Default DTC Code P0343

Need some advice..Just did a LS1 to LS2 (stroked to 402) swap on a 1998 coup. All is good but I'm throwing a P0343 code which is my Cam position locater. When I did the swap I bought a new harness to extend it from the front of the engine to the back harness. I am somewhat confused as to what could have went wrong. The car runs great but shows the classic symtoms of the P0343 code ...sometimes takes about five seconds cranking to start while the PCM identifies the exhaust/power stoke through other engine inputs..... Any ideas what I should check first on this?

Appreciate any thoughts......

cam gear bolts loose? could be the cam is walking back/forth.if you have access to a scanner,see if you actually getting a signal and if so is it consistent.

I changed the sensor out and my code went away.
