    I guess people don't read entire threads any longer. I posted a crap load of information and pics as I went down this road myself. After everything I did I haven't had an alarm in months...The "fixes" are in this thread it just requires some light reading.

    Just Curious if people have to continually "clean" up the chassis ground under the hood support? have followed all the directions with clean and adding a star washer and i still have to pull it it off and take a wire brush to it ever couple months.

    After I added the ground straight off the sensor I haven't. Also I added the Racetronix hot wire kit and opted for the extra ground strap. That sure doesn't hurt and might be something easy to consider for those with alarm issues. (Its just a 12" 8 gauge wire off the battery to the strut tower bolt)

    I actually have added an extra ground wire directly off the oil temp sensor and it worked for awhile, but doesn't anymore. i might add an additional ground from the negative terminal like you are suggesting

    I have done mine twice. The second time I broke out the drill powered wire brush and did away the the paint underneath the grounding washer.

    I have noticed that grounds in general do accumulate oxidation on the grounding-washer flats over time. This could probably be held in check with an outside coating of something like grease or one of those spray coatings.

    Yeah I think pre-ground strap my alarm portion was in check. However the gauge wasn't completely accurate. Now the temps get up to around 210* and seem to hold more when windows/sunroof etc are being operated. Sure can't hurt for how easy it is!

    One connection I redid as they are all pretty lame.
    is this from the top view or from the bottom view?

    If you've done everything in this thread then I would say replace the sensor. More than likely though not everyone of the grounds were cleaned and the dealer only cheaped out making it seem fixed for a period.

    Do the ground strap from the battery to the chassis. That is the only solution that has worked for me. if that doesn't work, like CancerJCC said, time for a new sensor

    ^^^YES^^^
    Mine started going off like crazy at highway speeds last week. I cleaned the grounds at the rear of both heads and the one by the hood strut. Oil temp has never been steadier since I've owned the car.

    None of the contact points looked bad, but I've found that they need to be cleaned once or twice a year.

    PS you may need to remove the battery to get to the passenger side ground but it's worth the effort.

    It is easy to make one but if you want to just buy it and carry with you to the dealer then here is the one I used: http://www.racetronix.biz/customkititems.asp?kc=BGK-001

    I just purchased this with the Hotwire kit. So you have pics on your ground kit installed?
