cookie Posted March 22, 2004 Share Posted March 22, 2004 Before I reinstall any thing electrical I like to get a good connection, especially (shudder) in a car that runs in an environment with road salt. Quote Link to comment Share on other sites More sharing options...
99obw Posted March 22, 2004 Share Posted March 22, 2004 Yep, anytime I have a connector apart I put some dielectric grease in it before I put it back together. The salt situation in PA is much better than NY. I am not sure they even use salt in the northern portions of the state that I visit.

subeman90 Posted March 23, 2004 Share Posted March 23, 2004 Correction: 4. screw in NEW one OOPS!!!! my bad.. you guys try getting all technical at 6 somethig in the morning... I think that maybe slight warmth in the exhaust is good but too hot and you can mess up threads on it can't ya???? Correct me if I am wrong....

cookie Posted March 23, 2004 Share Posted March 23, 2004 state motto is add more salt, the tool of choice was frequently the hot wrench. After I got here in Ca I was frequently assigned to be the guy with the torch due to my experience with corrosion. You can get out 30 year old salty exhaust studs by cherrying them with a torch and useing care. So I would say no to that. Heat can often save something that a tanker full of penetrating oil cannot. By the way once you get that rusty bolt out put a new one in. Or in this case new sensor Quote Link to comment Share on other sites More sharing options...
howards11 Posted March 25, 2004 Author Share Posted March 25, 2004 I ordered both sensors (front and rear) from: http://www.autopartsauthority.com They are Bosch brand and I had them shipped next day. My local sources (Pep Boys & Auto Zone) did not have them in stock. The counterman at Pep Boys brought out one that did not even come close to the correct Bosch numbers. It would be nice for Pep Boys to hire people who UNDERSTAND English (editorial comment). My mechanic will be installing them on Monday. Thanks to everyone for their help. ~Howard Quote Link to comment Share on other sites More sharing options...
howards11 Posted March 29, 2004 Author Share Posted March 29, 2004 The saga continues....... My mechanic just called with interesting news. The Bosch web site as well as the vendor's web site (http://www.autopartsauthority.com) have the incorrect part numbers listed for O2 sensors. My kind of luck ! My guy is going to try and get the front sensor from Subaru. I have to get an RMA from the vendor. It's going to be interesting trying to explain this one. ~Howard Quote Link to comment Share on other sites More sharing options...
friendly_jacek Posted March 29, 2004 Share Posted March 29, 2004 No way! Are you sure? I just ordered the same sensor (Part #: 17018) for my 2000 Legacy after checking Bosch website. What is then the correct part #? Thanks, Jacek Quote Link to comment Share on other sites More sharing options...
howards11 Posted March 30, 2004 Author Share Posted March 30, 2004 JACEK: The Bosch site and the autopartsauthority.com site show #13036 for the REAR O2 sensor and #13469 for the FRONT O2 sensor for the 2000 Forester. My mechanic said both are incorrect. In fact the cables were not long enough and have different type connectors. ~Howard No way! Are you sure? I just ordered the same sensor (Part #: 17018) for my 2000 Legacy after checking Bosch website.What is then the correct part #?

friendly_jacek Posted March 30, 2004 Share Posted March 30, 2004 You are right, autoparts lists Bosch #13469 as front O2 sensor for forester but #17018 for legacy and outback. What a screwup! I will have a delivery tomorow so I will know if this is correct or not by the end of the week. I also noticed from this publication: http://www.endwrench.com/pdf/fuel/FtFuelEmmisionW00.pdf that the front oxygen sensor is acctually not a typical oxygen sensor but an Air-Fuel Ratio sensor. Does anyone understand what the real difference is? Quote Link to comment Share on other sites More sharing options...
howards11 Posted April 5, 2004 Author Share Posted April 5, 2004 After the tune-up, new air filter, new gas filter, new PCV valve, 4 wheel alignment and a new front O2 sensor my MPG has gone from 14 MPG to a bit over 16 MPG. All measurements are city driving. ~Howard Quote Link to comment Share on other sites More sharing options...
friendly_jacek Posted April 5, 2004 Share Posted April 5, 2004 Do an OBD2 scan and see if the TPS is functioning correctly. In my 2000 legacy, I got 16 MPG (city) for a year before a code for TPS showed up. New TPS and $330 later, MPG is 19 city/24 hwy. BTW, Bosch #17018 ($156) is OE part for legacy and outback, I confirmed. Quote Link to comment Share on other sites More sharing options...
howards11 Posted April 5, 2004 Author Share Posted April 5, 2004 You have to help me with this one. What is the TPS ? Wouldn't it show up as a CEL if it wasn't functioning correctly ? Should I expect more MPG from the Forester ? Remember I think I'm still using that special winter fuel. My mechanic charges $70 fee for the diagnostic test. ~Howard Do an OBD2 scan and see if the TPS is functioning correctly.

cookie Posted April 5, 2004 Share Posted April 5, 2004 I think you should do a bit better too.My forester always seems to turn in around 25 with one rare tank at 17 and another at 30 that I may never duplicate again. Math error or an egg under the pedal that week. Quote Link to comment Share on other sites More sharing options...
friendly_jacek Posted April 6, 2004 Share Posted April 6, 2004 RE: "My mechanic charges $70 fee for the diagnostic test." $70 is almost enough to purchase your own OBD2 interface to your laptop or pilot and read codes + sensor status for free. Like I said, it took a year for the TPS problem to declare itself by CEL in my case. However, I had planty of warning signs: poor mileage, fuel in oil, hesitations, poor AT shifts. The Subaru dealership could not "duplicate the problem" before the engine light showed up, typical for dealership mechanics these days. If you have similar problems, look into TPS, but it might be a long shot. Unfortunately, many things may produce poor mileage. Quote Link to comment Share on other sites More sharing options...
howards11 Posted April 6, 2004 Author Share Posted April 6, 2004 I not having any of these problems. It runs great since the tune-up. I love the Forester but the MPG is still the issue. I am going to wait a bit on this one. I might throw a bottle of fuel injector cleaner into the tank. ~Howard :-\ RE: "My mechanic charges $70 fee for the diagnostic test." $70 is almost enough to purchase your own OBD2 interface to your laptop or pilot and read codes + sensor status for free.
