How do I use a multi meter to check a sensor? ECT 850

OK...so here's what I did:
Engine cold...85 degrees out all day. The meter set at 2000, the reading was 1740, at 20K 1.75....I let it heat up to operating temp (via the interior gauge): at 2000= 225, at 20K .25 This kinda corresponds to your chart, but not exactly. It did go down!
So, if it's not the sensor, then I guess it's the leads going to the sensor...those barrel connections that I can't get inside of to clean. I used a very small jewlers file to try to rough up the inside of the barrel, but the Code still comes up.
Any ideas?
