I have an 02 3.7l and ir died recently and the codes came up p0320 replaced the crankshaft postioning sencor and then it ran fine for about ten milles and died again now it reads p0725 anybody know what this means and it also developed a mist out the pipe. I also changed the spark plugs. any ideas.

 

p0725 is "Engine speed sensor circuit"

 

thanks but would this make the truck not run and develop the slight mist

 

Try posting in the 3rd gen. forum maybe they can help more. Did you gap your plugs?

 

that sucks...reset the damn computer...it may be a problem with your jet chip...cause i sure as hell had a crazy check engine light problem.
