Hello Driller and welcome to Just answer.com, Super mechanic here. I would guess that the sensors that were checked are the TPS, MAP and ECT. There is a rariance in the engine coolant temperature sensor, (ECT) pertaining to the temkperature of it as to the resistance in it.

The best way to tell would be to install a new one for about $12. There is also an intake air temp sensor that normally won't set a trouble code, they are more like $15

Of course, you want to make sure that the cooling system is full and the engine is reaching the proper temperature before you replace these parts. Let me know, thanks
