Thanks Psycho, I came to the same conclusion last night after looking
some more and reading the manual more carefully.

I had already checked that temp sensor and it was reading the proper
resistance for a cold engine.

What exactly is the car doing? Does it not start at all or does it run
very rough until it warms up?

Something suspicious that I found though is that the electrical
connector for the throttle position switch was wet, and this fluid
seems to have gotten inside the connector. I cleaned things up
reasonably well but didn't get everything back together to try
starting it yet, as I had the air filter / air meter removed for
inspection. Throttle switch checked out okay but the contacts may
have been shorted out with that fluid.

The throttle position switch only reads two positions, fully closed
and fully opened. Make sure when you reinstall it that it's adjusted
properly. That may well cause start/idle issues. I doubt that the
contacts are shorted out, my sons car blew a power steering hose and
completely saturated everything under the hood and didn't mess
anything up. Drop all the information here that you can and we'll see
what we can collectively figure out. Have you checked the condition of
the cap and rotor as well as the timing belt?
