Human genetics: Pleiotropic mutations. Hannah Stower. A large-scale analysis of SNPs and genes that are reported to be associated with common complex diseases and traits has found abundant pleiotropy: that is, each individual gene mutation may have a role in multiple diseases. large-scale analysis of SNPs and genes that are reported to be associated with common complex diseases and traits has found abundant pleiotropy: that is, each individual gene mutation may have a role in multiple diseases.
EVAP Vent Valve. The evaporative canister vent valve not only allows the fresh outside air to the EVAP canister during the purge modes, but also allows the diagnostic to pull a vacuum on the fuel tank by closing the vent valve. This valve is normally open. EVAP Canister.
The EVAP Canister Purge Control Valve works with the Canister Purge SOLENOID valve. (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.I know, a bit confusing.)
