Those are both temperature sensors. One is used for the cold start function that fires your 9th injector. The other is for engine coolant temp. I think the cold start one is #4.

#4 would be the sensor for the cold start valve. #5 is the CTS sensor. This sensor tells your ECM what temp your engine is running at. The cold start sensor is not ECM controlled.
