97 ZJ coolant sensor resistance

(1/1)

SteveTheFolkie:
Anyone know what the resistance should be for a properly operating coolant level switch on a '97 ZJ?  If I leave it plugged in I get an occasional "coolant sensor bad" message; if I disconnect it the message is constant; if I jumper the plug (complete the circuit) I get a constant "coolant level low" - obviously the correct resistance is somewhere between zero and infinity.
I check my underhood fluids every time I fill up (habit my father instilled in me 50+ years ago) - if I knew what resistance was "normal and correct" I'd just buy a resistor and put it in the circuit, abandoning the switch.
thanks much
