If the car is a 2000 it has the 3.5 LX5 shortstar engine... which does not have intake gaskets that would leak due to GM dexcool coolant eating them away. Coolant does NOT flow through the intake on this engine (only place is through the throttle body), there is a crossover tube on the drive side of the engine that the water flows through instead of the intake. You can usually take that sensor and clean it off/polish it with a brass brush or steel wool. It has a steel clip on it.
