Thanks for the info. I do remember seeing the test of the coolant temp sensor. Here's the info off of AutoZone's website.

So is the stock thermostat around 194 deg F ... which is the hot test point shown in the manual.
According the the on-line manual, there are two separate temp sensors ... one for the the ECU and one for the gage. See Figure 3 quote:
"The engine coolant temperature sensor (1) and coolant temperature gauge sender (2) are located on the side of the cylinder head, under the intake manifold The coolant temperature sensor is located directly under the fuel pressure regulator."
