Hi Im David, thanks for visiting the site. what was the code that was obtained when you took it to have scanned?

Customer: replied 10 months ago.
P0420 Catalyst Efficiency Below Normal (Bank 1)
Expert:  david craig replied 10 months ago.

Ok. thats the bank 1 sensor 2 (rear)oxygen sensor reporting whats coming out of the catalytic converter to the computer. replacing the sensor is a 50/50 shot. you will need to determine if the cat is clogged/bad. to do that requires a back pressure test or a temperature comparison test.

Customer: replied 10 months ago.
I only have 61k miles on this carWould that be a variable in the cat getting clogged or going bad?
Expert:  david craig replied 10 months ago.

yes it would be. it doesnt matter how many miles are on your vehicle. you dont want to start throwing parts at your car until the root of the problem is found. have the tests done.
