2010 traverse. Replaced the O2 sensor Bank 2. Cleared out the majority of codes. Now showing 2099 as pending and permanent (post o2 sensor fuel trim above upper limit bank 2 causing lean/fuel was greater). Besides testing for possible leak could this be the mass air flow sensor?
Hello there. With this code set, I found a dirty air filter which I replaced. I deleted the MIL and send the customer to drive the car, a 2016 SUBURBAN. what could I expect?
I drive a 2015 sierra 5.3 and im trying to figure out why the fuel pressure to my high pressure fuel pump drops but the pump in the tanks pressure spike and the truck shuts off
Lean and Rich codes can be hard to diagnose since many things can cause them. Basically, with a Lean code, the air-fuel ratio is off with more air than fuel. It needs to be diagnosed, and components tested. I would start by testing the Bank-2 02 sensors.
I drive a 2015 gmc Sierra 1500 5.3 4whl drive with a po2099 could a leak right at the flex pipe at the 2 connection could that cause to run rich keep doing those video going thank you please respond
The code P2097, “Post Catalyst Fuel Trim System Too Rich Bank 1,” does point to an engine problem. It needs to be diagnosed, but if there is an engine issue, such as a bad injector dumping fuel, it can clog up the CAT.

Great video, very thorough

Greetings, my 2015 chevy traverse lt is fluctuating rpms and i got the same code along with code P0152. Any help i will greatly appreciate.
So i have the codes P1074 and P2099 coming up together... on a 2021 chevy traverse... what might it be? at this point I am at a loss.

Will the p2099 cause the transmission to act up because of an air and fuel mixture being wrong … it on a 2010 Buick enclave cxl thank you
Usually, no, but it may affect the inputs the transmission control module needs to do its calculations.

An exhaust leak can throw the 02 sensors off, but usually, that gives a lean code.
I got this code just replaced all sensors still got the code….silverado 2014 1500
If I got this code and p2097 would u guys say that it's the catalytic converter is bad?
