'00 OBW: O2 Sensor, Bank 1 Sensor 2 - Front or Rear?


Recommended Posts

Yes..Your Subaru, as most, have only 1 bank of Oxygen sensors..Bank 1. Sensor 1 in the front, usually right in the Y pipe Cat, Sensor 2 is the rear, usually by the tranny tailshaft. On Newer, some 2003 and up, the rear is in the backside of the same Y pipe Cat.

Thanks... now to find someone who carries 'em. AZ wants way too much ($350 for the front, $150 for the rear), and 1stsubaruparts.com carries only the front from what I saw ($88).

 

Gotta hunt some more...
