usually, upstream means the one in the exhaust manifold and downstream is the one closest to the catalytic converter
before and after catalytic converter.
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.
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.
The 1996-2001 Elantra's have two sensors the upstream and downstream the upstream sensor is located the exhaust manifold and the downstream is located behind the catalytic converter.
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
On a 2005 Dodge Stratus, the oxygen (O2) sensor is typically located on the exhaust system. There are usually two sensors: one is positioned before the catalytic converter (upstream), and the other is located after the catalytic converter (downstream). You can find them attached to the exhaust pipe, with the upstream sensor generally closer to the engine. To access them, you may need to lift the vehicle for better visibility.
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
Which one? Upstream or downstream?
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
