Sonata NF (2006-10) :: 2009 - Dashboard Readings Suddenly Went Dead
My 2009 Hyundai Sonata's dashboard readings suddenly went "dead" yesterday that is - the fuel gauge read empty, the speedo wasn't registering nor was the tachometer and the led display couldn't be altered? What might be wrong and whether I can do anything to fix it?

I went to turn my 2005 on today the normal startup screen came on then it went dark for about 5 secs then came on with the normal consumption display but with no readings. Also there is no radio memory and I can't see volume control or radio tuning. Any way to reset the system? Here is what I mean by no readings...

Sonata NF (2006-10) :: Error Codes P0300 And P0276 On LX V6
I recently got a problem with my 2006 LX V6 with 65k mils on it. The car had a few times a rough Idle so I hooked up my OBDII scammer ant got two failure codes:
P0300 miss fire
P0276 problem with Injector #6
Which one is the cylinder #6. I took of the engine cover and checked the connectors to the valves in the front row. I assume cylinder number 6 is in the back row and hard to get access.

Any way clearing this up? (I could find no air leaks)....
Prius (Gen 2) :: Different Readings On Front And Reverse Side Of Dipstick When Checking Oil Level
I know this may seem like a really dumb question, but I was checking the oil on my 2008 prius today and noticed I get different readings on the front and reverse side of the dipstick. One side I have a halfway mark between the 2 marks, flip it over to the backside and I see my oil level is full. So I'm not really sure what the correct reading is.

View 12 RepliesSonata NF (2006-10) :: Code P0300 - Multiple Misfires On 2009 V6 3.3l
I am trying to get a 2009 Sonata NF with a 3.3L V6 to run correctly and i have tried everything that i can find and still get the problem. The car runs very rich with a strong gas smell. The engine runs rough but doesn't stall. The car has has period where it runs fine and then the issue returns but is in more frequent and steady now. The car will run for the first 5 minutes great if it is cold and it also runs good at full throttle and the check engine light went off during hard acceleration which seems consistent with getting too much fuel. I bought a BlueDriver to read the codes and I love the data it provides but I am learning all the features.
For a little history the car has 95,250 miles. At 81157 miles the check engine light came on and an independent shop replaced the downstream O2 sensor and the light has been off for 2 years until coming back on recently. The code showing was a P0300. The shop replaced spark plugs and the manifold gasket with and oil change for $775. The check engine light stayed off for about a month and 550 miles. The car was taken back to the shop and they replaced the rear O2 sensor for $429 . The check engine light was off for a couple of days and then returned with the P0300. It might go a couple of days without a problem and then it would return.
This is when I got the car and started reading all the forums i could for possible causes. I saw the Tech Bulletin on the Variable Valve Timing Oil Control Solenoids so i replaced both valves. The check engine light returned with a P0303 for cylinder 3 misfire so i figured it was a coil so i replaced all the coils. The P0300 code returned. I check fuel pressure after seeing a post about fuel pressure regulators causing the problem but the pressure was correct. I changed the Mass Flow Sensor figuring it was getting too much gas but no improvement. I bought the BlueDriver so I could see more than just the codes. The O2 sensor looked erratic so i changed the front upper O2 sensor.
I found the Tech Bulletin about the O2 sensors fuel trim readings and realized there was an upper sensor on the back manifold and it was reading -18% so i changed it and now I don't know which way to go. I currently have the P0303 code confirmed and P0300 pending. With the live data the items that looked strange at idle were O2 Sensor Bank 1 Sensor 2 steady at 99.2% and Calculated Engine Load a 21.6%. The freeze frame data from when the light came on has all the short fuel trim at 0.0% and long term at -0.8% for both banks. Calculated Engine Load was 45.9% even though I was trying to drive slowly at 29 mph. Mass Air was 21.71 g/s, I had been running 3 minutes from a slightly warm start, Absolute engine load was 44.3%. Anything else to check or data I should look at?
Accent MC (2006-11) :: 2007 - Misfiring Codes P0300 And P0302
My girlfriends 2007 accent as thrown codes p0300 and p0302.
After reading everything I could find, I had coil pack on my list of possible problem items.
The car sat in the driveway yesterday and when she went to start it today, she couldn't get it to.
I got it to start when I got home by giving it some gas while turning the key, but I don't want to drive it anywhere.
The hard start is leading me to believe it's the coil pack.
I was going to start with changing the pcv, spark plugs, and run fuel injector cleaner through it because those are the cheap possibilities...but now may add in a new coil pack.
Accent MC (2006-11) :: 2009 - Code P0300 / CEL Came On And Stayed Over Multiple Startups
Had the CEL come on twice in the last few days. The first time, a restart of the car took it away. The second time, it came on and stayed over multiple start ups.
With Torque Pro and a bluetooth OBDII dongle I read: P0300 - Powertrain, Random/Multiple Cylinder Misfire Detected
From the Internet:
Possible causes
- Faulty spark plug (s)
- Faulty ignition coil (s)
- Clogged or faulty fuel injector (s)
- Intake air leak
- Fuel injectors harness is open or shorted
- Fuel Injectors circuit poor electrical connection
- Ignition coils harness is open or shorted
- Ignition coils circuit poor electrical connection
- Insufficient cylinders compression
- Incorrect fuel pressure
I wish it wasn't so broad... But, as the car is about to hit 60,000 miles, I plan to replace the spark plugs (NGK), engine air filter, cabin air filter. Just had the timing belt done last week. I will check all of the intake couplings for tightness.
For others who use Torque, what other settings could be useful in pinning down this issue for me? I cleared the CEL this morning; it didn't come back yet.
Accent MC (2006-11) :: 2007 GLS - Random / Multiple Misfire And Code P0300
I have a 2007 Hyundai Accent GLS. I just got it from a used car dealership (local) and it runs perfectly. It had a misfire code when i first got it, for all cylinders plus the p0300. It went away when i started the engine again, and didnt come back til a month later (Now). now it wont go away.
I went to advance auto and had them use their OBD2 reader for a trouble code and i got p0300, p0301, p0303, p0304. No other codes present.
I am not feeling anything bad, and from what I am told, a misfire feels like a hard shift. This is of course after getting the plugs and wires changes as well as an oil change. Standard preventative maintenance.
The mechanic used OEM parts got from local parts shop. i think the OEM plugs are the copper ones. I would have preferred iridium as they arent that much more expensive but I don't want to pay for another plug change.
The only symptoms I can think of, is that according to google, I should get around 380 miles to a full tank (11.9 capacity, 32 mpg city). I am only getting 280 from full tank to gas light.
I have also gone through a lot of oil. I checked the dipstick and it was below the low line, so i bought a quart of high mileage oil (same exact brand and type of oil that i gave to the mechanic to use) and it went to just above the full line. This was at around 1500 miles after oil change.
After visiting multiple sites about misfires, i found a few things that caught my attention. One is a site called auto service professional, which talks about the OCV for the MC accent. A lot of sites also recommend gaping the plugs at .035.
Sonata NF (2006-10) :: Random Misfire Code P0300 - Check Engine Light Flashing
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?
Prius (2010-12) :: Check Hybrid System Message - Transaxle Temp Sensor Giving Erratic Readings?
The "Check Hybrid System" message came up on my dashboard. I took it to the dealer, and they said the temperature sensor on the transaxle was giving erratic readings. Unfortunately, they said that the only way to fix it is to replace the entire transaxle. They said I could keep driving it and that it would probably go into disabled mode before it caused any more damage. What I should do? It's a rebuilt 2012 Prius with 25k miles.

My CEL has come on about four times in the last month shortly after replacing the air filter with a pepboys Purolator air filter. I have cleaned the MAF sensor each time using MAF cleaner and the issue along with the CEL go away then come back in about a week.
I don't know if the MAF sensor is bad because each time i clean it, the issue stops. also, upon first glance at the Purolator filter, i thought it looked a little thicker than the stock one but I didn't think twice about it.
Prius (Gen 2) :: P0300 Code And Random Misfire - Car Shaking More Than Usual

I hookup an OBD2 tester on my Prius 2014 Plugin and saw the OBD2 P0300 - Random Misfire. I did a reset and the error still came on. I also tested my friend Prius 2014 Plugin which is factory stock and had the same error. Wonder if that is by design or not. Going to take my ride into the dealer on Friday for my 25K maintenance and have them look into that error. P0300 can be anything. Hopefully doesn't cause more problems down the run..
View 3 RepliesPrius (2001-03) :: Cylinder Misfire P0300 - Error Has Been Occurring Almost Daily
General misfire when the engine light comes on. This error has been occurring almost daily, sometimes it pins it down to cylinder 3. My wife's nephew who is a mechanic says it could be the sensor, but I have only been getting around 30 mpg though the car seems to run alright. I did go ahead and get the plugs replaced, as I was told it could be a bad plug but the error light still comes on as before and the mileage appears no better. What could this be? I am retired on fixed income and dread the very idea of an expensive diagnostic & repair session with a dealer service. Their solution for about everything wrong has been to replace the gas tank (three times already in the life of the car). Last time that did not fix what was going on with the car..

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.
Golf VI R :: MAF Readings To Be Higher Or Lower
What exactly influences MAF readings to be higher or lower? For example I am running similar boost and timing to other Stage 1 cars but my MAF peaks at 238 g/s while others are in the 250's I have heard that you can relate MAF to power but its not exact. I have a Forge Twintake and Stage 1 tune, I have been looking at peoples logs all night and I don't understand why my MAF is reading lower than other Stage 1 and 1+ cars.
