However, the *exact* location can vary slightly depending on the specific engine (2.4L or 3.1L, for example). To be certain, you should:
* Consult a repair manual: A Haynes or Chilton manual specific to your 1999 Pontiac Grand Am will have diagrams showing the precise location.
* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to enter your vehicle's year, make, and model to see a parts diagram. Look for the camshaft position sensor in the engine diagram.
Without knowing the exact engine type, providing a more precise location is difficult and could lead to incorrect information. Always refer to a reliable source like a repair manual or parts diagram for accurate placement.
