I have included a bevy of information on your vehicle's Camshaft Position Sensors (CMP)(s) in the diagrams down below. I did this because I think the question was how to replace them, but I'm not 100% sure. Any way to replace them you undo the retaining bolt holding them into the cylinder head and pull out. Installation is opposite of removal. Please go through the information provided to you and get back to us with what you find out please.
