good evening my name is ***** ***** I will assist

the codes are for cat converters. they are worn out and need to be replaced. the precious metals inside are worn out over time and miles.

were there any other codes???

Roy

Customer: replied 3 months ago.
No other codes, but I'm concerned theres a problem that caused the cats wear out so quick considering its a 2010 not older.
Expert:  Roy replied 3 months ago.

how many miles on the car???

Roy

Customer: replied 3 months ago.
70k but not sure if it has been tempered with, couldn't trace its records from CARFAX because its from CANADA not US.
Expert:  Roy replied 3 months ago.

ok, they usually last about 100k. hard to say without any history on the car but the fact remains that they need to be replaced.

Roy

Customer: replied 3 months ago.
can they also cause poor gas mileage like 12mpg
Expert:  Roy replied 3 months ago.

no, if they were clogged, you would have other complaints.

it could be ignition, timing, injectors among the many possibilities

Roy

Customer: replied 3 months ago.
I'm thinking that if i just replaced the cats,they will eventually go bad, if causative problem is not identified. The car starts and drives normal though, No other codes from obd2 apart from 420 and 430
Expert:  Roy replied 3 months ago.

if there are no other codes, then the cats are just worn out
