I checked the ohm on the top sensor and when I pulled the plug off the fan kicked in and the motor went into a safety mode. I checked the sensor with a ohm meter and got a reading from 34.7 when the motor was cold down to 10.3 when the motor was warm. Trying to find out where it should read but can't find anything. The lower sensor which is supposed to send the info to the gauge only showed one reading with the ohm meter and that was 24.8 and never moved. So does anyone know what all of this means? I am asuming that sense the temp sensor for the gauge didn't change thats why the gauge doesn't show any temp. Does this sensor control the fan? I think I might replace the relay under the hood for the fan in the underhood fusebox too and see if that fixes it. I just want to make sure the car will not over heat on me when I go down the road and the only way I know to keep an eye on it is to use the temp gauge.
