I have a brand new oil sensor sitting in my parts stash that I would sell for the same $25.00 plus shipping that I paid for it. It is somewhat of a pain to do as I understand it, but not terribly so. Basically, you need to have a couple days to spare and the proper sealant for the lower oil pan. If you do a search you can find the Loctite number for the sealant, or e-mail Fastlane and I'm sure they it. Drain the oil and let the car sit overnight (oil contamination will make the sealant not hold properly). You have to remove the bolts for the lower oil pan cover and then you need to take a cherry picker/overhead hoist and pull the engine up some (you DON'T have to take anything loose, you are just getting clearance to take the lower pan cover out). The sensor is swapped out, lower pan and the upper pan are cleaned off, sealant applied to make a gasket, bolts installed, oil in, and you're done.
