Accent LC (2000-05) :: Engine Wouldn't Turn Over For 10 Minutes (CEL Code P2096)
Oct 16, 2012
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.

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.

o my wife was driving our 2005 Accent GLS with about 95k miles yesterday, and it had an issue that it's had three or four times before: the engine would turn over but wouldn't start while it was still warm. In the past when it happened, whoever was driving would wait a few minutes and try again. It always started on the third or fourth try after waiting five to twenty minutes.
Yesterday, however, she was frustrated and so called AAA to have them send a battery truck over and have them take a look at it. The truck came relatively quickly, and they started their diagnostic procedures. The battery was fine (knew that), and he tried all the standard things like cleaning the terminals/harnesses and whacking the starter with a hammer. My wife said that as she and the tech tried to start the car, the turn-over seemed to get shorter and shorter- so when she first tried it would turn for a few seconds, and after a dozen or so attempts it was only turning for a second or less.
Finally, the tech (who apparently seemed to be frustrated at this point) got behind the wheel while my wife was looking under the opened hood and turned the ignition on and held it. The positive battery terminal apparently started smoking and my wife had to yell at him to get him to stop.
After this point, the engine no longer turned over at all. He tried a few more things like cleaning the cables, but no change. He finally said that he would call for a tow truck, and we ended up getting it towed back to our house.
The problem is unchanged since yesterday: there is full power when in ACC mode, but when you turn the ignition all the way to the on position there is nothing but a single loud "click" and a high-pitched whining noise.
I left my ODB bluetooth interface at my office, so I haven't been able to see if there are any codes.

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
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?

Last week I started having problems with my 05 Accent, hatchback, 1.6L engine, automatic transmission. Filled the tank up with gas and the car stalled pulling out of the station and wouldn't start unless I pumped the gas while cranking the engine. Ran and started fine after that and I thought it may have just been an air bubble in the fuel line, since there wasn't a check engine light or any other symptoms after that. Fast forward to this morning and the check engine light comes on during my commute and when I checked it, it gave an EVAP code (P0441). I also stopped to refill the gas and it stalled again as I was leaving the station. Also after I measured the gas mileage I found that I'd lost around 7 mpg (from around 30 to around 23).
I've never heard of EVAP problems causing stalling and loss of gas mileage but I'm not all that familiar with these systems so I don't really know. I'm going to test if it's the gas cap going bad since on the list of things that could cause a P0441 that seems to be the easiest place to start, but other than that where to start looking?

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.

I have a 2003 Accent with the 1.6 DOHC.
It has been fine, but now it is acting up. Car has about 90,000 miles on it. The engine will start fine, hot or cold out. Sometimes the car will idle fine and warm up, sometimes it will idle for a few minutes and then cut off, will not restart until engine cools off. No, it isnt getting hot.
You can start the car, keep your foot on the gas a little to keep it above 1000 rpm or so, and it is fine until it warms up. If you start the car, go a 100 yards and take your foot off the gas it will cut off and not restart until the engine cools.
I replaced the ISB or whatever that thing is called, no change. No check engine lights come on at all. I took the throttle body off and cleaned it with cleaner, seemed to work ok for a day, then the same thing all over again.
What should I check now, very frustrating, but the little thing gets great gas mileage.

My friend's Accent LC 1.3L won't start from time to time. This never happens on cold start, this is always the situation after warm engine stops and needs to be run again after 5-15 minutes. When you try to turn on the car then, starter is rolling the engine but nothing happens (Yellow key light on dashboard is on, so there is no problem with a key code). Then he wait for a few minutes and car starts like it nothing happens. I suspect the crankshaft sensor.

2005 Hyundai Accent stalled on freeway today. It was running fine and suddenly stalled without warning. I tried to restart but the engine doesn't turnover just makes a electrical "weeee" sound. Battery works and lights work. Code reader gave P0340 and P0134 codes.
P0340 Camshaft position sensor "A" circuit malfunction bank 1 single sensor
probable causes:
-Open of short circuit condition
-poor electrical connection
-Faulty CMP sensor
-Engine Mechanical fault
P0134-Heated O2 sensor bank 1 sensor 1 (H02S11) circuit no activity detected
Probable cause:
-Poor electrical connection
-Rich or lean Air/Fuel ratio
-Engine mechanical condition
-Faulty H02S11 (Bank 1 sensor 1)
I'd like to fix it myself; where should I start?

That said my wife bought a 2001 Accent 1.6L Auto while I was overseas and it's been a great car, about 8 days ago it just crapped out. The reverse went out on her so we took it to get the codes read and on the way it went in limp mode, started hard shifting between gears and wouldn't go over 45 she says. Took it in to the stealership today and they said that the trans is shot as well as showing codes for P1527, P0732, and P0734. I know what the two slippage codes are and I can prolly just replace the speed sensors and that will be fixed but I'm not sure about the reverse and P1527.

2003 Hyundai accent GL 5spd has new rings/bearings/lifters and all gaskets (when i got the vehicle it over heated to the point it shut off ) figured it was just a head gasket so replaced it found out rings were shot.. so that's the jist of it. okay so she's timed right spot on but when I go crank up the car it cranks over fast and i have to feather the throttle to get it to startup the IAC makes a weird buzzing sound and wouldn't idle right so i unplugged it and it'll idle fine. When it would finally crank up and idle she drives really well put about 20 miles on her so far just the starting issue pissing me off. I'll post a vid of it trying to start for better description...

I have just recently acquired an 01 Accent with the 1.6L and have had a few problems with it. It has about 112,000 miles on it and at about 109,000 it had the following services performed by the previous owner (reputable shop did the work)
-New battery
-New timing belt kit
-New water pump
-New valve cover gasket
-New plugs
-New belts
-New front pads
-New front rotors
-New rear wheel cylinders
-New front CV axles
-New tires all around
-Alignment
Now since I got it with about 111,000 miles on it, it ran and drove great until I had to put a new alternator on it as well as having to take the center console and automatic shift lever out to repair the wires for the O/D button. Car wouldn't shift into high gear. The problem I am having now is the car will crank but it will not start. Not even a sputter. I drove the car to and from work the day previous and then went out and started it to go to work in the morning and it started fine and ran fine for a minute or two then it just died like I turned the key off. No spitting or sputtering like it was running out of gas just died completely. Checked a few fuses and such and really not sure where to go from here because I don't have a code reader and don't wanna just throw parts at it, I would rather troubleshoot the problem.

When the car is running, the noise is not there OR it is drowned out by the engine, but when you turn the key and run on battery, you hear a buzzing and it sounds like it is coming from the engine, it stays until you turn the engine on or turn the key back off.

My sister-in-law just came home with a P2069 code. I can't seem to understand how to use the search feature here, every time I enter the spam code its invalid even when I am entering it correct...

I would like to know if for the Accent 2003 there is a component that commonly fails and causes a P0108.
Vacuum seems to be ok. At least I can't find any leaks. Pressure at idle is normally at about 30kPa (4.3PSI). It ranges normally between 30 and 50kPa (7.2PSI). When the fault was set it indicated 125kPa (18PSI).
Sometimes the engine runs unstable at idle.
It seems to be an intermittent fault. If I clear the fault it can take about 2 days to reappear.
Otherwise I will have to go through checking the MAP sensor itself, wire harness, idle motor, is that about right?

I have an 05 Accent with about 115,000 miles. It is a GLS automatic.
This morning as I was pulling from a stop light about 30 seconds from my office the car was extremely sluggish. I noticed the CEL light blinking and could hear a knocking sound from the engine. I pulled over and found code P0303, cylinder #3 misfire.
I checked the spark plug cable on the coil side it looks ok. I have not been able to check anything else yet as I am at work.

Last weekend on my way home from work, I heard this small "thump" noise then a rattling noise started. It really sounds like spinning a marble in a plastic bottle.
I got the car checked and we got code 0734 (Gear 4 ratio incorrect). We think there might be a tooth missing on the gear, but the mechanic wasn't entirely sure, as he wasn't a transmission specialist.
Now, I fear this may cost me my first born child, and I might just end up buying a cheap car for the Winter and get rid of this one; the transmission repair costs are ridiculous.
I've been driving the car in the city (30-50 km/h at most), I'm trying to avoid the highway, I'm afraid I'll blow it, who knows.
It has an automatic transmission, with 125,000 km on it, 2003 make.
The noise only happens when the car is moving forward, not when idling/parked, not in reverse. I am very gentle with the car, no highway speeding, no sudden speeding. I did however do an oil change a little over a month ago, and read somewhere on here that if the wrong fluid was used during maintenance that it could cause problems. I will call the shop and ask them about it.

I have a 2000 accent 1.5L I was having issues with the maf. I was running a cold air intake but started having issues. I removed the intake and replaced with stock config. I cleaned the maf and re-installed. The car will run fine, build rpm and return to idle with no problems. The second I put it in gear and try to move the engine will misfire and rattle itself until it quits. I have been driving around for approx a week with the maf disconnected seeing as it seems to run alright, just lacks a bit of power it seems.
