Accent LC (2000-05) :: Some Hesitation When Start To Go And While Driving - Codes P1123 And P1128
Nov 25, 2013
I have an 01 accent with a 1.5 engine. Coming up with codes P1123 and p1128. I sprayed manifold with brakekleen and didn't get. Any change in Rpms. Also sprayed maf sensor with maf cleaner. And still have same problems. Some hesitation when I start to go. And while I'm driving. My gas mpg is 25 mpg which seems way low. I just bought car and next day engine light came on with above Codes.

The car run ok maybe a little worse economy and has a shudder very sporadically? What's my next step? new MAF?

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.

I found on internet loads of comment about this error code, but in my case the only bad thing is with fuel consumption - about 9-10 litres (!) for 100 km on motorway. Normaly it should be about 6-8 litres.
The error means: "P1128 is "Long Term Fuel Trim Too Lean". Which means the air/fuel mixture is leaner than the HO2S can compensate for."
Idle is working correctly (i think thats to do with MAF), engine start without any problems and overall car running smooth.
What can cause a bad fuel consumption? Is anything to do with a lambda (O2) sensor or it could be something else?

This is the infamous error code many Accent owners might have experienced it. The code refers to "Too lean intake system". People try to replace all kinds of parts like ECM, MAF, O2 Sensor, TPS, Fuel Pump, Fuel Filter, etc. according to my research. I just bought a 2001 Accent and the P2188 light came on. I wrote an email to Hyundai Corp. Asking what would be the most likely part that will cause the (P2188) check engine light to come on.

02 SE. Had my CEL go on, so went to Autozone to pull my code. Well, ended up being codes:
P1155
Definition - Air/Fuel sensor heater circuit (bank1 sensor2)
Probable Cause:
- Open or short circuit condition
- Poor electrical condition
P1128
Definition - Throttle control motor lock
Probable Cause:
- Open or short circuit condition
- Poor electrical condition
P1150
Definition - Coolant path clog up for coolant heat storage system
Probable Cause:
- Clogged cooling system
- Failed water valve
- Failed CHS tank outlet temp sensor
The car is running fine as best I can tell. Maybe a stutter here and there, but I might be imagining it. Coolant isn't that old, and there are no starting / overheating / electrical issues present.
From what I've gathered, P1155 is O2 sensor and the other two reference the affected area. But....given that they all seem to reference some sort of electrical issue (the last coolant one sounds like it could be electrical), it makes me wonder if I have a short somewhere in my engine harness...maybe heat has corroded the wires somewhere. Sound logical at all?

So I didn't pass the smog check for the new used car that I just purchased 10 days ago. Although my old car (same model), was five years older, I never had this problem. I was told that it is a gross polluter. These are the problem that I have to fix:
OBD Fault Codes - P1128 Manufacturer specific codeP0411 Secondary Air inj Incorrect FlowP0172 System too Rich (Bank 1)P0134 O2 Sensor CKT Inactive (Bank 1 Sensor 1)
How this happens?? 2001 VW ...

I have a 2004 Accent. When driving on the interstate yesterday, I turned the turn signal on and my car died for a moment. After I parked it, it would not start. It did not turn over. Took the battery out to get checked. It was good. Put back in and then the car started. Drove home. The radio and clock would flicker intermittently but made it home. Today it will not start at all. Nothing comes on.

When engine is cold it starts fine, when hot from driving (e.g. the engine's temperature display's needle is in the middle) i cannot start it unless i try 3-4 LONG keys. What can it be? Where should i start?

I have a 2005 Accent Manual, and my check engine light came on a little while ago. So far since then, my car has started to hesitate, and sputter at times. It just doesn't run like it used to. I have owned this car for four years, and it now has 117000 miles on it. I went in to one of the automotive stores in my area, and after telling the gentleman that works there about my car, he sold me some spark plugs, and spark plug wires, because I have never replaced them for as long as I have owned the vehicle. I did and it still sputters and what not. So I went back in and they hooked up their machine to my car and printed off these codes:
P2401
P2419
P2405
P0036

I have a 2005 Hyundai Accent with the 1.6L in-line 4 cylinder engine w/ 160K miles. Over the last few months, I have noticed that when I run the A/C, the car has been at idle for a while, like at a stop light or in park at idle, and I have been driving the car for awhile in the afternoon (summer here), the engine sputters and hesitates on acceleration. The engine makes a pinging, sounds as if it's misfiring and then bolts like lightening, especially when I turn the A/C off. The mpg has declined. I barely get 21 mpg. The car does not have an inline fuel filter, only the "sock" in the tank. I have changed the spark plugs, plugs wires and have run two cans of Sea Foam FI cleaner through the fuel system and the problem still persists.
I am clueless to what could be causing this other than my injectors are still dirty and need a heavy duty cleaning. Could it be an alternator problem because I have noticed the dash lights and headlights get brighter. Could the ignition coil be going out. The car idles fine and the problem disappears when I shut the A/C off and only seems to do this when the weather is hot!

I have a 2002 Hyundai Accent with a 1.5L SOHC and manual transmission, with 207,000 trouble-free miles on it.
I have recently noticed a hesitation under acceleration. It happens most frequently under hard acceleration under lower RPM, if I'm close to lugging the engine. The engine "hiccups," almost like it is missing a cylinder. It will hiccup 2-3 times until engine RPM's increase, then smooths out.
What the cause may be? Last changes: Plugs at 175K; Plug wires @ 160K, Fuel filter @ 100K, Timing belts at 60K, 120K, 182k. K&N air filter cleaned at 50K intervals, last time @ 200K.

I've got a 2000 accent 1.5, and I keep getting a code for a cylinder 3 misfire, when I change the spark plugs, it runs great for about 50 miles or so, then back to square one again. I just changed the coil pack the other day and there doesn't seem to be much of a difference. It has massive hesitation under heavy throttle, and the check engine light begins to blink if it sits and idles for too long. I've scanned it multiple times and it's always been cylinder 3, so it's definitely set on that one... I'm about stumped on what this could be. Also, the previous owner said that after a hot day of driving, the ECU fuse under the hood will blow out, what could cause either one of these things?

The wife's accent started hesitating when turning over to start. Like turn the key, engine will turn 1/4 turn, then nothing for a second or 2 ( without releasing the key) and then crank and start fine.
Checked connections at the battery, cleaned 'em. No CEL on.
I had a ignition cylinder freeze last winter, when my wife dropped her key in the snow and put it in with water on it. Had to heat the cylinder with a small lighter-style blowtorch and put low temp graphite in there.
Did I maybe melt something in there?? Something else??

Recently bought a `01 Accent 5 speed.. First question . How do I tell if its the 1.5 or 1.6 ? That will really point me in a good start. Ha... Ok.. Check engine light is on and I found a paper in the glove box with some of the codes wrong with it.. The one I focused on was telling me the fuel system was to lean . blah blah blah... Dont remember the exact code as I felt that my research was good and I replaced the MAF sensor... Didnt clear the code...
Also it was sputtering quite a bit in all gears mainly at low rpms. I did change the fuel filter , checked plugs and wires etc.. Now I replaced the MAF sensor and it has not solved the problem.. Took it to have it rescanned and have been given codes p1127 and p0136 .. both seem to relate to the Bank 1 sensor 2 O2 sensor. question is I have saw the "upstream" sensor located right below the exhaust manifold but did not see a second sensor?
From what I have gathered sensor 1 does the most work, so I`m curious if these 2 sensors are interchangeable? Could I buy the downstream sensor and if that does not solve my problem , take it out on try it in the upstream sensor? Also do you really feel as though just changing that sensor will "cure" my sputtering issue? the car only has 88k on it and seems to be in good shape otherwise.. I really need this check engine light problem fixed so I can get inspection..

I have a 2000 lc 1.5l ... I just rebuilt the motor machine shop work and all it Will start and run for 3 seconds and then die. If I hold the gas pedal it will run but sound rough and as soon as you let go it dies I have been able to get codes multiple misfires, misfire cylinder 1, misfire cylinder 2, and misfire cylinder 4 I have put brand new plugs (copper core ngk), wires coils, crank sensor, cam sensor, iac, tps, maf and the injectors all have new orings it also has ntk o2 sensors that might have 1000 miles on them...

Car - 2004 Accent auto.- 1.6l - 97K miles
After battling a few months to get my check engine light - fault code P0304 to go off I finally remedied the problem with 3 bottles/fill ups of STP Gas treatment. This was about 1500miles ago. I go to DMV Inspection station and sat for an hour then wait anther 20minutes for the test to end and was given the big fat rejection sticker, she failed because the check engine light came on with fault codes P0304 & P0441.
Now what the heck happened here? Just bad luck and coincidence or did their test set it off? Anyway the P0441 code is new and researched it is the Evaporative Emission Control System Purge Valve. Okay where is it, the HMA manual is not specific? In relation to the intake manifold where is it? Easy fix? And will this solve my P0304 code?

Finally back able to start working on the Ranger and have a few questions.
When I got this thing back from my son it was running rough. I've fixed all the codes it was getting so no luck there now. Not sure how to explain it but, it feels like it is cutting back when driving at a steady speed and it idles rough. Not really like a miss but more like a hesitation when driving.
I've cleaned the MAP and IAC and changed the fuel filter. I also pulled the plugs and they looked good. My son installed new plugs and wires but he used the E3's and not sure how, or if, you're suppose to set the gap. I haven't checked the PCV yet because haven't figured out how exactly you get it out without pulling the intake.
So, where to look next? I'm kind of thinking the cam sensor but think I'll leave that to a shop sense I want the shaft replaced at the same time.
