Upstream
downstream upstream streamline mainstream bloodstream airstream
both. upstream is under the hood, and the downstream is by the catalytic converter.
it refers to the location of the oxygen (o2) sensors relative to the engine. The upstream sensor is the one closest to the engine. The downstream sensor is furthest from the engine. Think of it as the way a stream of water, or in this case, a stream of exhaust flows.... From the engine To the tailpipe.
It has both an up and a down stream oxygen sensor.
The up stream is closest to engine and down stream is farest from engine
A riverboat with a steam powered engine that could travel either upstream or downstream was called a steam boat.
There is one upstream and one downstream.
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
it depens on if your truck has local or federal emmosions package if its federal ther eare 4, upstream and down stream on both sides.other wise there are only two upstream and downstream of the catalytic converter
they could sail upstream and down stream
