My friend has an 02SS with slp long tubes that go into random tech cats through an slp y-pipe. there is a sensor before both cats and a sensor after both cats and he has a p0135 02 sensor code, which sensor is the bad one drivers side or passenger side and the one before or after the cat??

Thanks guys

•DTC P0135 for HO2S bank 1 sensor 1 which is driver's side pre-cat.
