Q: Where Is the Canister Purge Valve Typically Located?

Tips on How To Access the Canister Purge Valve

To find the canister purge valve, you can check on top of the engine near the carburetor or throttle body. Once you locate the purge valve, you can remove it by simply unscrewing it from the engine. If you’re having a difficult time finding it, try to follow the hoses from the intake manifold until you locate the purge valve.

There are a few parts you might need to move before accessing the canister purge valve. For instance, in the case of the 2014 Chevrolet Silverado, the canister purge valve is located underneath the air intake manifold, meaning you need to disconnect the manifold before reaching the purge valve. Compare that to the canister purge valves in the 2013-2016 Ford Escapes. These can be found next to the air intake below instead of beneath the manifold,  and they’re much easier to access.

Q: Where Is the Canister Purge Valve Typically Located?
A: As part of the Evaporative Emission Control System (EVAP), the canister purge valve bars fuel vapors from escaping into the atmosphere. Instead, the purge valve collects these vapors and, once enough pressure builds, releases them into the engine to burn.

The sentence: “the purge valve collects these vapors” is incorrect. It should correctly, read the EVAP “Canister” collects these vapors. The purge “valve” releases the vapors into the engine, but the “valve” does not collect the vapors.
