Default Who has a '99-00 CLT sensor?

I need you to measure resistance across the sensor for me. On these pins, http://users.forthnet.gr/ath/twikicore/dsc00621_1.jpg. I can't get to mine while it's on my car because the damn CAS is in the way and I know a few of you have '99 heads laying on your floor/shelves. Help a guy out. Trying to get my damn CLT readings right.

I do. I remember seeing it somewhere in the garage. Of course that means I have to find it. :gay: I'll look at lunch and post back if somebody doesn't beat me to it.

Well i actually found a resistance curve. I measured the voltage at the harness and I get 2.31volts so now I just need to figure out what temp the sensor it as right now so I can figure the resistance to calculate the stock bias resistor value to get this damn CLT gauge working right. It worked the best with the RX7 values though it was reading 20* too cold. The problem with using reverants values and things like that is it goes from 100* straight to 210 or whatever and the car runs pig rich. Should have it figured out sometime today.

Hey, if you get this, would you mind seeing if you can find it for me. I just want to double check what I have. It appears it might be accurate as of now but I want to be sure. If you happen to just measure the resistance, make sure to do it over those two pins if you can. Thanks buddy.

I'm seeing 2.01 across the two terminals (wires inserted in the harness photo)

Thanks man I appreciate it. If my current values don't work i'll be trying yours to see if that corrects it.

I got it jiving now I believe. So far i'm happy with how it is working. My fans are working like they should. My indicated temp is within a few degrees of what it should be, all is good in that part of the world for now.
Just have to solve my darn resets problem.

In addition just to add to it all. I just went outside, plugged in the laptop and turned the key on. The car has been sitting for atleast 5 hours.
The GM IAT was reading 74*, the coolant was readin 73*. Earlier today, the temp was reading 202* and the fans were on. Then my laptop died but the fans turned off a few seconds after that. I'm assuming the NB fans turn on right around 200* though. Kinda nice when things work.
