you have 2 O2 sensors, an upstream O2 sensors located in front of the catalytic converter and the downstream is behind it either on the exaust manifold or the exaust manifold pipe
an o2 sensor is the same as an oxygen sensor. vehicles can have up to 4
Most oxygen sensors are heated oxygen sensors.

A 1997 Dodge Dakota has two oxygen sensors.
they are located in the exhaust system Where ? how many 02 sensors on a 2003 Pontiac Montana
There are approximately 4 oxygen sensors on a Chevrolet V6 truck. The oxygen sensors can be purchased at any auto parts store such as NAPA.
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
There are four oxygen sensors. Two are pre-catalyst and two are post-catalyst oxygen sensors. Basically, there is one sensor for each side of the engine in front of the catalytic converter and there are two sensors behind the catalytic converter.
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
No they can not unless someone has tampered with the plugin connectors.
Just after the air filter, toward the engine.
