CEL confusion..

heykosal

Angkorian
so i did the paperclip thing and came up with code # 9 CYP number 1 cylinder position sensor

then with a "Honda Diagnostics Tablet" it threw code P1457 EVAP Emission Control System Leak (Control Canister System)

they told me its something called a vent shut valve may be stuck open, closed or it maybe in the wiring.

can anyone explain why the codes are so different?
