Number of O2 Sensors in a 2001 Ford Explorer Sport Trac
The 2001 Ford Explorer Sport Trac is equipped with two oxygen (O2) sensors. These sensors are located in the exhaust system, with one positioned before the catalytic converter and the other after the catalytic converter.
It’s important to note that the oxygen sensors play a crucial role in maintaining the gas to oxygen ratio by analyzing it to ensure the best mileage and keeping emissions in check.

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.
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.
What is the difference between sensor 1 and 2?
Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor. It is always going to be located after the catalytic 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 O2 sensors if one is bad?
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. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.
What symptoms does a bad O2 sensor cause?
First, what are the signs an O2 sensor may have gone bad?
- 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.
Which O2 sensor is more important upstream or downstream?
The catalytic converter turns harmful exhaust gases “safer,” so the gases entering it must leave with little to no pollutants. In short, the upstream O2 sensor must detect more pollutants than its downstream counterpart.
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.
