To be more precise, you'll need to access it from the top of the engine, likely requiring removal of some components like the serpentine belt and possibly some engine covers. It's usually mounted on the cylinder head, close to the camshaft sprocket.
Because of its location and the need for potential disassembly, you should consult a repair manual specific to your Jeep Liberty's year and engine. A repair manual will give you precise diagrams and instructions to avoid damaging other engine components during the process. Improper removal can lead to further issues.
Instead of trying to locate it yourself without the proper resources, consider taking it to a mechanic if you suspect a problem with the CMP sensor.
