Wiring help needed. 1993 trionic engine sensor

Should the coolant temp sensor have one lead grounded on a 93 CSET with trionic? One side goes to the trionic 70 pin connector at pin 17. THe other side is continuous to nowhere (not ground or any other pin).
All the schematics I've seen on the other models have one side grounded.
I've tried 3 different sensors, and jumped the one side to ground (which worked for a short while), but now, every hard start triggers 4 flashes error code. It only starts with some throttle, which I understand is the problem with a faulty coolant temp sensor.
Help will be appreciated...
