P1345 SES fault

[ChevyBoy44]

Hey, a couple of days ago my truck decided to throw the P1345 code. I bought a scanner and it tells me that its a camshaft to crankshaft correlation fault. The truck is a 1997 K2500 with the L29, Vortec 454. There is no visible change in idle or performance and the truck seems to run and drive fine. I was hoping someone would have some idea as to where i should start with this issue. I did try to clear the fault and the SES light just turned back on after a couple minutes.

i would start by changing the camshaft position sensor i believe its no more than $40.
