Help Checking CHT Sensor

I have my Bentley and I thought I knew what I was doing but after reading some past posts I may be al screwed up in trying to check my CHT sensor. Here is what i did

1. Made sure car off b/c measuring OHMs

2. Located White sensor amongst 3 sensors in engine bay.

3. When I pulled the sensor apart I have the two pronged CHT sensor. Temp outside was 59 Fahrenheit. Was not sure whether to measure the male or female side of the sensor so I did both. When I measured the female side (wire harness to car) the reading was 1.068.

3. When i measured the male sensor wire self I got 3.002.

What is confusing me is when I read this past post by one of the forum members: "Check your head temp sensor. It's the gang of three electrical connectors on the upper left of your engine, the white connector. When cold it should be around 2500-3500 ohms, when hot around 200-300 ohms."

This is where things stand. First did I do the readings correct. Second does the reading show a good or bad CHT?

Another forum member wrote in another post: "check the wire from the CHT to the DME." Is this what i did by my above testing or is this another test and if so, how?

Thanks everyone
