I just did a word search of the shop manual and found nothing related to a high temperature shutdown. Pgs 7-29 through 7-31 have the ECU diagnostic codes, none of them are for high engine temperature. Code 70 is given when the engine is idled for more than 20 minutes. The ECU shuts down the engine to prevent overheating, but that's the closest thing I can find to an oil temp shutdown.
