Had p1345 code twice on code reader. Changed out crankshaft sensor. Still rough idle and showing only one p1345now. Changed out cam shaft sensor. Running rougher now and showing p1345 twice. My oil was very low for awhile. I changed my oil two weeks ago the problem started 1 week ago. Could affect anything or could the cam sensor I bought be bad thank you

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.
