Clearly the truck is able to be operated as this is not a code that will render the truck inoperable but it should be addressed. Not only will the truck run properly but you may be able to get a little better fuel mileage.
I attached the testing that we need to do in order to figure out what the issue is. Let's run through this and let us know if you have questions. Thanks
