Would like to see a diagram of where exactly the crank shaft sensor is located in the 2004 hyundai santa fe so that i can change it.

Which engine?? V6 or the 2.4I? The V6 CKP is in the engine block near the flywheel side of the engine (behind and lower right of the exhaust manifold nearest the radiator) A 10mm bolt holds it in place. On the 2.4 4cylinder, the sensor is at the front of the engine behind the Timing Belt cover at the crank shaft. To replace it, you have to remove the timing belt, but you also need to know some technical things to reinstall the belt to be sure you are installing it correctly. Go to http://www.hmaservice.com/ and register. You'll then have access to lots of technical info and manuals, wiring diagrams, etc. about your vehicle.
