P2096 Code, any help?

Hey All,

Recently had this code CEL on my 14 Sorento. It's the v6 with about 93k on it. Seems to be the "right" bank 1 O2 sensor is the most likely cause.. I see their is 2 and of course it's not the easy to get to ones on the front of the motor.. Anyone had to do this job? Does it require removing the upper intake? How bad is that?.. There is such limited information for DIY folks on these cars.. Any help would be great..

Well, there might be nothing wrong with the sensor. It simply means the sensor's feedback to the computer made the computer think the air/fuel mixture is too lean. Too much air, not enough fuel. That could just mean you have an air leak around the intake manifold, a leak in your exhaust, a clogged fuel filter, or a clogged injector.

With the engine idling, spray some starting fluid or flammable brake cleaner around the intake manifold. If the idle jumps/changes, you have an air leak (which would mean you would need to replace the intake manifold gasket. Not extremely difficult, but it's pushing the limits of novice-level DIY.

If you don't find an air leak, I would pour a can of SeaFoam or Gumout in the fuel tank. That might clean the injectors enough to where the code doesn't come back after you clear it (assuming that's what caused the error code in the first place).

If there's no improvement, you can try replacing the fuel filter. That's definitely more involved because you have to remove the back seat to get at the fuel pump. At 93k, it's possible that it's clogged. I think the owners manual says to check it around 45k if I remember correctly.

But practically, chasing down the source of codes like this can become a real rabbit hole. Might be best just to take it to a local shop.. especially if you don't already have a lot of tools. But I would at least do the air leak test and pour in the fuel cleaner. No real risk in doing those and the materials needed are cheap.

Okay, yeah I had read some of these other possibilities I'll give your recommendations a try . I agree diagnosing is the hard part. I'm pretty mechanicaly inclined an have tackled some pretty involved jobs with a decent write up in hand. I have a fair amount of tools but diagnosing I suck at as at the end of the day I'm just a YouTube mechanic.. I appreciate the help Thanks!

Just some additional info... P2096 is the post cat (downstream of cat) . I have not ever looked for the sensor, so It may require you getting under the car to see if its accessible. You will need an O2 sensor socket, or can rent one free at a local parts store. Since your not getting any upstream (pre cat) codes it could be just a worn out sensor, or maybe a plugged cat. Cost for a downstream sensor is about $50.00 (USD). Part number difference between bank 1 and 2 downstream sensors is probably length of the cable. Shop cost to analyze and replace would be in the $100.00-$200.00 range.

Yeah I have the special socket, both the top and bottom are pretty buried on the back side of the motor, I was under it the other day and I am not even sure if I can wiggle a wrench or ratchet in there from the bottom enough to get a decent turn on it.. Its up in all the sub frame mess.. From the top id have to remove the intake manifold probably to have enough access.. its going to a PITA unless I missed something.. The darn code went out for now its been a few days.. Im sure it will be back.. This car is just full of surprises..

Anything about that service manual reference look funny to you.

It's a generic 2.4 liter vehicle 8 year old manual that Kia left out there on the internet for free. They update the 2011-2019 date range, but content looks the same.
AKA: a Hayes Manual. You actually will have to pay for something accurate and applicable to your vehicle.

It's generally accurate up to my 2016. After that, I can't verify. In some of the sections, it will show the 3.3L.. in others, it won't. But Kia's manual/TSB subscription prices are pretty insane, so ksmanual is good enough to guide you through most maintenance/repair jobs. I would only get short-lived Kia subscription if I really really needed it for wiring or something.

The OP car is a 6 cyl, The service manual is for a 4 cyl. Hardly the same intake manifold or cyl head. Not even close to looking like a 6 cyl. SURGE TANK removal.
