New code can’t seem to figuerense out what’s the Problem

So I got an oil change they changed all my filters. New guy TA could tell he didn’t know much cuz I had to tell him what to do. Not the point but I just got this code. ENGINE 2 SPN 5357 FMI 16 I’ve clean the Venturi pipe I think it’s called and have change the sensor or what i belive it’s the temp sensor right behind the throttle body, Also change the EGR sensor, clean the injector on the passenger side. Do I need to reset the code. Can someone please guide me on the right direction
