Same O2 sensor in 2.5 as in 2.2?

[Guest jclay]

Hi All,

 

I know it's a long shot, but my 02 2.5 OBW is throwing a code and telling me it needs an O2 sensor...I happen to have one laying around that I bought for my former 97 legacy wagon with the 2.2...any chance they are one in the same?

 

Any thoughts on how I would find this out? What I have is OEM from the dealer, part number 22690AA290...

 

Please advise, thanks!

if it were a 97 , not an 02, the answer would be yes, the same . (except maybe for the connector.) but 02....?????

 

i would pull the bad one and look at it. there is a pretty good chance that the connector is different. but there is a small chance the part number on the o2 sensor itself is the same. that's what they did going from 95 to 97.

 

as a matter of fact, the front and rear have different part numbers in 97 but the sensor is the same, just the connector is different.

ebay, and any number of dozens of online retailers list part numbers. a quick glance there gives you an initial chance of interchangability.

 

subaru has it's own parts website called opposed forces, with part numbers as well.

+1 on what gary said!

 

for 2002 P/N is 22791AA00A (assuming you need a front O2 sensor)

for 1997 P/N is 22690AA290

I have no idea what the difference is

when searching on line for replacement o2 sensors, (i was just looking at price and availability, i wasn't really going to buy an after market part) i noticed that one, at least one, of the ''generic'' o2 sensors, without a connector, was listed as fitting 1990 - 2011.

 

now, i didn't bother to study the info or even to determine if it was front or rear, but there is a chance .....

 

so good luck.
