the aftermarket and offer a reliable, cost-effective alternative to OEM parts. They provide a good balance of quality and value for a daily driver.
- Economy Aftermarket (Skyward, Global Parts, various online brands): These are the most budget-friendly options. While they can get your car back on the road, their long-term durability and performance may not match that of premium or standard brands.
Pro Tip: Regardless of which brand you choose, the most important thing you can do to protect your new VVT solenoids is to change your engine oil and filter at the same time as the replacement. Use the manufacturer-recommended oil viscosity to ensure proper system operation.

Known Issues, Recalls, and TSBs
As of early 2026, there are no active recalls specifically for the VVT solenoids on the 2016-2025 Chevrolet Malibu. However, GM has issued Technical Service Bulletins (TSBs) and special coverage for similar oil-pressure-related components, like the rocker arm oil control valve, on earlier model years with similar engines. This highlights the sensitivity of these engines to oil quality and maintenance. The most common issue remains failure due to oil contamination.
Frequently Asked Questions (FAQ)
How many VVT solenoids does my 2016-2025 Malibu have?
Your Malibu is equipped with two VVT solenoids. One is for the intake camshaft and the other is for the exhaust camshaft. They are located on the top of the engine under the plastic engine cover and are easily accessible.
Can I replace just the one that failed?
While you can replace just the single failed solenoid, it is highly recommended to replace both at the same time. They are the same age and have been operating under the same conditions. If one has failed due to mileage or oil contamination, the other may fail soon.
Is this a difficult repair to do myself?
No, this is considered a very easy DIY repair. The job requires basic tools like a 10mm socket and a Torx bit for the engine cover. The process involves removing the cover, unplugging the electrical connector, removing one bolt, and swapping the solenoid. The entire job can typically be done in under 30 minutes.
