Everyone remember how my Engine Temperature Sensor never went above 125*F? Well, Padgett directed me to this green wire right under the TB. I saw it, but could never get in there, until now! I have the throttle/TV cable assembly removed, and now have clear access to this sucker. There are two things, one which I think is the actual temp sensor, which has a connector, versus just one wire. Then directly below it, is a little green wire, which seems to connect to something, but i'm not sure what. Well, the larger connector was just fine in terms of it'* contacts, however, the little green wire wasn't properly sealed, and 16 years of grease, grime, oil, and just all around crap got on it, and it was completly covered in the stuff. I am surprised it actually worked! So, I cleaned it up, and connected everything back up, turned the ignition on, and noticed the temp moved about 10*F from where it was before I started. Mind you, I have not tested this.. and I do not know for certain that this fixed it, I cannot drive the car, I cannot start the car.. she'* immobilized so I can't test it [otherwise i would have]. So, for all of you LN3 owners out there that has a malfunctioning temp readout, hop to this! I would have taken pics, but my mom is in Chicago for the weekend, and has the camera. I can take some sometime this week or next weekend if you want them, that badly.

The coolant temperature sensor is located under the idle air controller (four wire connector). It may have a single blade connection or a two wire connector. The sense wire is green or yellow and if there is a second wire it will be black and go to ground.

I think mine'* a three wire.. but nonetheless, I know what you are talking about. Once I get the TB off, i'll be able to remove this suckers for cleaning and inspection. I'm curious what just one wire can transmit. Oh well, I shall find out!

Single wire sensors use the chassis or the block for a ground return. Bad grounds can foul up all sorts of things.

I concur. I found this out the hard way.. and many times at that.

how'd you get the tB off? i remember a thread where you were out of ideas! was there a bolt left on or something you dont want to admit ?

Still haven't gotton it off. That damn tube is still stuck! I have a 3100 expert comming over tomorrow, and we are going to finish off the disassembly. I have everything off, EXCEPT the TB. Once I get that off, the intake will magically come right out, and hopefully the heads too. I can't find my camera, but if I don't get that damn TB off tomorrow, then i'm definatly going to make a point to find it. I'm pretty sure she and I can figure out the damn thing..
