o2 sensor help ASAP
 

i have to pass the obd2 test by november.

i have a 98 civic. the front sensor reads. the rear doesnt im not sure if the plug is messed up or anything.
I put a good sensor in the rear bung but it still wouldnt pick up. we hooked it up to a computer. i took the o2 sensors off when i put my header on untill i got my extender wires.. and they worked before why not now?

tryuing to figure this out help would be appreciated
