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
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?
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
@@ultimatediyguy395 on my way to change it now i tried over weekend i couldnt get it loose so tight above that cat plus it was hot when i was trying while laying on my back so that was a bust this time im raising it in the air take 2 😂🎬

More than likely yes, you may need new need a new car. Some people like to try catalytic converter cleaner as a last resort
Are they all the same part number? I am having a terrible time on google determining the correct replacement parts
The downstream sensors for bank 1 & bank 2 are the same
Isn’t there more than 1 O2 sensors?
Yes on this vehicle there’s 4 of them
@@ultimatediyguy395 I know where 2 are gotta find 2 more now lol
Did this fix the issue?
Yes
Same as an 2013 acadia??
I may be actually
So replace downstream even if theres no code its giving me bank 1 sensor 1 and that will fix 420 code?
