TBH, unless you're planning on modifying it, who cares about the values, readings/resistance, etc. As long as your fans turn on when the temp reaches the specified on value, I believe at 105°C, then you're good to go. Or you can simply get rid of that sensor and swap it for an on/off temp switch which will function the same way, minus having resistors/values to worry about.

thanks for the reply. I am talking about a different coolant temperature sensor. I am talking about the two prong temp sensor which is two sensors in one. One wire goes to the fuel injection control and the other sensor goes to the ignition control.
I care about if it is accurate as if not the ignition and fuel injection control systems will not have accurate inputs and therefore not manage the fuel and ignition systems properly.
You mention the radiator aux fan switch.
yes I will take a couple of more measurements as it warms up to see if the sensor is accurate at higher temperatures.
