According to the search results, the number of O2 sensors in a 2012 Dodge Durango can vary depending on the emission package. On certain non-California (Federal) emissions packages, the vehicle may use a total of either 2 or 4 sensors. In these cases, there is an upstream sensor (referred to as 1/1) located just before the main catalytic converter and a downstream sensor (referred to as 1/2).
Therefore, the 2012 Dodge Durango can have either 2 or 4 O2 sensors, depending on the emission package.

How much does it cost to replace the O2 sensor on a Dodge Durango?
Labor costs are estimated between $130 and $164 while parts are priced between $255 and $309. This range does not include taxes and fees, and does not factor in your unique location.
What would cause all 4 O2 sensors to go bad?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
Do you have to replace both O2 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream).
How many oxygen sensors does a 2014 Dodge Durango have?
2014 durango with the 5.7 engine. Replacing all 4 O2 sensors.
Will an O2 sensor work without a catalytic converter?
an O2 sensor does not need a cat to function properly. There are aftermarket fuel injection systems that use an O2sensors to keep fuel mixture anywhere you want, usually way richer then is safe with a cat. The sensor just reports free oxygen, the software it reports to does whatever it’s written to do.
How many O2 sensors does a v6 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 do I know how many O2 sensors 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 many O2 sensors are there?
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.
Do you need to replace both upstream and downstream 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.
