BANK 2 IS THE SENSOR LOCATED UNDER THE PASSENGER SIDE UNDER THE CHASSIS AFTER THE CATYLIC CONVERTER IT SREWED TO THE EXAUST PIPE THIS LINCOLNS HAVE A TOTAL OF FOUR OXYGEN SENSORS TO ON THE DRIVERS SIDE AND TO ON THE PASSENGER SIDE ON THE EXAUST PIPE Y CATYLIC CONVERTERS

Oxygen Sensor
There are actually (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions.
You will need;
Oxygen Sensor Socket
Anti-Seized
Penetrating Oil
I have even used a small plumbers propane tank and heat it up and it help get them free.
Sometimes it will take 15 minutes or take a few hours it depends on your luck…
where is the speed sensor for lincoln navigator
Speed Sensor The sensor is located on the rear axle housing.

where is the compressor sensor for a 2005 Lincoln navigator
On a 2003 Lincoln Navigator : The Mass Air Flow Sensor is located between the engine air filter and the big engine air intake tube . It is INSIDE a plastic housing , you will see where the wires go in at the bottom of the housing
Only4 - 2 front(before catalyst bank1,2),2 rear (after catalyst bank1,2)
On a 2000 Lincoln Navigator : Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine before the exhaust enter the catalytic converter ( upstream sensor ) Sensor 2 ( downstream sensor ) would be in the exhaust after the exhaust exits the catalytic converter
On a 1999 Lincoln Navigator : The Mass Air Flow sensor is between the engine air filter and the big engine air intake tube ( it is INSIDE the round shaped plastic housing )
Your local Lincoln dealer should Have it.
passenger side is bank 1 the closest to the engine is sensor 1 of the 2 on each side
Which o2 sensor are you looking for? The rear located near gas tank?
Bank 1 would be the passenger (right) side of engine. Bank 1 Sensor 2 would be the O2 sensor after the catalytic converter on the passenger side.
