Need to know where the heated oxygen sensor number 2 is located
Oxygen sensors are mounted either side of the catalytic converter. Number 1 is mounted before the cat in the down pipe and the Number 2 is in the exhaust pipe just after the cat, think the number 2 is the downstream.
SOURCE: Location of oil filter on Nissan Altima 2005
The oil filter is located behind the right (passenger) inner fender cover. It is right next to the crankshaft pulley at the bottom of the front of the engine facing toward the right front wheel. I do not have a picture at this time.
Hope this is helpful!

It is small and round (2 wire connector) and located either in the flexiable air intake hose to the engine or in the engine air filter housing.
SOURCE: How do I change brake light bulb on 2005 Nissan Altima
The first objective is to figure out which bulb you need. I had to replace the bulb for the largest light which was a Sylvania 3157. The next objective is to remove the dang plastic carpet holder/net clip. Recognize that it is a two part piece. Use a flathead screwdriver for leverage. Pry the cap off by levering the screwdriver in the slot on the holder. Then go behind the carpet and pinch the plastic pin still holding the holder in place. Next,pry off the while plastic pieces from the two bolt/nuts you'll need to remove (see manual). Remove the nuts and give the two screws a push from the inside so you can see how the whole light casing comes off. Pry it off from the outside. On the backside of the bulb holder, turn bulb base counterclockwise and gently remove. Pull bulb upward and replace. Do not touch glass on new bulb with your fingers (wear non-powdered rubber gloves). Make sure the bulb snaps in place. Follow these instructions in reverse. Smile, you just learned something new and saved yourself some easy money.
