Where is the Purge Valve located on a 2014 Subaru Forester? A Step-by-Step Guide to Troubleshooting and Maintenance

Maintaining a car can be a daunting task, especially if you’re not familiar with the intricate workings of your vehicle. The Subaru Forester is a popular SUV that requires routine maintenance to keep it working efficiently. One of the essential components that need regular maintenance is the purge valve. This article will explain what a purge valve is, how it works, the signs of a malfunctioning purge valve, and the steps to locate the purge valve in a 2014 Subaru Forester. Additionally, this article will provide helpful tips on how to properly maintain your purge valve to prevent further issues.

What is a Purge Valve and How Does it Work?

The purge valve is a critical component in modern vehicles equipped with Evaporative Emissions Control Systems (EVAP). This system helps to prevent fuel vapors from escaping into the atmosphere by gathering them and then burning them inside the engine. The purge valve opens and closes a pathway between the charcoal canister and the engine’s intake manifold, allowing the fuel vapor to enter the engine when it is running.

When the engine is off, the EVAP system uses the purge valve to create a vacuum that traps fuel vapor in the charcoal canister. Then, when the engine is running, the valve opens, allowing the fuel vapor to be drawn into the engine and burned along with the fuel/air mixture.
