O2 sensor problem wierd

[03stanggt]

Got an 03 gt with and magnaflow system without Cats. I just had a new one put in because of damage to the old one. The rear O2 were shot for some reason. So I got new ones and bought the MILs from steeda. Now the trick is I bought the left side from my work( Checker Auto) the other I had to get from ford purple connector side. The O2 were installed correctly and all that stuff. I now have 2 codes vs the previous 4 without O2s. As follows: Bank 1 sensor 2 heater circuit malfunction. Pending code: Bank 2 sensor 2 heater circuit malfunction. Bank 2 is the ford sensor which might not have a problem. Steeda said there product shouldn't be a fault. I the Checker part crap and cause both codes to trip or is it the MILs? I am going to UTI and just took electronics, go figure I don't know what I am doing. Please help if you got a trick. Thank you

switch sides on both , erase codes and see what happens

Remove the MIL Eliminators, reset the PCM, and drive the car. When the MIL comes on again, scan the codes. You should only be getting the P0420 and P0430 codes. If thats the case, the MIL Eliminators aren't working correctly, or the connectors weren't snapped in tight.
