SOURCE: I have A 1999 Chevy Tahoe I'm getting an error code P1345

P1345 is cam shaft to crankshaft out of sync.Timing is off on the chain,but not by much,or it wouldn`t run.Oil pressure is low maybe because the oil pump is binding (tight)and making the cam drag(the oil pump shaft is driven off the cam),I would pull the oil pan ,and remove the oil pump and try and turn it to see if that is the problem..If it is ,replace it with a high volume so you know the oil pressure is gonna be good.Also check the oil sending unit before you do this so to see if it is the cause for the low oil pressure reading.If the oil pump is tight to turn,then this would cause the code,and there would be no reason to replace the timing chain.But if the oil pump is not hard to turn by hand ,then the timing chain and gears are to be changed,this would cause the code.If I can help,let me know.I will try to do my best to help.

I have the same year truck as you do. Replaced engine last year and now this same exact thing is going on. I've talked to several people with the same problem. They have said to check the distributor and see if the bushing is worn out. This will cause the reluctor wheel to hit or miss the CAM sensor. Causing the sensor not to get the correct reading. So I took my truck to a very reputable garage, sure enough 12% difference between the CAM and CRANK sensors. Now if the distributor needs a new bushing or replaced a Automotive shop has to "relearn" the the system. After you replace either one. So that they are working together.

1345 is cam and crank sensor correlation its mainly the cam sensor going out, also the delay start that also trigger a camsensor code they call it excessive crank time check the fuel pressure that is capable of setting a cam code (1345) If fuel pressure is good (55-60 psi) expect to replace the camsensor you might as well do the crank sensor heres a nightmare on this code it can set if the distributor is off one tooth and yes these distributor have high failure rate
