I've found an oil temp sensor but only have the RESISTANCE with the relevant Celsius...
for example...
20 deg C = 2.115 K ohm..
30 deg C = 1.375
40 deg C = 0.915
50 deg C = 0.621
60 deg C = 0.430
70 deg C = 0.303
80 deg C = 0.218
90 deg C = 0.159
100 deg C = 0.117
110 deg C = 0.088
120 deg C = 0.067
130 deg C = 0.051
140 deg C = 0.040
150 deg C = 0.031
Also...
it does say on the sheet R25 = 1.7 K ohm
Please help...
Oil temp sensor...

Hello,
V = (R1 / (R1+R2)) * V
R1 = Sensor resistance
R2 = Pull up resistor value
V = Supply voltage (Must be regulated (fixed) voltage. All units have 5v reference out
Pull up resistor value need to be similar to the resistance value of the sensor. I recommend in this case 1K. This is because the 2 resistances divide the voltage. So if both resistance is 1k the output would be 2.5v
1/2 = 0.5 * 5 = 2.5v
If you use 10k the voltage change between 20c and 120c will be small and the values will be noisy.
1 side of the pull up resistor needs connecting to 5v and the other to the signal wire.
Kind regards,
