Bosch or Denso Downstream o2 sensor?
02max77k first got the p0430 went off then re appeared with p0139 and p1147 which refer to the oxygen sensor by the oil pan. Which is a more reliable OEM?

Bosch is OEM Nissan I believe and cheaper than Denso usually.

Wow, I watched a youtube video on it. The guy ended up cutting the wire from the old o2 sensor to remove it, and took several minutes just to remove the front clip from the engine bay. From the looks, you need to push in with a flat head while pulling out at the same time. Is there a special tool I need? the part number is 15225

The only tool youll need is an o2 sensor socket. You could use a wrench, but the socket prevents stripping. Soak the sensor for a day or two and its no big deal. Also for the plug, be very careful with it bc they will break like a dry noodle, ask me how i know. But yes, pry down with flat head then pull away with your hand

Oh ok, so I will spray some wd40 around the sensor, The plug is my biggest concern, and the main reason I have thought of having a mechanic do this. What happens if the plug breaks? Any tips for preventing this from happening?

Dont use WD40, its not a penetrating fluid. Use any sort of penetrating fluid. For the sensor plug theres not much you can do. The new one should come with the plug, but if youre really worried about breaking it, spray some spray silicone on it and let it sit for a couple days, might help it absorb some moisture. I think one or two of mine broke and i just zip tied them together

What if I already sprayed the sensor with wd40. Did it just do nothing to loosen it?

It wont hurt it, you could only have helped it. Im
just saying WD 40 wont be nearly as effective as something like pb blaster
