Oxygen sensors are located in exhaust manifolds or in exhaust pipes before and after the converters in most cars depending on the year of the vehicle
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
Sensor one is in the exhaust manifold on the back of the engine. Sensor two is in the side of the catalytic converter.

It is located on the muffler by the moter and looks like a sparkplug with wire attached at the end. To be specific, my 2000 Durango has 1 upstream oxygen sensor and 1 downstream oxygen sensor. Both are located on the exhaust pipe. The upstream is between the engine and catalytic converter. The downstream is located between the catalytic converter and muffler. - Mick
A/F sensor are located in each exhaust manifold, O2 sensor After catalytic converter on exhaust pipe
It is the sensor in the outlet of the catalytic converter.
the coolant sensor is in the radiator on the passanger side the oxygen sensor is in the exhaust system on the manifold and the pipes and sometimes both
One is located on the downpipe and the other is located before the cat (On the infamous u-bend).
They are located in the exhaust system, rearward of the manifolds, and again after the catalytic converter.
A 2000 Dodge Ram diesel does not have an oxygen sensor.
