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.

P1345 is "Crankshaft position sensor / Camshaft position sensor correlation"

Code P1345 determines if the distributor is installed incorrectly, or if a mechanical malfunction is present in the engine. The light will trigger when the engine is running and the camshaft sensor reference pulse is not detected at a correct relative position with the crankshaft pulse. Most likely causes for this Chevy check engine light code include a faulty crankshaft position sensor, a wiring concern or an improperly installed distributor. A quick check on the crankshaft sensor is to monitor the RPM value with a scan tool while revving up the engine. If the reading is close to twice the expected RPM, then the sensor is likely faulty. There are other less likely concerns possible, such as base engine or computer related issues, but these involve more in depth testing. I hope this information is useful.
