Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question!My name is ***** ***** I will be assisting you with your question today.
How is the vehicle running? Loss of power or running rough or anything?
These codes are for the bank 1 and bank 2 catalytic converters. The codes mean they are working below efficiency. Since the vehicle isn't showing any signs of a real issue, it might be a good idea to change gas stations. Sometimes the different additives can cause the codes to appear even though there is no problem.
Clear them and try a different gas station.
Also, give me a couple minutes. Sometimes there are service bulletins for reprogramming the ecm when you get both codes together like this. I want to take a couple minutes and see what I can find for you.
I double checked and there aren't any bulletins for these codes.
It's just not common for both to fail at the same time. One other thing would be the condition of the engine. If it's been a while since it had a tune up, it wouldn't be a bad idea to put a new air filter and set of plugs in it to hopefully solve the issue. If the light continues to come on with these codes, then you are likely going to need new converters.
