This code is an indication that the synchronization between the Crankshaft and Camshaft is off.
Can be caused by a bad crank position sensor or bad cam position sensor or worn (stretched) timing set. The MOST COMMON cause of this in chevy engines is a worn distributor drive gear.

If you can determine the ignition system is ok, I would look at fuel pressure and the fuel filter. If the distributor was loose you may have to check base timing.

1999 GMC suburban is markin PO 1345 code.


That is a cam to crank position correlation code. I understand you can adjust it by turning the distributor until the value is right. You need a scan tool to see the value and check it each time you adjust the distributor.

GM OBD2 code 1345 causes


either the crankshaft sensor needs to be changed or camshaft sensor.Both work together and are under that code.If you change the sensors you will need a crankshaft profile correction.This should be done by your dealer with the proper scan tool.

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

My mechanic done a egine swap for me on my 98 tahoe and he can not get the timming right one the new motor it keeps giving him the 1345 code how can i help him?


The 1345 code is either the crankshaft or camshaft position sensor, better to change both of them if the car has both, then you won't have to worry about the other one going bad later.
Also the computor should be reprogrammed for the new engine.
