SES CODE, help
Does this mean a wire is messed up or is the o2 bad? The code came on one day and I went WOT and it went off, but they still pulled it. Then they cleared it and it is now back (3 days later).
P0157
O2 Sensor
Circuit Low Volts
(Bank 2 Sensor 2)
Is that driver or passenger? Sensor 2 is downstream from the cat, right?

B2S2 is the passenger side post-cat sensor.

both of mine came on before storage, P0137(drivers) and P0157(passengers) there the sensor's that monitor how your cat is working, you could have a cat that's clogging, or a bad sensor, if you have removed your cat or got long tubes i here they will throw it also, that's all I know just started looking into it though and will be fixing mine when the snow's gone and i can finally drive it again

I realise it is a non-essential item, but I figure I might as well fix it. Wouldn't it throw a code saying "Catalyst efficiency below threshold" or something instead of an O2 code? I was thinking bad sensor...($71.XX at advance auto).

I would guess a bad sensor or pinched/burned wire for a code like that.
