This is some very good info, especially the coolant sensor is a very interesting read with the step in the voltage. I think this is worth keeping as it shows the voltages one would expect to see when checking the sensor if you fuel consumption is up and you suspect the temp sensor.

Youv'e had a barry with the cas link, i've reposted here but you may wanna fix it up.

I'll add these too as i think there worth a read

Interesting, but not really useful to the majority of home mechanics.

easy. run the car to operating temp then burn yourself taking the plug off.
use a multi meter to test the resistance and then you know if it is reading about right.
Mine was 221 ohms after driving.
