New o2s...still throwing bank codes Hi All:
I just put 2 new o2s on my car (no cats or rear o2s), however its still throwing codes. Wondering if anyone has run into this before? I had the codes deleted...drove the car for a few days...had it checked again and they were there again.

P0134 - HO2S Circuit Insufficient Activity Bank 1 Sensor 1
P0154 - HO2S Circuit Insufficient Activity Bank 2 Sensor 1
They were cleared with a handheld code reader...drove the car...then they were thrown again on the handheld within a few days. The ECM prolly shot the codes sooner it was just a few days before I could check it again.

I checked the all the fuses on the passanger side under the hood but all still are good, where exactly on the fuses that would run the o2s?
I have LTs with 3in piping all the way back into a single flowmaster, CAI, etc. No cats.
Let me know if you can think of anything else...I'll continue to trace it and report back.

On a 96...do the front and rears have different connecting ends? Square or Flat connector?
What kind of connection are on the front o2s?
The front o2s are the square connector on my car.

disconnect your battery
bypass the harness with some new wire ( FROM SENSOR TO THE CLOSEST SPOT TO YOUR ECU. ONLY ON 1 BANK) then reconnect your battery and restart your car. that way you can see if your wiring is bad before you go nuts
