2.5K ohms at 65-70 deg. F
The same temp sensor in my Rock Buggy (1994 1.6L 16v) gave a similar reading so I believe this is a correct value.
I'll check the circuit next week when I get the spare sensors.
Truck got a new owner today even with the CEL and code 15.
I've signed up to replace the temp sensor and look into it further.
