Does a 92 model jeep 4.0L have camshaft positioning sensor?

No, the 1992 Jeep 4.0L engine does not have a camshaft position sensor (CMP sensor) in the same way later models do. The 1992 model uses a distributor which incorporates the functionality of a camshaft position sensor indirectly. The distributor's rotor position relative to the crankshaft position sensor provides the information needed for ignition timing and other engine functions.
