Number of O2 Sensors in a 2001 Ford Taurus
The 2001 Ford Taurus is equipped with four oxygen sensors. Two are located in the front of the vehicle, near the exhaust manifold, and two are located in the rear, near the catalytic converter. These oxygen sensors work to monitor the air/fuel mixture in the engine and ensure that it is burning efficiently. If they detect that the mixture is too rich or too lean, they will send a signal to the engine computer to make adjustments.
So, the 2001 Ford Taurus has a total of four oxygen sensors, with two located in the front and two in the rear of the vehicle.

Should I replace both O2 sensors?
Yes, you have to replace 2 Oxygen sensors if your car has one catalytic converter with one exhaust pipe. One sensor is in the front and another one is after the catalytic converter and remember don’t mix them up, the one for upstream before the catalytic converter is different from the one behind the converter.
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.
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.
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.
Are oxygen sensor 1 and 2 the same?
What is Sensor 1 & 2? The sensor number is telling us where on the exhaust system the O2 sensor or Exhaust temperature sensor is mounted. The 1st sensor is located closest to the engine and the last is located at the rear of the exhaust system.
Do you have to replace both O2 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream).
Do you need to replace both upstream and downstream O2 sensors?
Yes, you have to replace 2 Oxygen sensors if your car has one catalytic converter with one exhaust pipe. One sensor is in the front and another one is after the catalytic converter and remember don’t mix them up, the one for upstream before the catalytic converter is different from the one behind the converter.
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.
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.
How many oxygen sensors does a 2002 Ford Taurus have?
Your Taurus has (4),there are two upstream O2 sensors and two downstream O2 sensors or they are also called cat monitor sensors.
