I replaced my block and started getting this code. I have replaced the PCM, the camshaft position sensor which is what the code is for with a MOPAR sensor, I have traced the wiring harness, and I have replaced the pigtail but I still get the code. I originally replaced the sensor with one from oreillys and when I would start the truck the code would instantly come on. Now with the MOPAR sensor it is off until I drive it for less than half a mile and then comes on. It won’t go off unless the codes are cleared and while it’s on the truck won’t shift into overdrive. I’m completely out of ideas and need some help.

 

Check the connectors for that sensor at the PCM. Make sure they are clean, and tight.

 

replaced the just block? entire engine? is the cam shaft in the truck the one it had before the swap?
