Diagram of the location of a down stream o2 sensor on a 2005 chevy malibu.


Hi,
Downstream sensor is screwed into exhaust pipe after the catalytic converter on most models. Depending on your exhaust configuration, your code will say bank 1 or bank 2 or no bank designation. Some have converters coming off each cylinder bank (exhaust manifold off cylinder head) if only 1 converter in system (no bank) there will only be the one O2 sensor downstream.

What is the location of the FUEL AIR RATIO SENSOR on a Subaru Outback, 2001,. 2.2 L ?


since that is a Boxer engine it will have one O2 sensor at the base of each exhaust manifold. and since it is newer than a 1996 it will have one or two more O2 sensors behind each catalytic converter so you will have three or four ( O2 sensors) fuel air ratio sensors you need to check if you are having a problem. the two at each exhaust manifold are the upstream and the ones at the catalytic converters are the downstream. hopefully that engine only has one catalytic converter going into one exhaust pipe. the exaust manifolds are under the engines cylinder heads (under the engine).

Exact location of downstream O2 sensor.


Downstream O2 sensor is after (downstream) the catalitic converter on the exhaust pipe. Upstream O2 sensor is after (downstream) the engine exhaust manifold - before (upstream) the catalitic converter. Upstream O2 sensor controls air-to-fuel ratio to yield a small excess oxygen. Downstream O2 sensor assesses the catalitic converter performance.
