Dear Scotty. I have a 2017 Honda Ridgeline AWD 3.5L Automatic Transmission with 89,000 miles on it. It has a P0430 code “Front Bank Catalyst System below threshold bank 2”. But, this code comes and goes. I drive around town in Oregon and it usually comes on and stays on. But if I drive the truck on the freeway for about an 35 - 45 minutes it goes away for about a week. What is going on? Do I have an actual problem or a hypochondriac computer glitch?
Thanks for any help you can give.
Daniel H.
More often than not your catalytic converter is a little bit worn you might try some catalytic converter cleaner before in a gas tank and one tank of shell super unleaded gas which can often make it burn the impurities out
With that mileage, you should not have that code. I would check the engine performance first.
