Downstream O2s are on the outlet side of the catalytic converter(s).
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
it is the oxygen sensor afterthe cat conv
That is the oxygen sensor screwed into the downstream side of the catalytic converter.That is the oxygen sensor screwed into the downstream side of the catalytic converter.
Bank #1 is the passenger side of the engine , and sensor # 2 is in the exhaust after the catalytic converter ( downstream )
Which one? Upstream or downstream?
Right after the catalytic converter or " downstream " of the 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.
2 a upstream and downstream
The upstream oxygen sensor is mounted in the exhaust manifold The downstream oxygen sensor is mountedin the exhaust pipe after catalytic converter
The upstream oxygen sensor is mounted in the exhaust manifold The downstream oxygen sensor is mounted in the exhaust pipe after 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
On the 98 u have two oxygen sensors an upstream and a downstream. The upstream oxygen sensor is located closer to the front of the truck by the transmission. The downstream oxygen sensor is located on down torwards the back of the truck along the side of the frame.
