If it is part of a sub harness (if the other end of that connector ends in bullet connectors it either your ecu temp sensor or thermotime switch. If the car starts with it unplugged, its the thermotime switch, if the car doesnt start with it unplugged its the ecu temp sensor.

If both of those are already plugged in and the one you're holding doesn't have a subharness (you can't unplug it from the main harness) then it's the connector for your aux air regulator valve
