Preparing for my State emission test, my OBD-2 code reader is picking up a P1519 code.

Car is a Renntech E60RS, with a M119 engine, based on an E420. I think that refers to the valve adjustment, however I read somewhere it may be coil related, but my car has the coil on plug setup.

Car has 60,000 miles, runs great.

Any thoughts?

Thanks
