Hey,
I checked the ohms on 4 different sensors from 70F to about 220F, range was 3000 @ 70, 200 @ 220. The ohms climbed smooth with no spikes. this sensor is the same used on the 7427 and 90's vette. stock form was a 1990 grand am. Yea and sorry I was getting code 14 coolant high not 26 QDM, then today after good and heat soaked I got a code 15 coolant low........ wheres the "slapping my forhead" emoji... Im going over the wiring for the 50th time but after that I guess ill deal with it :)
