Anyone who can supply with some ohm data for me? Sensor is 0280130044/0065427717 i need someone to measure when engine is 40/80degrees celsius. Would be great help for me, thanks! Same sensor in W124/W126/C126/R107

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.

If the OP googles 073-121-31 mercedes pdf he'll find the attached .pdf with MB factory values(which are the same).

Iam asking to measure on car, using temp instrument as reference. I know about what they are supposed to be, but what are they really?

I found out about this, thanks for help!
