I need some help. I recently went for Inspection and Failed with the Trouble Code P1398. All of the research I did pointed to the Crankshaft Position Sensor. So I replaced it. Reset the Check Engine Light with a code scanner and then drove the Truck. a minute or so later the Check Engine Light came back on. I hooked my scanner back up and had the same code again. Is there another procedure that I missed? Is there something else that I need to look at besides the Crankshaft Position Sensor? Should I take the New one back and have it replaced? The engine does run rough and has been suffering from long starts. I don't want to get rid of this truck so I'm trying to do the necessary work to get it back in shape. Thanks in advance for any help. > I need some help. I recently went for Inspection and Failed with the > Trouble Code P1398.

One in the distributor and one on the bellhousing.
