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).

I'm trying to adjust the timing on the subaru 1997 outback legacy 2.5 engine and it seems to not be correct.


The ignition timing is not adjustable. It is computer controlled by the crank sensor, cam sensor and knock sensor. Would be easier to help you if I knew why you were trying to adjust it. Have a great day.
