2005 Nissan Altima 2.5L - where is the heated oxygen sensor number 2 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.

Dose the buick park avenue use a map sensor or a mass air flow sensor. or are they the same thing

They are different types of sensors, but in your car the MAP (manifold absolute pressure) sensor, along with the BAROmetric sensor are used to estimate the required fuel flow through the throttle body injectors. These sensors measure pressures inside and outside the engine to estimate airflow. You do not have a MAF sensor. These are more common in later vehices with mulit-port fuel injection. A MAF sensor actually measures the airflow into the engine using a hot wire anemometer. You are correct in believing the sensors serve the same purpose, that is to calculate the fuel flow required for stoichiametric combustion. The oxygen sensor also feeds back to the computer to further refine the fuel charge by measuring oxygen in the combustion products. If excess oxygen is detected, the fuel charge is increased. This is known as closed-loop operation. Closed loop operation is not started until the engine is at operating temperature. If you have more questions, please let me know. I have pasted the location of the MAP sensor below. The sensor is mounted to the air cleaner, but it has a vacuum hose that leads to the throttle body, which is where the pressure must be measured.

Location of oxygen sensors

I think there is more than two. Either way, they are located in the exhaust system. The pre-cat sensors are in the head pipes, just below the exhaust manifold, and then there will be one right behind the catalytic converter. You will need a 7/8 inch wrench or possibly a special O2 socket.
