New Oxygen Sensor, but Engine light went on? Wait for it to go off or need OEM??

Hi Pushrod, thank you for your time and reply. Code is P0032, P0032, P0032 ----3 of the same codes. There is a newer catalytic converter I had installed 2 years ago, so I had a recent "Full" inspection and the mechanic said the catalytic converter is "blue" and I may want to change the Oxygen sensor. Soo after weeks of loosening the heat cover, I finally changed the Oxygen sensor last week, 7/16/2017. I was able to drive it today. The engine light went on, so I went and got the codes. The car stalled and won't start. I had placed the original oxygen sensor back and it still won't start. I had repaired laptops and computers for years and I like to change the old parts and fix my own car when I can and if I can.

Well you just might be in luck! .. This POO32 code indicates a 02 sensor 'heater circuit' fault .. The most likely cause is a blown fuse in the under hood fuse/relay box .. Look for a fuse marked 02 htr or the like, owners manual usually helpful when searching for fuse locations and functions .. Full index is in back of book .. See > FUSES... I prefer 'TESTING' all of the fuses with key on - using a 12 volt test light, takes about 5 minutes ! .. Since you're familiar with electronics .. Fuse testing procedure using a test light should be self explanatory... Volt meter will do the job, just takes longer I think.
