Hi Subaru Fans,

I am new to this group and need help in replacing Oxygen Sensor (Air Fuel Ratio A/F Part # 22641AA280 on 2004 Forester 2.5x. I currently have a check engine light with P0032 code and hoping that replacing the above part will fix it.

My question is how difficult is it to change this part, since I've never done this before.
Also is this a DIY, in which case what tools do I need to make the job easy ?

Thanks
-Irfan

I got the O2 socket over the sensor and then the wrench on but it became stuck tight against a sump. Be sure there is room for the socket and wrench, in the end a large spanner on the socket worked better for me. I learnt that disconnecting the battery reduces intermediate trouble codes too.

Update: Replacing O2 sensor (Air Fuel Ratio A/F Part # 22641AA280 on 2004 Forester

UPDATE :
I ordered Subaru OEM sensor Part # 22641AA280 on E-bay for $45/ and got it installed yesterday from an Indy who charged me only $60/ and there is no P0032 code

Happy that my cost to fix the check engine light was only $105 = $45 + $60

For those interested in buying Genuine Subaru parts at a very reasonable price seller's E-bay ID is 'reload796'
