To be absolutely certain, you'll need to:
* Consult your vehicle's repair manual: This is the most accurate source. The manual will have diagrams showing the exact location.
* Use a repair database (like AllDataDIY or Mitchell 1): These databases provide detailed information for specific years and models.
* Search online for "[Your Monte Carlo's Year and Engine] Camshaft Position Sensor Location": Images from other Monte Carlo owners who have done repairs might help.
Do not rely solely on general descriptions. The location can vary slightly, even within the same model year, due to engine variations or manufacturing differences.
