Want this question answered?
It is located on the muffler by the moter and looks like a sparkplug with wire attached at the end. To be specific, my 2000 Durango has 1 upstream oxygen sensor and 1 downstream oxygen sensor. Both are located on the exhaust pipe. The upstream is between the engine and catalytic converter. The downstream is located between the catalytic converter and muffler. - Mick
The 4.7L 2002 dodge durango has 4 O2 sensors. ref. Chilton's Dodge Durango/Dakota 2001-03 repair manual. page 6-19 (Oxygen sensor - general info and replacement) The upstream oxygen sensor is located before the catalytic converter. The downstream oxygen sensor is located is located after the catalytic converter.
There is a problem with the downstream oxygen sensor. I would replace it.
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.
From underneath car there about 2' apart on either side of converter. Upstream is much harder then the downstream which is easy
Which one? Upstream or downstream?
Right after the catalytic converter or " downstream " of the converter.
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 oxygen sensor is located in the exhaust system on a 2005 Dodge Durango Hemi 5.7. There is a sensor located before and after the catalytic converter.
