Just replaced my cat on an 09 acadia about 5 months ago. Have p2099 and p0420 on now. Going to try changing this downstream sensor and hope the codes go off

[@geebody8969]

[@javierargote]

[@JimmyBoy87]

I have code po420 2010 gmc Acadia truck runs good has all its power I replaced 2 02 sensors so far can it be my converter or just replace those other two sensors?

[@ultimatediyguy395]

More than likely yes, you may need new need a new car. Some people like to try catalytic converter cleaner as a last resort

[@deedaartyst]

niiiiiice info, cooool informative vid

[@sighnotes]

Isn’t there more than 1 O2 sensors?

[@ultimatediyguy395]

Yes on this vehicle there’s 4 of them

[@sighnotes]

@@ultimatediyguy395 I know where 2 are gotta find 2 more now lol

[@Your_Online.M0m]

Are they all the same part number? I am having a terrible time on google determining the correct replacement parts

[@ultimatediyguy395]

The downstream sensors for bank 1 & bank 2 are the same

[@1989hondakid]

Did this fix the issue?

[@ultimatediyguy395]

Yes

[@JoseRodriguez-gk4dl]

Same as an 2013 acadia??

[@ultimatediyguy395]

I may be actually

[@oOohdaddy]

So replace downstream even if theres no code its giving me bank 1 sensor 1 and that will fix 420 code?

[@ultimatediyguy395]

P0420 is kind’ve a universal code, usually the secondary code will help you look in the right direction. If you have a code for bank 1 sensor 1 change that upstream sensor and clear the codes both should go away
