The oil pressure sensor on a 1990 Ford Bronco II 2.9L V6 is typically located on the driver's side of the engine block, near the oil filter. However, the exact location can vary slightly depending on the specific engine configuration. You'll likely find it on the block itself, and it's usually a relatively small sensor with one or two wires connected to it.
To be certain, consult a repair manual specific to your 1990 Ford Bronco II 2.9L V6. A Chilton's or Haynes manual will have diagrams showing the exact location and even pictures. You can also often find these diagrams online through forums dedicated to Ford Broncos or by searching for a 1990 Bronco II 2.9L engine diagram.
