Accent LC (2000-05) :: 2001 GSI - Check Engine Light / Mysterious P0300 Error Code
Jul 19, 2011
Mystery issue with my 2001 Accent GSI (5-speed manual, 1.6 L). I'm getting a P0300 error code and the Check Engine light (the light is like an old friend, I miss it when it's not on). This happened four months ago and I replaced the ignition coil - seemed to fix things - but now the light and the error is back with a vengeance. Car stumbles and runs rough. Changed the plugs and plug wires, but no difference.
BTW, there's a small pin hole in the upper part of the gas tank (just enough to give it a gassy smell when the tank is full) but I don't think the hole would be big enough at this stage to cause the check engine light to come on in the same way it does if you leave the gas cap off or loose.

A few days ago my "Check VSC" warning came on along with the check engine and traction lights being on. I left my car in a parking garage for a week when I was on vacation and the lights came on once I started the car after getting back from my trip.
I have had the "Check VSC" warning before and I fixed it by replacing my gas cap. My gas cap seems fine this time around so I got my codes scanned and the only one that came up was P0300. Having this issue with the 2007 Lexus GS 350? I still feel like it's my gas cap because I bought a cheap replacement last time around.

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.

I got a 2012 Hyundai Accent SE manual 112000 mostly highway miles. For a month now I am getting the MIL on and P2191 code (System too lean at higher load bank1) after erasing the code it appeared again in 3-4 days. I replaced air filter check all valves and vacuum in air flow, changed to premium gas. Pipe that connected to the valve from EVAP system looks not damaged and valve works as intended. While changing spark plugs I noticed that all of them were quite charred. I am thinking to replace both O2 up/down stream sensors. Which not OEM sensors would be the best match for my Accent?

I have a 2003 Elantra GLS. I am intermittently Check Engine light and error code is P0113 - Air Intake sensor issue. I can't locate where the sensor is. I don't see any wire coming of the tubing that connects the air filter to the engine.

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...

while scraping ice off the windshield this morning with the car warming up, it started to choke, engine light came on. Used my OBD reader and found only one code, that being p0740. Cleared the code and all was fine after that, it drives the same way it always has and nothing feels different, revs are the same shifts gears the same. I know it had something to do with the torque converter clutch.

Got this engine code error, how to proceed?
I have a '00 accent, just purchased a few days ago from a private party, when I bought it, I had a mechanic look it over, gave me the OK and said it passed inspection, no mechanical or obvious running problems with the car.
So I was driving around yesterday and the check engine light came on, took it to get the oil changed because I wasn't sure last time it was done, had the oil changed, light stayed on.
So I took it to auto zone to read the error code, was given this information. How to proceed?

2001 1.5L 5-speed Accent
I did a search on this problem and found several people posted the same P0121 code. Strangely many people wrote that replacing TPS did NOT fix it. The code came back in 30 miles or so. Most of them didn't follow up what finally fixed it and only 2 people did by saying they got the code cleared by fixing/replacing:
1. Leak in the intake manifold, bad plug wires, etc.
2. New Head & ECM.
Is there any known fix for the P0121 on Accent 1.5L other than above?

My 2001 accent 4dr will start up no problem when everything is cold, but once I let it idle for about ten to fifteen minutes and if i shut it off, it will start back up but then it stalls and wont start back up, or if i just let it run a little bit longer it also stalls, no problems with fuel pump or relay when it is cold it starts right up, but once it stalls it wont turn back on....the pump is getting power even when its hot so could it be a bad wire or should i test the coils when it gets hot or am i completely looking at the wrong thing?

Check engine light came on. Codes are P0300, P0302, P0304. Plugs were previously changed. Plugs look good. Changed both coils. Light still one. Injectors also previously cleaned. What else should we check for? Valves hanging? Anything else to check for?

I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?

I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.

Had this code show up after the warning light came on and then the light went away after two day, the car seems to be a little sluggish now. I have read that this is a random engine misfire and it could be a bad plug..

2003 1.8t passat wagon. 50k miles... The check engine light came on today. Oil and engine temp are fine. Can most shops plug in and diagnose? Can I get one of those code readers at Advanced Auto parts to read the error code?

What is the meaning or the fault concerning 4608. The above error code was reported on the computer diagnose machine and it referred me to look into the vehicle ownership manual book BUT its rather unfortunate that i could not find that book. So, what to tackle or replace on the engine to enable the check engine lite go off.

I got a P0118 error code on my car. Looked up some things and most people were saying change coolant temperature sensor. I changed it 2 days ago and have not had a chance to clear the CEL. Its still on now, guy at Autozone would not clear it, said it was against company policy.
Will this turn off automatically once problem corrects itself? I went to Autozone and had them rescan the error, this time another code poped up P0444, EVAP(Evaporative Emission System)Evaporative Emission Control System Purge Control Valve Circuit Open. What this can be?

I have a CEL on my 2007 Avalon so I decided to take it to Autozone to get a scan. Error code P0015 was returned. This code has to do with B Camshaft Position, Timing Over Retarded (Bank 1). I've done a little research and I've read that this could possibly from a dirty screen on the Oil Control Valve, the OCV itself, or the Cam Position Sensor. Before replacing parts, what I would like to do first is to check/clean the screen on the OCV. Secondly, I would like to swap the Cam Position Sensor to a different bank and see if the other bank throws an error. If the other bank throws an error, then I know the sensor is bad and needs to be replaced. With this said, I am having trouble locating the OCV and CPS. Where the valve and sensor is located. A diagram would be useful.

I recently bought a 2007 Hyundai Sonata Limited from a private seller. This car has been perfect for the few weeks I've had it. Now, my check engine light came up and the error code "P0660 Intake Manifold Tuning Valve Control Circuit / Open Bank 1" popped up. I'm not really sure what piece to look for, or which connectors to check.

A couple of weeks ago the check engine light came on and when I had the codes checked it showed a problem with the EGR valve. I replaced it and the light went off. A week later the check engine light came back on but when I had the error codes checked there weren't any. After a few days the light went off but earlier today it came back on. There are still no error codes.
I forgot to mention that it's a 2000 Camry, 6-cyl.

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.
