My Coolant temp sensor is off a little...at 90 degrees it Ohms out at 393. I believe target is 200 to 300 at that temp. Thats what I get for buying ebay no name sensors. New Bosch 02 sensor, new throttle plate and new fuel / air plate with potentiometer pre adjusted. Im going to test the pot switch just to make sure tomorrow. Loaner temp sensor, fuel pressure regulator and cold start valve on Friday.
I believe these are the correct ohms for the coolant temp sensor:
60c - 600
70c - 435
80c - 325
90c - 247 etc
Like I said mine is at 393.
