This trouble code came through my code scanner and I wanted to know what the possible causes and solutions for this problem would be.

My signature has a link to a manual the will give the possible causes and procedures. I would start by checking for an air leak in the snorkel and checking the intake manifold. You can spray some carb cleaner around it and listen for an idle change as you spray.
