I have inherited a truck when i got married from my father-in-law it is a 2003 V6 3.7 RAM and we have changed the engine about a year ago...with a brand new one,,,and it is throwing me a camshaft position sensor code...but i put new one in...and it is still giving me the same code!!...it eventually starts but it takes maybe 10 minutes sometimes to start!!!...i think it maybe the wiring harness....
