From underneath car there about 2' apart on either side of converter. Upstream is much harder then the downstream which is easy
There is one upstream and one downstream There is one upstream and one downstream
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
Which one? Upstream or downstream?
2 a upstream and downstream
Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
ther are 2 oxygen sensors, an upstream and a downstream . The upstream is on driver side of engine exhaust and the downstream is back of catylitic converter agin on exhaust pipe.
usually, upstream means the one in the exhaust manifold and downstream is the one closest to 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.
Two, an upstream and a downstream oxygen sensor.
We need to know if your code relates to upstream or downstream errors. If it says downstream you are having a problem with the converters. If it states upstream there can be many reasons for the code. Is it running good. Bad. Smoking at all. Let me know and we can go from there
There is an upstream and downstream o2 sensor. The upstream is loctaed in the exhaust manifold before the catalytic converter. The downstream is located behind the catlytic converter.
