Another fail
Okay, well I got my car running finally if you did not know. It was a bad CAS sensor, but now the water temp gauge on the dash goes straight to H as soon as I turn the car on. My fans still kick on, and my AEM is showing correct temp 176 full warm. What the hell could this be?

No there are 2 sensors, one is a single wire sender in the back of the head which feeds the dash.
There is another 2 wire sensor in the back of the head which feeds the ECU.

On the 1.6L isn't the single wire sensor in the front thermostat housing?
I've long since moved mine around with reroutes and forget, but that should be the one that feeds the gauge.
You can definitely search though, there have been threads on it.
Richy is correct in that the two wire that original resided in the back of the head feeds your ECU.
The 1wire sensors are cheap and easy to replace, and the wiring...err...kinda simple.

If you are running an MS, you don't use that one wire sensor, which I believe is what switches on the fan at a certain temperature. You can vary the temperature at which the fans kick on, therefore it requires a variable sensor, so it uses the rear sensor.
Edit: uh...same for AEM I think.

AFAIK the 1.6 still has a tiny 1 wire sensor in the back of the head for the dash signal.
EDIT: Just checked the wiring diagrams, I'm right, the 1.6 has in effect 3 water temp sensors, the one that feeds your dash has a black/blue wire colour, likely after all this time it'll mostly look black, but look for something like that around the back of the head and you'll find your sensor
(Fig3 for the thermoswitch and Fig4 for the dash signal)

Figured it out, I broke off the little metal piece that goes the plug slides into. I googled but found nothing, does anyone know the name or product number for this part. It looks like I will have to replace it.
