Diagnose and fix poor engine performance in your Trax by understanding its VVT solenoids.
- The primary cause of VVT solenoid failure is old or dirty engine oil; regular oil changes are the best prevention.
- Look for diagnostic trouble codes P0010, P0011, P0013, or P0014 as a clear sign of a VVT system problem.
- It is strongly recommended to replace both intake and exhaust solenoids at the same time to ensure a lasting repair.
- This is a very DIY-friendly repair that can be done in under an hour with basic tools, saving on labor costs.
Is Your Trax Running Rough? It Could Be the VVT Solenoids
If your 2013-2022 Chevrolet Trax is experiencing a sudden drop in fuel economy, a rough idle, or has the Check Engine Light on, faulty VVT solenoids are a likely culprit. These parts are a common failure point, but the good news is that they are relatively inexpensive and easy to replace.
Symptoms of VVT Solenoid Failure
A failing VVT solenoid will almost always trigger a Check Engine Light. You can use an OBD-II scanner to check for specific codes. 🎬 Watch: How to fix fault codes P0010 and P0013 Beyond the warning light, you may also notice:
- Rough Idle: The engine may shake or sound unstable when you're stopped.
- Poor Performance: Your Trax may feel sluggish, hesitate during acceleration, or struggle to climb hills.
- Decreased Fuel Economy: An inefficiently timed engine burns more gas.
- Engine Stalling: In more severe cases, the engine may stall at low speeds.
- Engine Noise: You might hear a rattling or ticking sound from the top of the engine.
The Main Cause of Failure: Engine Oil
The number one cause of VVT solenoid failure is contaminated or low engine oil. The solenoids have fine mesh screens that can become clogged by old, dirty oil or sludge. 🎬 See how to diagnose timing codes caused by oil issues Sticking to your Trax's recommended oil change schedule with high-quality, full synthetic oil is the best way to prevent this problem.
Choosing the Right Aftermarket VVT Solenoid
For the 2013-2022 Trax, you have several aftermarket brands to choose from. While an OEM part from the dealer is an option, aftermarket parts offer comparable quality at a better price. It's highly recommended to replace both the intake and exhaust solenoids at the same time, as they wear at a similar rate.
- Premium Aftermarket (e.g., Standard Ignition, Gates, NGK): These brands have a strong reputation for producing reliable engine management components. Gates, for example, is well-known for timing-related parts. They are an excellent balance of quality and value.
- Value-Oriented Aftermarket (e.g., Dorman, Global Parts): Dorman is a widely available brand that often provides a direct-fit replacement. While some professional mechanics have noted concerns about the long-term durability of aftermarket electronic parts compared to OEM, they remain a popular and budget-friendly choice for a DIY repair. Many kits are available that include both solenoids for a complete job.

Do I have to replace both VVT solenoids at once?
It is highly recommended. The intake and exhaust solenoids experience the same conditions and wear at a similar rate. If one has failed, the other is likely not far behind. Replacing them in pairs saves you from doing the same job twice.
Can I just clean the VVT solenoid?
Some owners attempt to clean the solenoid screens with a degreaser as a temporary fix. However, failure is often electrical or internal. Cleaning a clogged screen doesn't fix a worn-out solenoid, so replacement is the only reliable, long-term solution.
Is there a recall on the Trax for VVT solenoids?
As of early 2026, there are no specific NHTSA recalls or widespread Technical Service Bulletins (TSBs) for VVT solenoid failure on the 2013-2022 Chevrolet Trax. Problems with this part are generally handled as individual repairs.
What's the difference between the intake and exhaust solenoid?
On many GM engines, the intake and exhaust solenoids are physically identical and can be interchanged. However, it is critical to verify the correct part number for your specific vehicle year and engine (1.4L or 1.8L), as some applications use distinct parts. They are identified by their position on the engine—one for the intake camshaft and one for the exhaust camshaft.
