I have a high milage great running 99 s10- 4.3L V6. i've replaced the cam & crank sensores, did major tuneup.cleared coad several times and it still shows 1345 coad and wont pass inspection. i've replaced the pcm with 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 drive my 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.
