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.
They go by many names, but look for EVAP Valve or Vent Valve/solenoid & Purge Valve/solenoid. The one in the rear of the car, near the gas tank, is known as the Vent Valve Solenoid Canister..The one in the engine compartment is called a  Purge Valve Solenoid.. Replacing the one in the engine compartment did the trick. I'd start by replacing that one first then test it.hey go by many names, but look for EVAP Valve or Vent Valve/solenoid & Purge Valve/solenoid.
