P1157 fix - already tried new sensor
 

So I have a P1157 on my 2003 accord (AT with a K24A4) which I read is a problem with the front o2 sensor

I replaced the front O2 sensor with a bosch unit and disconnected the battery

Within a few seconds of connecting everything and starting the engine, the code came right back.

What could it be? Is there a fuse somewhere that pops and can throw this code? A short in the harness? This is the only code that pops up, other than the code the car runs and drives great
