Do you have any suggestions ?
Just because you don't believe something does not necessarily mean that it is not true.

My suggestion: As long as it seems to be running OK, just drive it.
Stubbornly insisting that this needs to be fixed when it really is NOT a problem is just not wise.

IF the light comes on more often or stays on, get the codes scanned again.
You might need to do the scan while the light is ON.
Some codes go away when the light goes out.

Just out of curiosity, how many miles on this vehicle ?
