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.

Most likely a bad O2. I was lucky, I got a set of 4 for $80. New they're like $90-$120 each

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

Or you could get some headers and turn the rear O2's off. They just detect if the cats are operating properly.
