    Hello my Prius friends. Recently my 2015 went from 51mpg to 46mpg. I ran a OBD2, several codes have popped up: U0293, U0155, U0142, U0100, B2321 & B1206, C1311. I've checked all the wiring, fuses, all are intacted and no burn fuses. Was wondering if u or anyone you know had this same scenarios and figured out the fixed. O'Reilly guys tested the 12V battery, tested good. Also, I'm trying to locate 20A HEV fuse, but unsuccessful.
