Hey, I finally got around to scanning my new used Olds Cutlass, and it's throwing whatever the code # is for Coolant Temp Sensor open... the ECM is seeing a constant -36 *F, so there's obviously something wrong.

I bought a new CTS, but I've got a problem... I can't FIND the thing on the motor! Where is it, under the distributor or something???
 
I don't have a 2-barrel intake, but if it's like the others it should be very near the thermostat housing. Likely coming right out of the front edge of the intake or on the housing's "hump". There will be two temp probes, a sensor for the ECM and a switch/sensor for the instrument panel light/gauge.

Hope this helps.
