Default Code 9 or 90

I replaced my TB and everything seemed fine. Week later i got a checkengine light , i didint think anything of it so i reset the ecu. So another week went by and it came back, turns out its code 9

CYP Sensor (Cylinder) defective circuit or unplugged / defective sensor
* invalid code for throttle body injection Hondas
** invalid code for V6 engines

I need some input on how it goes bad , is it related to TB and where is it located

------------------------------

unless its code 90 = Evaporative Emission Control System leak detected in the fuel tank area . It might be it since i have never seen the diff between the short flash or long flash

I checked the gas cap and it was fine so i am lost
