Are there one or two coolant sensors? I know there's an oil temp sensor also.
I was told one is for the gauge and one is for the computer.
Is that true and if so where is the second one hiding?

I found one right next to the upper radiator hose that points up. When I disconnect this I can see it on the gauge.

The water temp gauge on a auto is nothing more then a switch. The PCM has no idea what the water temp is.

There is only one sender.

OK - that's what I thought, just wanted to double check.
The ecm uses the oil temp to make changes then.
