A p1345 code indicates a Camshaft To Crankshaft Position Correlation problem. In most instances this can be corrected by adjusting the Cam Retard Offset. For this procedure you will need a scan tool.
1. Install a scanner and look at the cam retard value with the engine at 1200 RPM in park. The factory specification is 0 degrees to -4 degrees. 2. If not in specification, turn the distributor slightly, then bring the engine over 1,200 RPM again and the value should update. Repeat adjustment and raising engine speed to update the number until within range.
