P1345 code Crankshaft Position-Camshaft Position Correlation. So what happens is the camshaft position oil control actuator goes out or gets plugged up. Here is the location so you can replace the part or clean the screen, also make sure the engine oil is clean and full with a new oil filter. Check out the images (Below). Please let us know if you need anything else to get the problem fixed.
