The crankshaft position sensor (CKP sensor) on a 1998 Chrysler Concorde is located on the
passenger side of the engine block,
near the bottom of the engine,
behind the oil pan. It's often a small, cylindrical sensor with a single wire connector. Access might require removing some undercarriage shielding or components.
Because of its location, it can be difficult to access. A repair manual or online diagrams specific to your engine (either the 2.7L V6 or the 3.2L V6) will greatly help in pinpointing its exact position. You'll likely need to work from underneath the vehicle.
