Yes, I had this on my 97 Stratus....could be a couple of things....one, the there may be damage to the wire connector harness going to that sensor. That was the problem with mine. I replaced the cam sensor, crank sensor, coil pack, mas sensor..etc...it ended up being a burnt spot on the wire harness. They said this is a common problem for the stratus/breeze/cirrus/intrepid.....the most it could be is a bad ECM....there is a bad pin on it located half way down the side where the big connector is. It is the silver block with the big wire harness going to it in the engine compartment. Try wiggling that around...the harness area.

SOURCE: where is the crank sensor located on 1999 plymouth
The crankshaft sensor is behind the crankshaft pulley or harmonic balancer. You can access this by pulling off your tire and the inner wheel well. Then use an air impact preferably a 1/2 inch or 3/4 inch impact to loosen the bolt. Next you will need a pulley puller to got it off the sensor is directly behind the pulley make sure you set the sensor to where the old one was set at.
