Google "Temperature Sensor NTC M12" and open the first .pdf from Bosch.

I believe the same thermistor is used in a long range of senders.

The chart from Bosch .pdf nicely complies with the info you'll find if you google
0065427717 ohm . Or here http://www.peachparts.com/shopforum/sl-forum/246885-560sl-temperature-sensor-test.html

I wouldn't trust that data unless its the exact part. I've tested many thermistors (not the one OP posted) recently for a Megasquirt conversion and they give different resistance curves than the one in the PDF you mention.
