Coolant Temp Sensor Resistance Measurement
Just thought I'd share this. I recently ran into a no start condition, but had spark and fuel. Checked a bunch of stuff with no luck. Found that when I unplugged the coolant temp sensor (on T-stat housing) that the engine (1995 YJ 2.5L) ran fine. I didn't see a resistance range for the sensor on the forum, maybe I didn't search enough? I bought a Haynes manual and it doesn't give the range. I did a little test. At room temperature 73.4 (F) the resistance was 8.82 Kohms at 125.6 (F) (water from coffee pot at work) the resistance was 2.37 Kohms.
