Location of oil pressure sending unit on a Saturn 1997 with SC2 engine?

The oil pressure sending unit on a 1997 Saturn SC2 with the 1.9L Ecotec engine is typically located on the driver's side (left side) of the engine block, near the oil filter. It's a relatively small sensor, usually with a single wire connected to it.

However, the exact location can vary slightly depending on specific engine variations or modifications. It's best to consult a repair manual specific to your 1997 Saturn SC2 with the SC2 engine (often referred to as a 1.9L Ecotec) for a precise diagram. A visual inspection, once you're comfortable working around the engine bay, is also recommended. Remember to turn off the engine and allow it to cool completely before attempting any inspection or repair.
