P0404 has come up three times in the last 10 months and has been reset in all cases. Once in Sept of 2019 and twice this past week. When should I become concerned with this code and what would be the best solution to take if the vehicle needs to be worked on. Thanks, Jim Felland

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
