To be absolutely certain, you should:
* Consult your vehicle's repair manual: This will have diagrams and precise locations.
* Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to search by your vehicle's year, make, and model to view diagrams showing the sensor's location.
Looking at a diagram is strongly recommended before attempting any repair or replacement. The area around the camshaft can be complicated.
