Default 99-4.3L v6 coad 1345 cam/crank need help

I have a high milage great running 99 s10- 4.3LV6.i've replaced the cam & crank sensores, did major tuneup.cleared coadseveral times and it still shows 1345 coad and wont pass inspection.i've replaced the pcmwith a matching used one,did'nt help so i put the original one back in.timing is correct and im thinking its a problem with the reluctor ring on the crankshaft in front of the timing gears and behind the timing chain cover.this is just a guess, i need to know how to clear this coad permanatly or fix the problem. i still drivemy truck on a daily basis,any quilifide suggestions would help. if you need more spacifics please contact me thanks.

Have you tried the wiring harness? Electrical codes and faults are hard to trace if a replacement part doesn't do the trick then you have to check the wiring.

Howdy, Argon. A code 1345 cam/crank positioning readout is a bitc.......... it is dealing with a random misfire thruout the drivetrain. Some readouts have stated, A loose sensorconnection and or valve train
problem.Great help the readouts are.
