Emissions Vapor Purge Valve Location & info | Chevy/GMC 4.8L & 5.3L Engines. Silverado, Tahoe, Yukon

In this video, I show you the location of the emissions vapor purge valve on Chevy/GMC vehicles with 4.8L and 5.3L engines 🚗🔧. I walk you through how this valve works, the common trouble codes—such as P0440 (Evaporative Emission Control System Malfunction), P0442 (Evap System Small Leak), and P0455 (Evap System Large Leak)—and what they mean.

I also cover symptoms of a failing purge valve, like rough idle, hard starts after refueling, decreased fuel efficiency, and that annoying Check Engine Light 🚨. If you’re experiencing these issues, checking the purge valve could be the solution you need! 🛠️
