Can you swap front and rear O2 sensors to get rid of code P0133? I have a new LS6 crate engine in my Trans Am and had pcmforless tune out the rear O2's for no cats. I have straight pipes in place of the cats and I'm getting a P0133-Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak
I checked under there and there is a tiny exhaust leak around the pipe so Im going to take it back to the exhaust guy on monday but if the sensor is bad will swapping them fix this?

No stock 2002 F-body LS1 exhaust manifolds and stock y pipe with straight pipes in place of the cats(for now)
After switching I drove the car about 40 miles then the light went out then came back on about 40 miles later and hasn't been out since.
I'm looking at some new sensors and I saw the NGK heated 4 wire ones 21528 and 21544 $104.06 for the pair at Amazon.com

Your exhaust leak may be your problem if it is in front of or near the oxygen sensor.
IF buying new ones I suggest the ones for the rear on the carvette as I think the heat range is/may be better and the wires are longer so when you go LT, I do not rember the # they may be the # you are looking at now .
yep just plug the rear holes

That's what I'm thinking too... the leak is near the sensor and I havent gotten it fixed yet because I'm waiting on a muffler I just ordered and I was going to do both in one shot but I might take it by there tomorrow and see if he can fix the leak first.
The rear corvette ones are # 21537 and I'll probably get those. They are $53.44 each
