The oil pressure sending unit on a 2.4L Pontiac engine (likely referring to the Ecotec engine family found in various GM vehicles) is typically located on the
passenger side of the engine block, near the oil filter. However, the exact location can vary slightly depending on the specific year and model of the vehicle.
To be certain, you should consult a repair manual specific to your vehicle's year and model. A picture or diagram in the manual will show you the precise location. You can usually find these manuals online or at auto parts stores.
