If I replace the camshaft sensor will it help with my compression?

Hello,

Unfortunately, no , it will not. Low compression is from either worn piston ring, worn valves, blown head gasket, or a cracked cylinder head or engine block. Those are the only things that will cause low compression. Basically, low compression means tearing into the engine and doing mechanical parts replacement. I have included a few links below for you to go to below;;

Please go through these guides and get back to us with what you decide to do. If you want to fix whatever it is causing this condition, we can help you that as well.

Thanks,
