Before the exhaust gas passes through the catalytic converter ( s )
There are two upstream O2 sensors 4.0L V6 Upstream & Downstream Sensor Locations * Both upstream sensors are screwed into the exhaust pipe right below the exhaust manifold flanges * Both downstream sensors are located in the catalytic converters 4.6L V8 Upstream & Downstream Sensor Locations * The left upstream sensor is screwed into the exhaust manifold right above the manifold flange and the right upstream sensor is screwed into the exhaust pipe right below the exhaust manifold flange * Both downstream sensors are located in the catalytic converters
Upstream: you have been in a battle. Downstream: you have achieved your goal
Right upstream oxygen sensor heater failure.Right upstream oxygen sensor heater failure.
The Egyptian word for transportation. Upstream and downstream.
It is an Egyptian word for travel which meant to go upstream
Upstream and downstream refers to the supply chain of an industry. For example, if you're looking at a distribution plant then the manufacture would be downstream and the retailer would be upstream. Events or processes that happen before whatever is being looked at is downstream and whatever happens after is upstream.
Swimming upstream is to do something the hard way. It is more difficult to swim against the current. Salmon swim upstream in order to spawn.
I'm assuming you mean the upstream O2 sensor, which is "upstream" of the catalytic converter in the exhaust manifold or pipe.
Incoming rate or speed. As in download as opposed to upload or upstream.
upstream
one upstream and one down stream on in the manifold up stream the one in or behind the converter down stream
downstream and upstream
