★ Top Answer
The evaporator canister, also known as the purge valve, on the 2002 Chevy TrailBlazer can be found positioned behind the muffler. This part holds around 1-2 pounds of activated charcoal that works by soaking up and holding onto fuel vapors until the purge valve triggers them to be drawn into the engine intake manifold by the engine's vacuum. Telltale signs that the evaporator canister is failing include the Check Engine Light turning on, a strong fuel odor at the rear of the vehicle, and issues like a compromised or leaking fuel tank.
