What is the purpose and function of the Canister Purge Valves, Fuel Pressure Sensor and Vapor Canister on Pontiac G6?

The Evaporative Emission Control which is abbreviated as EVAP system is aimed at avoiding fuel system vapors that contain unburned hydrocarbon from being released to the atmosphere. In main warmer, fuel vapors in the fuel tank get to expand and, once a given pressure is attained, they are directed through the fuel vent valve and the fuel EVAP control valve and into the canister for storage until consumed with the engine. The canister purge solenoid is controlled by the Powertrain Control Module (PCM) and the PCM opens it in certain conditions to let the vapours to fill the intake manifold to join the air/fuel mixture before combustion. The EVAP canister is the part of the vehicle situated beneath the car near the fuel tank and packed in the activated charcoal; the EVAP canister is reasonably maintenance-free. The fuel tank pressure sensor contributes detecting the pressure of the tank as well as signaling the PCM during tests with leaks. Located in the intake manifold vacuum and sensor, normally open, the vent solenoid seals the EVAP system for maintenance and testing, while the canister purge solenoid closes the system under the control of PCM. Diagnosing an electrical issue in EVAP system may not be easy but the symptoms which may suggest some goofs in the system include fuel smell, poor idle, stalling and low drive ability due to bad parts or the system having some leak. To ensure that fuel vapor pressure is not high, the gas cap can be unbolted and special sound, WHOOSH, which means pressure issues or hoses/valves, can be produced. Component replacement is usually accompanied by the removal of electrical connectors and hoses, the removal of the mounting brackets and every other related part, and then tightening and connecting where required in the reverse manner.

Pontiac G6 Canister Purge Valves

Pontiac G6 Canister Purge Valves ensure that fuel vapor which is stuck inside your fuel tank does not vent to the atmosphere but instead makes its way to the intake so it can be burned. These Canister Purge Valves open in the presence of engine vacuum, allowing fresh air to sweep through activated charcoal that has absorbed gasoline vapor. The resulting mixture is then conducted back to air fuel charge for clean burning. The main advantage they offer is the reduction of smog-forming hydrocarbons while also preventing pressure build-up in the fuel tank that may damage it. The first prototypes were simply linked directly to vacuum signals, but over the years Pontiac added controlled solenoids managed by the engine computer so that the system could run self-checks and set lights if leaks were detected. Subsequent G6 models feature an additional vent solenoid and a tank pressure sensor that work in conjunction with the Canister Purge Valves. Together, they seal the emissions system during tests to show proof of a steady vacuum hold. If the vacuum is not detected twice in a row, the computer will store a trouble code. This trouble code would normally point at a loose fuel cap and not the Canister Purge Valves. All G6s, regardless of year, use these little valves and the charcoal canister to trap vapors when parked and purge them when the engine fires up. This is the task the G6 Canister Purge Valves undertake on every Pontiac.

Each OEM Pontiac G6 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.

Diagnosing an electrical issue in EVAP system may not be easy but the symptoms which may suggest some goofs in the system include fuel smell, poor idle, stalling and low drive ability due to bad parts or the system having some leak. To ensure that fuel vapor pressure is not high, the gas cap can be unbolted and special sound, WHOOSH, which means pressure issues or hoses/valves, can be produced. Component replacement is usually accompanied by the removal of electrical connectors and hoses, the removal of the mounting brackets and every other related part, and then tightening and connecting where required in the reverse manner.
