The 2007 Ford 500 has four oxygen (O2) sensors. These sensors are located before and after the catalytic converter.

How do you know which oxygen 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 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.
What are the signs 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.
Can I drive 500 miles with bad O2 sensor?
Yes you can. If the engine detects a bad O2 sensor (one with illegal or out of range values, then it makes an assumption and the engine still operates.
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 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 are the 3 common causes of O2 sensor failure?
Below are the top reasons that cause the oxygen sensor to fail:
- Long Time Usage. The oxygen sensor as with all electrochemical sensors, loses sensitivity after long periods of use.
- Contamination.
- High Temperature.
- Irregular Maintenance.
- Using Low-Quality Gasoline.
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 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.
