Yes...
There are two oxygen sensors. One at the inlet and one at the outlet of the catalytic converter. The catalytic converter is behind the engine.
In the exhaust pipe before the catalytic converter, which is right behind the engine
There are two. One before and one after the catalytic converter behind the engine.
The Catalytic converter is located underneath the vehicle right behind the upstream oxygen sensor
Yes, it can affect the oxygen sensors and catalytic converter.Yes, it can affect the oxygen sensors and catalytic converter.
There are two. One is before the catalytic converter and one after. You will find them screwed into the exhaust behind the engine.
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.
The upstream sensor is screwed into the exhaust manifold behind the engine. The downstream is screwed into the pipe after the catalytic converter.
In front of and behind the catalytic converter.
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
that means your oxygen sensors, there are 2, one upstream and one downstream. One upstream is on exhaust manifold ,can be seen from engine , the downstream one is behind catalytic converter on exhaust .
Back of engine. One is in exhaust manifold, the other is screwed on behind hte catalytic converter.
