P2096 Hyundai Code - Post Catalyst Fuel Trim System Too Lean

I'm noticing that Hyundai has the highest number of views about the p2096 code. Can anyone tell me what it ended up being? Thanku.

How do i fix this problem

What model and year is your Hyundai? besides the engine code, is there any other symptoms?

2011 Hyundai 1
1.8 non turbo

My Elantra is2013 and having same problem

Start by checking for exhaust leaks, if no leaks are present then check the Oxygen (O2) sensors, make sure the sensors are not damage or disconnected. If the sensor are OK, then you have to replace the Catalytic Converter. Before replacing the catalytic convert, you can also try running the engine with high octane gas for a couple of weeks.

Please see comment above. Check for exhaust leaks, then O2 sensor and if all OK replace the Catalytic Converter. Before replacing the catalytic convert, you can also try running the engine with high octane gas for a couple of weeks.

my hyundai is avante 2009 and having same fault

My 2013 Elantra is throwing this code also. Runs fine otherwise. Can you share what your problem and solution was, please?

My problem was solved by hight grade fuel and high way speed..i think my car needs high RPM to cleen injectors..the code was disappear spontanously without anything else..

Thank you for the information!!!

I have 2012 Elantra showing this code. I replaced both O2 sensors a few weeks ago. Code was off for about a week but has come back again. I however have another huge symptom. My Elantra sputters when idling. Has been doing that for about 6 months. Not throwing any other codes though. It never stalls but feels like it wants to. As soon as I start going the sputtering stops. Seems to be worse when the air conditioner is on. ??? ... Odd huh... Would a new catalytic converter address this issue?

It's very possible. Sometimes the catalytic converter gets damage and will also cause engine performance problems. Pieces of the catalytic converter will clog the exhaust air flow causing the engine to sputter and even stall.

Código 2196 es similar al 2096? En el scanner me sale ambos códigos y tengo check engine encendida en todo momento. Saludos y mil gracias.

Cheffer.

No son diferentes. Pero seria mejor que tratara de arreglar el ocdigo P2196.

I have an I20, the light came up. Code P2096, already replaced, sensors, injectors and catalytic converter. Now Hyundai is figuring out what to do because after 500 km the light came up again (probably same code). They have no idea what´s causing the problem and this is a problem that is growing withing this model. I´m using 95 octane gas since day one.

i have the same problem p2096 and I see the firts thing can cause this code is low fuel pressure, im gonna swap the fuel pump then I will come bacl w/ results.

well today after I change the fuel pump I got the same code. I checked the fuel pressure and I found it within parameters so whta's gonna be next? possible the cat..

Hello Ramon
Let me check if I can find more information. What model and year is your vehicle?

Where are the O2 sensors on a 2010 Hyundai Accent, bought my car used and no owners manual.

O2 FUEL TRIM IS TOO LEAN- SONATA 2010 My dears, I am afraid this issue, Hyundai- Sonata 2009/2010- P2096, is popular in most cars. It cost me a lot and the engine light still comes on. IT KEELS ME every time!! Anyway, I had to diagnose the code scientifically and based on previous expertise, and the light still comes on! Basically, there are many to what causes this code to appear, LET'S GO! 1. There must be a leak in the air entering the engine or even the catalyst where the O2 two sensors are placed. 2. Like any other fuel issues, Burgs, Valves and Fuel injectors must be replaced/ checked. 3. During the process, the car will show lateness in starting/ running, DON'T PANIC! Replacing the fuel filter at this point is recommended. 4. If things are cool, the car will resume to the start point and the light will annoyingly show up! Now, I am planning to take a step further against this light, which is either to disconnect the check engine fuse and take the risk depending on performance to diagnose rather than to kill yourself with the light on or take out the catalyst converter ( WHICH I DON'T RECOMMEND). A mechanic, however, suggested to clean/replace the O2 two sensors, but I am not sure I am ready for this step because I have read it somewhere that if the light still comes on just to annoy you but no other performance showed up, it's just then a matter of bad quality of fuel in the tank!! All the best.

I agree with the mechanic; the O2 sensors are by far the most common solution for the P2096 code. I also checked a national database of repairs for the same model and year, and everyone with the same code fixes the problem by replacing the O2 sensor. There are two cases where the problem was the Intake Manifold Gasket. You should check that too.

Hi fellows
Iam facing same problem as you mentioned regarding p2096 code.
My car is accent rb 2012. This code is frequently come although follow all the recommended solution offered by hyundai. But still come.
I think the one who refer such problem to fuel quality is more correct and accurate.
Try to bypass such trouble by modifying pcm program and enjoy.

Saludos, a mi me paso esto que se me encendió el check engine después que use el modo de conducción económico.
Se escaneó y apareció el código P2093.
Ante esto saque los sensores de oxígeno, los limpie, limpie los sensores de árbol de levas estaban sucios.
Limpie el sensor map, después de esto no me ha vuelto a encender la luz.
Mi carro es Hyundai elantra versión Limited año 2013.

Muchas gracias por compartir esta informacion!!

My 2007 Hyundai Elantra has had this issue a lot the past 3 months, the mechanic said it was 02 sensors, catalytic converter, spark plugs, or gas cap. I already had the gas cap replaced, they did the rest of the replacements and it came back on. My car has been in the shop for more than 2x the time I've had it, so today I'm getting my full refund back because the light keeps coming back on a day to a week after I get it. But, do you think it could be a matter of switching to higher octane fuel? The mechanic said it might be a dealership issue where they have to recalibrate the new converter because they don't make the ones that are intended for my year anymore. I don't know if this is true and I don't really want to pay a dealership either. What could the issue be?

Your suggestion isn't a bad idea. I recommend starting with it, at least for a couple of weeks, to see if it yields any noticeable improvements.

When examining a national database of vehicle repairs related to the same diagnostic code for the same vehicle, it becomes evident that one of the most frequent culprits behind this issue is a leaking exhaust pipe situated before the catalytic converter. In over 50% of cases, mechanics have identified a leaking exhaust as the root cause of the problem.
