EVAP Evaporative Emission Control System The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.

- The evaporative emission (EVAP) control system limits the fuel vapors from escaping into the atmosphere. The EVAP transfers the fuel vapors from the sealed fuel tank to an activated carbon storage device, the EVAP canister. The EVAP canister stores the vapors until the engine is able to use the extra fuel vapor.When the engine is able to use the extra fuel vapor, the intake air flow purges the fuel vapor from the carbon element and then the normal combustion process consumes the fuel vapor.anister Vent Restriction Test: This tests for a restriction in the EVAP vent system. The FTP sensor looks for sufficient vacuum from the engine intake manifold. After a period of time and conditions have been met, this test will pass.

- The larger diameter hose directly below is vacuum coming from the EVAP canister. The opposite large diameter hose is vacuum going to the EVAP canister purge volume control valve. (I have a video link below for these components.) If you get stuck along the way just shoot me an email and I'll do my best to help out.Cheers.I know, a bit confusing.) When vacuum signal is cut by the Solenoid Valve, the control valve shuts off the EVAP purge line. The control valve in this vehicle has three vacuum hookups. The thin hose on top is vacuum coming from the solenoid valve.
