o2 Sensors?

[19ClearCobra96]

I got a trouble codes of
p0151, which is sensor circuit low voltage(bank2 sensor1)
p1131, Lack of HO2S1 switches - lean(bank1 sensor1)
p1151, Lack of HO2S1 switches - lean(bank2 sensor1)

I guess I'm wandering what these mean and which sensors the bank# sensor# ?

Sounds like your cats are clogged or that 8 inches of snow messed some of the oxygen censors up

ah chit i cannt member bank one i believe is the pass. side where #1 cyl is and sensor one is the pre cat sensors on both sides
usually if they fail they say lean but the odds of 2 failing on opposite sides are slim to none id say. ho2s1 means its not getting any carbon dioxide wich means severe miss fire or poss. an exhaust leak..... did you get it started??????
