AnswerTry going to the dealership's service department. Most will have what you need on their computers and can print a copy for you. They did it for me in Houston, for the AC system.

The oil pressure sensor, on your 2003 Chevrolet engine, is located on the front of the engine, just above the oil pan. The pressure sensor will have two wires going to it.
