Welcome to the forum
when you ask a service related question you really need to include basic information:
Year
Miles
Last service down and date and miles
Other noticed running conditions not normally observed?
DTCs are only a starting point for a qualified or experienced individual to start a tree of service elimination.

How many times have we read and in my case had to service a problem caused by another shop , dealership or DIY damage another part while doing something as simple as an oil and filter service.
