Is Your Equinox Running Rough? It Could Be the VVT Solenoid
If you own a 2008-2024 Chevrolet Equinox, especially one with the 2.4L Ecotec engine, you may eventually face issues with the Variable Valve Timing (VVT) solenoids. This is one of the most common failure points on these engines. The good news is that it's a relatively inexpensive and easy part to replace yourself.
Known Issues: GM Technical Service Bulletin (TSB)
For 2010-2012 Equinox models with the 2.4L engine, General Motors issued Technical Service Bulletin #17-NA-098. 🎬 Watch this step-by-step guide to fixing Equinox stalling issues. This bulletin addresses customer complaints of a rough running engine, hesitation, stalling, and specific check engine light codes (P0010, P0011, P0013, P0014). The official recommendation from GM is to replace both the intake and exhaust camshaft position actuator solenoid valves.
Common Symptoms of a Bad VVT Solenoid
- Check Engine Light: This is the most common symptom. The light will be on with codes like P0010, P0011, P0013, or P0014 stored in the computer.
- Rough Idle and Stalling: Your Equinox may shake at stoplights, idle erratically, or even stall completely, especially at low speeds.
- Poor Fuel Economy: When the valve timing is incorrect, the engine burns more fuel than necessary.
- Reduced Engine Power: The car may feel sluggish and hesitate during acceleration.
- Engine Noise: In some cases, you might hear a rattling or ticking noise from the top of the engine.
Check Your Oil First!
The VVT system relies on clean engine oil and proper oil pressure to function. Before you assume the solenoids are bad, check your oil level and condition. Low or dirty, sludgy oil is a primary cause of VVT solenoid failure and can produce the exact same symptoms. An oil change might be all you need.
Choosing the Right Aftermarket VVT Solenoid
You have many brands to choose from. While an OEM part from the dealer is an option, quality aftermarket parts offer excellent value and are a very popular choice for this repair.
- OEM-Grade (Tier 1): Brands like ACDelco are the original equipment manufacturer for GM. They offer a direct fit and factory performance, but are usually the most expensive option.
- Reputable Aftermarket (Tier 2): Brands like Dorman, Standard Ignition (SMP), Spectra, and Holstein are well-known in the industry. They provide a balance of quality and cost, often meeting or exceeding OEM specifications. These are a solid choice for most owners.
- Value Brands (Tier 3): There are many lower-cost options available online. While some may work fine, quality can be inconsistent. Given the low cost of reputable brands for this specific part, it's often worth spending a few extra dollars for a part with a better track record and warranty.

Frequently Asked Questions (FAQ)
Should I replace both VVT solenoids at the same time?
Yes. It is highly recommended to replace both the intake and exhaust solenoids together. They have been exposed to the same conditions (heat, oil, mileage), so if one has failed, the other is likely not far behind. This saves you from having to do the same job twice.
Can I just clean my old VVT solenoids?
While some people have temporary success cleaning the screens on the solenoids, it is not a reliable long-term fix. The failure is often internal to the solenoid's electronic components. Since new aftermarket parts are affordable, replacement is the best course of action.
🎬 See how to address P0013 and P0014 codes yourself.Is this a difficult repair to do myself?
No, this is considered a very easy DIY job. The solenoids are on top of the engine, right under the plastic engine cover. The repair typically takes less than 30 minutes and requires basic tools like a 10mm socket.
🎬 Watch a quick walkthrough of the 2.4L solenoid replacement.How do I know which solenoid is intake and which is exhaust?
On the 2.4L engine, the intake solenoid is the one closer to the front of the vehicle (towards the intake manifold), and the exhaust solenoid is the one closer to the back (towards the exhaust manifold). They are often different colors (e.g., one black, one grey) to help with identification.
