02 sensor question the bank 2 02 sensor is originally after the cat on the stock exhaust right?
if so then when i put my long tubes and true dual exhaust on that sensor should set the check engine because there is no cat there so it thinks its bad right?
when i got the pcm4less tune i told him no cats and the light still comes on.
should i just get the 02 sensor or is it getting a false reading due to no cat?

Was the oil temp 58, 59, or 79? Those are trans fluid codes. 16 is a low res failure which is a bad opti. Personally I'd be more worried about the opti than the O2. But about the O2, you're not going to get an O2 DTC because of the no cat I don't think. Either way, the oxygen in the exhaust at the O2 is going to be the same whether you have a cat or not so I would say the sensor is bad.
