Causes and Fixes P2097 Code: Post Catalyst Fuel Trim System Too Rich Bank 1 

As a 30-year amateur auto mechanic, I've watched hundreds of car repair videos. This was one of the most to-the-point, clear and complete ones I've seen. Explained pretty much the whole problem and multiple solutions in under 4 minutes. Great video, thanks.

Good job dude! This is how all videos should be. Quick, to the point, and done. Sometimes I swear I want to throw the phone and smash it against the wall when I see these 15 or 20 minute videos with only 2 minutes of useful information in it.

I replaced my 02 sensor with an Oem one brand new. I don’t have a exhaust gasket “ I put my exhaust on in a rush lol “ , I’ll definitely check that out and replace

Tha was helpful... Thank u my friend,God bless u🙏

Hey I'm getting p2097 code in 2017 altima 2.5. I had both upstream and downstream replaced but kept getting several codes. When I went to change spark plugs, I found the upstream wiring connection loose and unable to stay fully clipped in. I rigged it to stay together and plan to fix it asap. All other codes went away after that except p2097.

I just got this code in my malibu and im kinda new to this maintenance thing. The paper printout from the obd says i should reprogram the pcm, should i just try changing the o2 and clearing the code then seeing if it works or should i just go straight into getting to computer reprogramed

Changed both o2s and the cat is new., plugs look fine.. No exhaust leaks to note.. got rid of most codes.. but now p2097 hmm Help!..ok so check out this UPDATE: I cleared the code and drove the car home about 20 miles..the code never came back.. so is it possible that there was still some residual gas in the cat and the new O2 had picked some of that up.. I started the car with the new O2 installed BUT not plugged into the harness cuz I was checking for a Volt reading on my meter.. between .1-1V. then once I got a .1-.2v reading I knew the sensor was working.. I also checked the heater for continuity.. it was ringing loud n clear..so I know the new o2 was working at time of install... the only other thing I can think is that the cat is a cheap universal fitment china type and is not working up to oem spec.. leaving unburned fuel pass through to the downstream O2 to read "too rich" p2097... does this make any sense?. also I thought it could be a sticky injector or bad plug but I checked the plugs, they look mint.. and a bad injector would have given me more codes including misfire.. which I haven't gotten.. yet..help a brotha out, thanks Sir

Brotha, I have a 2016 Silverado. I had a P2097 code. Already replaced o2 sensors. Truck at a idle will start to studder and eventually turn off. No other code comes up. What else could I check? And advise would help.

I’ve changed all 4 and still after some days of driving still pops up p2099 p0430 I got new cats
