If you are talking the Benz 4 prong sensor , the values are the same , they are just isolated from one another as they feed different systems.
The resistor in series will not change the cut in. It has to be in parallel. Reason is the total resistance of the sensor will now drop.
[ parallel resistors total value is always less than the smallest resistor]
So, using an ohm meter , measure the resistance of the sensor compared to the gauge at the temp you are looking for and
compare to your chart for the desired ohms.
you are looking for 215 at 93 - correct?

Plug what you have for sensor read at temp and using RT formula for par. resistance, the unknown R can be fiqured..
[ look at google for a par R plug the number data computer"
That makes it easy..
