Santa Fe (DM - 2013+) :: Getting P0442 And P0456 CEL Codes
I hope its just a gas cap issue. I just purchased one online (should arrive next week). I also tried to add Dielectric Grease to the rubber seal on the gas cap to soften it up a bit but to no avail. I hooked up my OBDII code reader to get the codes and it would only read with the car fully turned on and not with just the ACC like other cars without the smart key push button. Is that the right procedure?

Celica :: 2003 - CEL On With Codes P0420 / P0442 / P0446 And P0456
The check engine light on my sons 03 celica is on. Went to autozone and they got the codes for me. They are P0420, P0442, P0446, P0456. I realize that I should probably have an OBD11 reader. What steps do I take to fix this?
View 2 RepliesSonata I45 (YF - 2011+) :: 2013 - Error Codes P0442 And P0456 Came Up
This last May I gave myself a graduation present and got a 2013 Sonata SE. I bought it through my Dad's friend's dealership at a pretty good deal and loved the car for the first few months, then things went South pretty quickly.
I've had more CEL issues with this car than I ever did with my piece of garbage 2000 Grand Cherokee.
The first time the light came on, I brought it to AutoZone who said I needed a new Cannister Close Valve. I then took it to my local Hyundai Dealership (Not my dad's friend's, I recently moved up to Ohio and that dealership was in Alabama) who verified that it was indeed the cannister close valve. They said I didn't need to get it fixed because it actually had nothing to do with the engine, but they gave me the part number should I want to buy it and switch it myself to save a few bucks. I bought the part from them and drove down to visit my family in the summer with the CEL on (who are in Memphis) to have my family's mechanic switch out the part. On my way down I stopped to get gas and, unfortunately for me, the gas hose kept clicking off like the tank was full after a quarter of a gallon, which obviously wasn't right. I brought it to my Memphis Mechanic and had them switch out the part, which they also said would resolve my fueling issue. They said everything was good, but on my short drive home (less than 10 miles from the mechanic) the light came back on. I turned around and my mechanic said he'd look at it. They then told me that I needed to replace a sensor in the EVAP system and that should solve the issue. For the rest of my time in Memphis, and on the drive back up to Ohio, I had no CEL, but I still had the fueling issue, but nowhere near as bad as it used to be. Once I was back in Cincinnati, however, sure enough, that stupid orangish-yellow light appeared back on my dashboard. I took it back to the Hyundai dealership who then wanted to charge me $500 to switch out the charcoal cannister which they were saying was the problem. To my great aggravation, they were unable to tell me that would solve my issue, but that it "should" fix it.
Well, yesterday the CEL popped right back on giving the same codes it's always been giving: P0442 and P0456.
Ford F-150 - 1997-2003 :: CEL Codes P0304 / P0456 / P0171 - Misfire On Cylinder 4
So, my 2003 F150 4.6 that I just put back on the road after a four month break is running like crap. I took it off the road for the winter because it was missing (no codes) and didn't feel like dealing with it then but after running it for a day the CEL comes on. It shows the following:
P0304 - hoping it is a coil pack
P0456 - pending. Gas cap?
P0171 - pending. One bank too lean?
Does the 171 code possibly have to do with the misfire in Cylinder 4? I know it is impossible to tell yet but am hoping there is a potential connection.
Before I parked it in January, it was running a bit rough and stumbled on acceleration but never would show a code. Now all this. Going to change the coil first, tighten the gas cap, check for leaks and see what happens but is there anything common on these trucks that I should also be looking at?
Golf IV R32 :: Cylinder 5 Misfire Codes P0300 And P0305
So i got two codes.... P0300 and P0305. I am thinking its the coilpacks because i changed the spark plugs a few months ago. Cleared it last week and came back today. What else could it be? And is it ok to just change one coil pack or do i have to do all of them? The recall was done in 2007.

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.
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.
Santa FE SM (2001-06) :: 2002 - Misfiring / Codes P0171 And P0300 Came Up
My car is misfiring, codes p0171 and p0300 come up on the code reader. It idles rough and has very little power. I have checked my exhaust , it is not plugged. When I unplug coil #2 while idling there is no change as to the engine performance so I switched the coils around with no difference when coil is unplugged on cylinder #2. I have changed the plugs, there is power to the coil, all plugs are firing and when removed plugs 2 and 3 are wet with fuel indicating I am getting fuel and fire. I have replaced the cam sensor with no change.

Santa Fe (CM - 2007-12) :: Codes P0154 And P0300 - O2 Sensor / Random Misfire
My 07 3.3 SF is throwing P0154 and P0300 codes. Autozone said the P0154 is Bank 2 pre-cat O2 sensor. But exactly which one? The P0300 is random misfire. Could they be related?
View 7 RepliesPassat (B5) :: Flashing Check Engine Light / Codes P0300 And P0301
This morning I started my car and it was idling a little rough. The the Check Engine light began flashing - I immediately turned off the car and consulted this forum and my father the mechanic. After talking with my Dad and telling him that the car had sat for a week, he thought the issue was probably NOT the catalytic converter and thought it was probably related to the car sitting and possibly getting moisture in the gas. I started the car again (the roughness at idle seemed to have gone away) but the check engine light/malfunction indicator light (MIL) did not flash, it did come back on after a few seconds, but as a solid light . And as we've all read, it's OK to drive with a solid MIL.
I took the car over to Autozone and had the codes checked - P0300 (multiple cylinder miss fire) and P0301 (cylinder 1 misfire). I asked them to clear the codes. I has just put in new NGK spark plugs last month, so I didn't think it would be the plugs. I looked at a new coil pack for one of the cylinders. I decided to see if clearing the codes alone would work and drove home. No issues so far, no MIL, no rough idle, no hesitation (fingers crossed).
When I called the stearleship - they recommended I have the car towed, but would not speculate as to what the flashing MIL could be (catalytic converter or bad coil pack(s))...
Passat (B5) :: 2001 - Misfiring - Got Codes P0300 / P0301 / P0302 / P0303?
i have a 01 passat with a v6 in it on 4 motion and im having an issue with soem mis-firing
i pulled the codes. P0300 P0301 P0302 and P0303 which are all saying that there are missfires in cylander 1,2 and 3 and random miss fires.
im also getting a P0340 which is cam sensor A or the right hand bank. problem is i just replaced the cam sensor and when the motor got warm, the code came back. I was told by the previous owner that the car needed a Coolant Temp Sensor....can this be the cause of my mis-fire issue? hear me out.... it only happens when the car is warm so im thinking that the car is warm but the ecu thinks its cold cause its not getting a good signal from the CTS. thus its either advancing the timing as if the motor is cold and cuasing a miss fire or something along those lines. any thoughts?
Saturn - Sl :: 2002 - SES Light Has Been On Constantly - Codes P0172 / P0300 And P0507
Saturn 2002 SL1 5-speed. My SES light has been on constantly for about a year (was intermittent before that) with the codes P0172, P0300 and P0507. The car also idle high (2500+) occasionally at stops. My mechanic said it is likely an intake gasket but would need a full diagnostic to determine and that is not a safety hazard to drive but that I am getting less mph. I can't afford to fix it now but I have an emission test due. Is there a way to turn to light in the mean time?
View 1 RepliesFord F-150 (2004-2008) :: Gode Codes P0172 / P0300 And P0303?
My son just left. We scanned his truck and got these codes.
P0172 Bank 1 rich P0300 random misfires P0303 cylinder 3 misfires.
I used the Torque APP Pro to check these codes. I went to live readings in the Torque APP and saw some readings for Long term and Short term bank 1 Readings.
They are all "greek" to me, and I don't recall what they were, but could get those readings tomorrow.
When I have done searches combining these codes together, I see changing spark plugs. P0172 alone gets me a different train of thought. Mainly CAT issues.
Also, his cranking to start is quite long. (A lot longer than my 6.0L would ever think of cranking) At least nearly 30 seconds of cranking. We are leaning toward first just changing #3 plug.
TrailBlazer :: Running Rough And SES Light On - Codes P0340 And P0300 Misfire Detected
04 trailblazer, 4.2. Running rough and SES light on. Had codes pulled and showed p0340 (CMP sensor circuit malfunction) and p0300 (Multiple engine misfire detected). Replaced the CMP sensor and left negative battery cable unhooked for 20 minutes or so to clear the codes. Upon start up no more SES light and idle was slightly better. Within seconds it SES was back and it is again running poorly. Cruise control is no longer functional as well.

Just got a 98 f150 w/ 5.4 4x4 excab. It idles fine but under light accleration. It starts bucking and missing bad, if I step on it, it down shifts and accelerates fine. If I try to maintain one speed it misses bad. It is not throwing any codes right now. The check engine light did come on for like a minute but went back off before I could have it read. I hooked up a scanner just to see if any codes were stored and got p0300 and p0301. I am going to clean the MAF and check for vacuum leaks. I hear the rear plug and coils can get water in them causing similar problems.
View 8 RepliesFord Super Duty (1999-2016) :: P0300 Code And Various Misfire Codes For Random Cylinders
New plug on right, lower bank 2 plug on left
Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.
Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.
