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.

what is 1345?..cam position?

Thanks Streakin, Your the second tech that has brought that up and thats what i'm going to look into.

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.
