So i was changing out my negative battery cable today and bumped my hand on the coolant sensor that threads into the intake manifold, and i guess after 15 years the plastic became brittle so it snapped right off. from what i can tell this just sends a signal to my dashboard for my temp reading.

Does anyone know if i can leave it unhooked and still drive the truck until i get a new sensor this weekend? Also, what are my chances of actually being able to unthread the sensor after 15 years?
