I just ordered the front and rear O2 sensors for my 2001 Forester from my NAPA dealer. The front one did not match up at all. After a while with the NAPA Tech line it was discovered that I have a 2.5 Legacy motor installed and that I need to mention that when ordering any further engine related parts. What gives on this one ??????? SOP for Subaru to do that ??? Nick In New Olreans

Spot on Perfect Thanks for all the help She Purrrrrrrrrrrrrrrrrs like a kitten now

I Just Changed The Tps On My 2001 Forester.first I Disconnected The Battery Then I Changed Out The Tps And Then I Re-connected The Battery. When I Started It Up It Idled Just Fine But My Check Engine Light Came On And My 'at' Light As Well.i Disconnected The Battery For An Hour And Rehooked It Up Only To Have The Same Result. I Then Unplugged The Engine Fuses For 15 Minutes And Put Them Back In Only To Have The Same Result. When I Attempted To Take A Test Ride The Transmission Jerked When Shifting Into Gear(its An Automatic)very Roughly. Dont Know What Else To Do . I Am In Desperate Need Of Immediate Assistance And Help On This One.

Does anyone have a good source for a throttle position sensor for my 2001 Forester ???? My area places dont even know what a Subaru is . Thanks a lot Nick in La.

I have a 2001 Forester too and to get to it you have to go from underneath the front passenger section of the car right underneath the passenger headlight side and it unbolts from there . What is the part number for the front O2 sensor I bekieve I have the wrong one and cant find the correct one. Thanks a lot and hope the info helps you out too. Nick in New Orleans

Does anyone know the correct part number for the front O2 sensor on a 2001 Forester S Automatic ??? Apparently I received the wrong one however the back one was spot on. Can you also recommend a good source to buy these parts form. Thanks a lot Nick in New Orleans

New O2 sensors just came in today - both front and back . I will replace them Monday and hope that will make a difference . I will keep everyone posted on the progress .

I doubled checked everything and discovered that the bottom lip to the air filter housing (with a K & N in it) was not seated properly . I have adjusted it properly and will see if that was the culprit. My forester is an automatic and the low mileage just reently surfaced. I will replace the front O2 sensor as well so keep your fingers crossed. Thanks for all the info Nick

Hi All New member to this site I have a 2001 Forester S w/58,000 miles. I recently did a complete tune-up with new Iridium spark plugs,PCV valve,Fuel Filter,K&N drop in air filter,and all fluids were changed to synthetic. Tires are inflated properly and no pulling either.I commute 90 miles a day at 65mph maintained for the most part and right now I am not using A/C. With all that I am only averaging 24 MPG ( . Any one have any ideas to improve this mileage ??? I thought I would be getting close to 30 mpg Your help will be greatly appreciated Nick in New Orleans
