What is the purpose of the Evaporative Emissions Control (EVAP) system, Canister Purge Valves and Vapor Canister on Chevrolet Express?

To prevent fuel system vapours from escaping to the atmosphere, the Evaporative Emissions Control (EVAP) system is designed. On hot days, the fuel tank's trapped vapors expand and when pressure reaches a certain level, they flow through valves into EVAP canister for temporary storage. When conditions are right, the Powertrain Control Module (PCM) opens the canister purge solenoid, allowing vapors to be drawn into the intake manifold and consumed by the engine. The EVAP canister is usually located on top of gas tank between 1996 and 2002 or beneath car from 2003 onwards. A normally open EVAP canister vent valve closes off system during testing and pressure checks; it is placed close to canister. The vapor pressure in the fuel tank is monitored by a fuel tank pressure sensor which is located above it. Vapor flow into the intake manifold is regulated by PCM-controlled EVAP canister purge solenoid. Symptoms include odor of gas, rough idle, stalling and other drive ability problems. The presence of excessive fuel vapor pressure can be checked by removing the gas cap. To replace components: Disconnect battery remove and reinstall either purge solenoid or vent valve depending upon model years.

Chevrolet Express Canister Purge Valves

The Chevrolet Express Canister Purge Valves control the flow of fuel vapors so the van burns these fumes rather than letting them out, reducing emissions and saving gasoline. The Canister Purge Valves act like a controlled doorway between the charcoal canister and the intake manifold. In the event the engine computer detects normal temperatures and speeds, the Canister Purge Valves open. This results in intake vacuum pulling the stored hydrocarbons into the air fuel mixture for clean combustion. When they close, vapors stay trapped in the activated charcoal until the next purge cycle. Initially, Chevrolet Canister Purge Valves relied solely on manifold pressure. These older designs were simply vacuum operated. Later on, the Express Canister Purge Valves became electrically driven solenoid devices. These solenoid valves received orders from onboard diagnostics. Consequently, the computer sealed the system during its self tests and discovered a leak with the assistance of the fuel tank pressure sensor. Other than that change in actuation method, the two styles share a rugged build and the same mission of preventing hydrocarbons from escaping into the air. The Chevrolet Express Canister Purge Valves use a sealed pressure relief cap and a vent solenoid to help every Chevrolet Express vehicle comply with modern emission standards.

Each OEM Chevrolet Express Canister Purge Valves we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
