Is there a cam sensor in 2002 dodge with 318?

No, a 2002 Dodge with a 318 engine (a small-block Mopar) does not have a camshaft position sensor (CMP sensor) in the same way that many later engines do. These older engines use a distributor with a pickup inside to provide the crankshaft position information the engine control module (ECM) needs for ignition timing and fuel injection. While there's no dedicated cam sensor, the distributor's function inherently incorporates camshaft position information.
