I have these two codes on my SS:

P0155 - O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P1153 - Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1 (Front Bank)

Is this just a bad O2 sensor on my passenger side pre-cat?

I have SLP LT's, hi-flo cats, and SLP dual-dual exhaust. The sensors after the cat are disabled with O2 simms.

Thanks for the help.

Sounds like you burnt up the wires to the passenger side O2. Check the wires where they are very near the header.
