Accent MC (2006-11) :: Gas Mileage Went Up - Code P2096
Nov 25, 2014
This is in regards to a 2007 Accent 111k miles, about 3 weeks or so .. I had a p0420 code, and replaced the downstream o2 sensor, and the CEL went off, and gas mileage went up. Now today I got p2096 code. Seems to mirror the p0420 code. So now I am thinking the catalytic converter.
So my questions are:
There are two catalytic converters right? one would be the exhaust manifold and the other would be half way through the exhaust system after the two o2 sensors?
Which should be replaced in regards to p2096?
Could anything else be causing this code?

I have an 05 accent that overheats on short rides, it smells of antifreeze when you pop the hood. There are no visible leaks, and the antifreeze level is good.
Also the check engine light is on and is outputting a P2096 code.
I'm stumped as to what this problem could be, at first I was thinking thermostat or some kind of clog or something like that, now I'm not so sure.

In my quest to get my girlfriends car working, I'm encountering several hurdles, but this one is quickly the most expensive waste if the wrong parts are installed. The car is running rich and rough, lacks power. Here is what I have
Code P2096 - Post Catalust Fuel Trim System Too Lean. The manual indicates: Faulty PCM, Faulty Cat, Faulty rear o2 sensor, or hole in the exhaust line.
When I replaced the o2 sensor, I reset the OBD system and the car ran like a dream for about a week, then same problem, started running rich and rough again, a huge loss of power as well. It doesn't smell like a bad cat, I've replaced to o2 sensor.

Car Throwing This Code ... P2096 Post Fuel Trim Too Lean-B1 ...
View 8 Replies
Our 2005 Hyundai Accent GLS refused to start yesterday. It seemed like the engine was struggling to turn over. It took about 10 minutes and then the engine FINALLY started. CEL came on. We drove about 1 mile and back, and the engine seemed fine. We even turned the car off, and turned it back on with no issues.
We took it into the shop but it's been about a day and they can't replicate the issue.
FYI, the CEL code is "P2096" (Post Catalytic Fuel Trim Bank 1 System Too Lean). This has prompted the garage to look at the fuel pressure system.
Historical Issues:
1. Last year, we found out that the car had minor issues trying to start up. Specifically, it takes an extra second or two for the fuel to be injected into the engine upon start-up.
We would mitigate this by: sticking the key in > turning the key halfway > wait about 2 seconds > then turn the key all the way.
I wonder if this starter ignition or fuel injector is wearing out.
2. About 2 months ago, the car started to struggle when it came to changing gears -- especially on the highway when trying to reach the 4th gear. The car would also randomly jerk regardless if we were decelerating, accelerating or maintaining speed.
Around that same time, the car struggled to go uphill (especially on a very steep highway hill that's near our house). The CEL would flash and we were constantly nervous that the car would simply die and roll backwards.
It seemed like a transmission issue but the garage we took it to replaced the coils, wires, plugs, and vacuumed out excess carbon dioxide buildup. Since doing so, the car was running perfectly.

Got a cel yesterday, got it checked out it read a P2096 fault code. The car runs fine, cleared the code it came back later in the day.

Currently throwing both P0441 and P2096, just prior to this I was also throwing P0442.
Read around on web and decided the simplest thing it could be would be the fuel cap, may as well start there. Owners manual even recommends changing at 90k. Got a replacement from advanced (which is supposed to be built to OEM specs), re-set battery light stayed off, attempted to pass emissions but a few systems were "not ready". Was good for 80ish miles. Light came back on throwing P0441 and P2096. I re-tightened fuel cap and re-set battery, light went off.
Did some maintenance; spark plugs, air filter, oil/filter change and replaced the leaky oil pan. Keep putting on miles hoping to get to the recommended 200 mile mark before stopping by the emissions testing facility, 105 miles after re-set same codes came back. I'm almost positive I replaced a o2 sensor 2ish years ago for emissions. Also there is an obvious exhaust leak which could be a culprit. I seem to remember reading somewhere that a weak battery can cause problems with fuel pressure... not sure if it's true or not but for what it's worth I do know my battery is on it's last leg.
I'd like to avoid unnecessary fixes, it's only my winter car so as long as it's nothing major I'm not going to dump money in it. I'm going to take a guess and say the check engine light is coming on when these systems become ready. Plan is to try this re-set one more time hope for the best and if not replace exhaust or at least repair leak. Not sure on my next step for P0441 though. Vehicle is a 2004 Hyundai accent with 86k on it.

My truck ('10 4x4 w/5.4l, 65k miles) gave a P2096 this past weekend. Cleared it and drove around for a while. Today it threw the same code. No other codes present, just P2096.
I did look under the truck and it seems pretty easy to get to the two sensors. Is it worth swapping them to see if the code changes to the other side?
Truck idles and accelerates just fine. Fuel mileage seems to be down a bit, but the air filter is very dirty and I will be replacing that this week.
I have seen you can check the sensor by heating it and measuring the voltage. Seems easy enough to do, but do you create other problems from that?
I did notice that the connector to the mass air flow sensor is cracked, probably from checking the air filter. I would think if that was the issue it would be showing some MAF code.

I recently got a CEL with a P2096 error code on my 1.8L 2013 Elantra GT auto with 18K miles. This indicates some kind of oxygen sensor discrepancy between the pre- and post-catlyst O2 sensors which could be caused by a bunch of things. I cleared the code and it hasn't returned in a day of driving.
I did a quick internet search and there appears there might be a TSB out for revising the ECU software for this problem, possibly filed under TSB-13-FL-006 or Hyundai bulletin 356015.

I have a 2007 hyundai accent 1.6 l gls, recently got a code p0496 and installed a purge valve and 4 days later got a code p0497 (evap emission sys. Low purge flow). Would it be better for me to take my car to an emission shop where it can be diagnosed since i do not want to take to dealership cause the cost would be very high. I want to diagnose it with some machine that will pinpoint the main problem without me replacing parts just to find out that maybe the part i thought was bad did not need to be replaced.

Recently got broadsided (passenger), got the body fixed up. Now it is Misfiring on idle and only on idle...
Prior to this I had Coil go out on me, got that changed out, changed the spark plugs. It was running great then the accident happened an this Misfire on idle problem.
Took it to the shop, had them check for a code, no code. They suggested that it made be do to carbon buildup from the previous misfiring issue and suggested using STP engine treatment on it.

My check engine light has been on for months and the only code coming up is for the VSS. I got the VSS replaced and the light came back on as soon as I hit 70 on the freeway. Checked the code again and the same one came up. Is this a common issue with 06 Accents? I'm wondering if it might be a wiring or computer issue... My ABS light is also on, would this have anything to do with it?

2009 Accent, 1.6L 154,xxx Cylinder two misfire. Engine was rebuilt due to timing belt. Twice. Second time I did it. Replaced plugs, coil packs, all gaskets, (everything new in the head) did a smoke test, compression test 180 psi across all four, used a noid light for coil packs (good) did it at the injectors 1,3,4 did good, but 2 came on then went off. Check resistance and it shows good, replaced injector anyway and the connecter. Still doesn't work. Checked powers and grounds at the rail, good. Good solid voltage. I hooked up a scan tool and tried to shut injector 2 off, no change in RPM or vibration. Scan tool worked for 1,3,4. Used another PCM, still misfire in two. Even jumped a wire from PCM control and 15A inj fuse for the 12V constant (bypassed the harness) and still doesn't work. Also have knock sensor code, just two codes.

Have VSS code PO501. Have fitted new right vehicle side speed sensor, after reset code clears but quickly returns so still got code. Speedo is working. Have sent ECU for testing - no faults found.
Car is an auto, can the left/drivers side sensor cause this or the transmission sensor cause this?

Twice today my car stalled out while idling. Once at a left turn red light and once in the drive thru. The first time it restarted after about 10 minutes. The second time it restarted after about 2 minutes.
Car is throwing cod P0339 for Crankshaft Position Sensor A Circuit Intermittent.
I did some reading up on this on the forums but didn't do much about it. I just tried wiggling the wiring and all that when idling, didn't notice any roughness or stalling so.... may not be a connector issue.
Anyhow, planning to take it in for diagnosis and repair as it's really not derivable the way it is.
Actually this is the first time ever the car has given me engine trouble of any kind. just passed 90,000 miles. Shucks, streak broken.

I have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.

I have a 2008 Hyundai Accent that is giving me one heck of a headache. I keep getting a code for number 1 cylinder misfire. When you start it up it runs fine for a while then the CEL will flash and it will start running rough. As soon as I shut it off and restart it, it runs fine. I even experimented with it this morning on the way to work. It started running rough doing 60, I put it in neutral, turned the car off and then right back on, put it back in gear. It ran fine the rest of the way to work. I have swapped coil packs, fuel injectors, spark plugs, and have even hang tested another ECM. Still number 1 cylinder misfire.

P0420 bank 1 code popped up while driving. Im thinking this is just an oxygen sensor? Is it ok to drive with this code for a while if i buy an o2 sensor online?

When looking at the engine from the front of the vehicle. what numbers are the cylinders from left to right? To curtail off of that question where do I locate the corresponding ignition coils to these c I have been dealing with intermittent misfires on cylinders 1 and 3 codes P0300, P0301, P0303. I replaced the spark plugs to no avail. Whenever the vehicle shudders the headlights dim and the shuddering is worse when the vehicle is placed in gear, the A/C fan is on, or the vehicle is accelerating. Once I reach a certain speed, usually 35-40 mph, I don't notice until I again slow down. I replaced the spark plugs the day after I had the first issue appear which read code P0301. Prior to installing the spark plugs, I experienced a severe loss of acceleration power, but now only experience the shuddering.

I did a spirited sprint from a stop light and then got this cel. It says it's for the second 02 sensor. I got home, jacked it up and checked it out. Everything looked, sounded, smelled, ran fine. What should I do?
