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
If everything else fells there always heat. Heat them up and they will come right off.
Sometimes it will take 15 minutes or take a few hours it depends on your luck…

There are 4 oxygen sensors on the 2001 ford f150 v6.

They are located on the exhaust right before the cats.
There usually on the exhaust header
On my 1998 there are 4. Two on each side, one in front of the first cat and one after the second one, on both sides.
O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
You must mean Oxygen sensors. There are 2 upsteam (O2 sensors) and there are 2 downstream (catalyst moniters).
where are the oxygen sensors on a 2004 ford escape with a 3.0 engine
On a 1997 Ford Taurus : In the power distribution box ( which is " live " ) located in the front of the engine compartment , near the battery ( mini fuse # 28 is a 15 amp fuse for the heated oxygen sensors and canister vent )
My 1995 Ford Explorer with 4.0 L OHV has 2 oxygen sensors (Helpfull)
Two, one in front of the cat and one after the cat. Now if you have the optional duel exhaust you would have four.
No, a 1997 Ford F150 doors will not fit on a 2001 Expedition. You will need to get a door that is made specifically for the Expedition.
