I have a 2001 Acura MDX with113,000 plus miles. It is an automatic. It is a water cooled 4 stroke SOHC 6-cylinder V6 gasoline engine. The malfunction indicator light came on. I checked the gas cap and it was tight. We have trouble codes 1740 and 1456. What could be causing our problem? Is this something we can fix ourselves or do we need to take it to a dealer? Thank you for your help
