Did you remove the distributor to replace the cam sensor? How does the distributor gear look? P1345 means your camshaft sensor is not reading in sync with the crankshaft sensor. Only 3 things can cause that. Improperly timed distributor, worn distributor gear or a worn timing chain. Well I guess a damaged crank reluctor wheel or damaged/sheared crankshaft keyway could too but that would be highly unlikely.

The distributor has to be re-timed with a scan tool. +/- 2° is spec, will not set a code until about 7-8°.

I have a OBDLink MXPro that will do it but had to download and pay a few $ for the Torque Pro app PID to read the CMR. The MX Pro links to my Android phone and I can see the whole datastream with my phone.
