Assuming you're talking about the engine oil rifle pressure #1 sensor, it's located on the left side of the engine, below the heads. You unplug the electrical connection, then you remove it with a socket... I don't remember off the top of my head if it's 1-1/8" or 1-1/16", but it's an ASE socket larger than one inch. Installation is the opposite of reverse.
