Answer:
The 2012 Ford Expedition has four oxygen (O2) sensors. These sensors are located before and after the catalytic converter. There are two upstream sensors, which are located before the catalytic converter, and two downstream sensors, which are located after the catalytic converter.
Replacing all four O2 sensors at the same time is recommended to ensure optimal performance and avoid future issues.

How many o2 sensors do I have?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
How many o2 sensors does a 2012 f150 Ecoboost have?
To the best of my knowledge all of the Boosts have 4 O2 sensors, though I believe the down stream ones are the same part number on some models.
Where are the 4 O2 sensors located?
Four-cylinder engines have two sensors, while V6 and V8 engines have four sensors. The upstream oxygen sensor(s) are located below the exhaust manifold flanges and above the catalytic converter. The downstream oxygen sensor(s) are located in the exhaust pipe, behind the catalytic converter.
Which O2 sensor should I replace first?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Do you have to replace both O2 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream).
Where is the o2 sensor located on a Ford Expedition?
I’m just going to use our o2 sensor socket. Here. We’ll get it on there and break this. Free. Next thing we would want to do is follow that wire to the connector.
How can I tell which O2 sensor is bad?
Performance by monitoring fuel air mixture. And catalytic converters. When they start to fail your fuel economy and emissions can be affected. It’s likely you’ll see a check engine.

How many O2 sensors does a 3.5 Ecoboost have?
4
Set of 4 New GAM Oxygen O2 Sensor Upstream & Downstream Compatible With 2011 2012 2013 2014 Ford F150 F-150 Pickup V6 3.5L Turbocharged Ecoboost.
Should I replace all 4 o2 sensors at once?
Do I need to replace all of the sensors at once? It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right.
