Hello, my name is***** will assist you.
There are fa few causes for the solid tone on your engine. Overheat, loss of oil pressure and battery overcharge. You will need to test each one locally on the engine to locate the cause. If it is not one of these 3, the engine will need to be hooked to a scanner to discover what is causing it.
Unless you actually test these items, you will not be able to locate the cause. That or take it to the dealer and have them scan the engine. There is no magic dart that I can throw to tell you exactly where the issue lies. I can only tell you how to go about finding the problem.
