According to the search results, a 2007 Ford Taurus has four oxygen sensors. Two sensors are located in the front of the catalytic converter, and the other two are located in the rear.

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.
Do you need to replace all O2 sensors?
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.
Does my car have 2 O2 sensors?
Most cars have at least two oxygen sensors located throughout the exhaust system; at least one in front of the catalytic converter and one or more downstream from the catalytic converter. The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter.
How do I know if it’s my catalytic converter or O2 sensor?
To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge. This is your baseline vacuum.
How many oxygen sensors are on a 2007 Ford Taurus?
There are 4 o2 sensors on that engine. The two pre-cat units are on the exhaust manifolds above the “Y” pipe and the one can be a bit tricky. They call for a special wrench but with luck you can get them out with an open end wrench (some places like Auto Zone may loan or rent you the special socket).
How many O2 sensors do I have?
How Many Oxygen Sensors Are There in My Car? Most cars will have several oxygen sensors. There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
How long does it take to replace 4 oxygen sensors?
Oxygen sensor replacement is normally a straightforward job. If your car has upstream and downstream O2 sensors, the latter tends to be more accessible and the job and should take a home mechanic under an hour.
What are the symptoms of a bad O2 sensor?
Signs a Vehicle has a Bad O2 Sensor
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
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.
