Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
Which one? Upstream or downstream?
2 a upstream and downstream
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
Depends on what the problem is or what code was set.
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.
Two, an upstream and a downstream oxygen sensor.
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.
The upstream oxygen sensor is mounted in the exhaust manifold The downstream oxygen sensor is mountedin the exhaust pipe after catalytic converter
Get the check engine light looked at, the code will specify if it is the upstream or downstream sensor. The upstream will be on the exhaust manifold, and the downstream will be on the pipe after the catalytic converter.
usually, upstream means the one in the exhaust manifold and downstream is the one closest to the catalytic converter
