Wierd. SES light came on so I pulled it. Code number I can't recal, but it said thermostat failure. No overheating or anything bad. I bought a new one and some more dexcool to swap out thursday. Anyone have any related issues?
One of these two could come up with one that is stuck open.

DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
