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.
EVAP Emission Control System Leak Detected (Control Canister System) code P1457 your probably looking at $140 for parts ($50 and change for vent shut valve, $80 and change for the canister) and about 2.2 hours of labor. If not it could be one of many things, Loose gas cap. EVAP bypass solenoid valve.
