I replaced the purge valve a while back, i just replaced the ccv and gas cap. The light is still on. Could a bad Ftps cause both those codes? Do i possibly have cracked/bad lines?
View 1 RepliesJust turned 80k and recently noticed a bit rougher at idle. Other than that all has been fine. Plugs, etc. all original. Engine and VSC Light. Autozone ran the scan which turned up the above stated codes. They are defined as Evaporative emission control system pressure. He said it could be a loose gas cap. Checked it and its tight as a drum.
View 3 RepliesCheck light came on and I had the code read at AutoZone. There were 3 codes but I'm pretty sure 2 are old (the check light previously came on a couple of months ago and I had it checked, then went off on its own). My car seems to be driving fine.
The new one is P0455. Large EVAP leak. I'm hoping it is just my gas cap.
The other 2 (older) codes are P0456 (small leak) and P0113 (IAT error).
I've been having P0441 & P0455 codes showing up on my 2007 Corolla CE. My code reader tells me the areas that need checked. But, I can't find the vacuum switching valve on it so that I can check it for problems. Somebody said it's under the hood, but I can't seem to locate it.
Is is possible that it's mounted on the vapor canister (which I have located above the rear axle)?
I have the 2011 Santa Fe V6 and it has the P0447 & P0455 codes popping up on my reader. I checked the pins to make sure that there is voltage getting to the solenoid, (about 11volts at the 2 pins) and it seems good. No fuel lines broken, or cap messed up, etc.
View 6 RepliesEngine runs very erratically and I got ignition failure codes on all cylinders plus mixture too lean code. 2 years ago I changed the gadget that sticks right into the middle of the engine and regulates the mixture and the issue disappeared. bought the part from rockauto. should I change sparks and ignition cables or order the same part again? Never changed the ignition cables and sparks.
View 12 RepliesIts been cold here in CT for the past three days. It's been in the negatives... My engine light came on last night with a p2414 so I ran it, looks like front o2 sensor (could be a couple of things), so I cleared it and waited. Today it came back with p2195 and p2414. A different code for the same sensor. But my question is this. Before I replace the o2 sensor. Is there anything common for this car that would throw this code?
View 21 RepliesMy 2005 Elantra GlS Hatch's CEL light has been coming on and off. Mostly on now, because of course it is 1 month away from needing emissions checked. I am getting 2 codes------ P2626 and P0139 . The first one is the upper O2 sensor and the second was is for the lower O2 sensor.
The problem is that I replaced the upper sensor a year ago because of the same CEL code. The lower sensor was replaced in 2009 ish under warranty. Why these O2 sensors are going bad so quick?
One of my guesses is that my wife only drives the car about 6 miles round trip to work and the car never reaches proper temperature. She never drives on the hwy but lately I've been driving it to work on the hwy and she drives our new 2013 Elantra. The 2005 only has 51,000 miles.
Connected my obd2 to my car and found 3 fault codes 1 which repeated itself twice.. the codes are P0453 that repeated itself a couple times and the 3rd one is P0133.. I looked them up and see that one can be either bad grounding and also a bad oxygen sensor? and then the other mentions something about fuel and says something about fuel pressure sensor?
View 3 RepliesI just joined the forum mainly to care of my dads 2001 Hyundai Santa Fe but also I got a check engine light on my way home from work last night.
From last night I saw that oil was all over the timing belt. Today I inspected it with a Coworker and his OBD II reader.
Error Code was P0455, EVAP - Evaporative Emission Control System Leak Detected (gross leak).
Now the oil leak is stronger since the oil spills is on hood (inside hood). I will make a picture tonight when I get home.
I personal think it's leaking from a tube/ valve on top of the timing belt (picture will show more tonight). Thinking of cleaning the timing belt area, then drive a little around or leave it in idle to spot where the leak is from.
Common issue? I googled around but since P0455 is a common issue (on my 9-2x as well) I couldn't find anything about this I am also limited from my search since I am currently at my work PC incl. strong firewall.
I will see if google let me find a picture...
I would like to find out why my car is misfiring before throwing parts at it. I have a basic level of mechanics and have checked a few things before posting here, which may or may not have ruled out some possibilities.
The problem: I have been consistently getting P0301 and P0304 but only happens sometimes, while other times there is no check engine light. I first checked the ignition coil, right side of it, that controls cylinders 1 and 4. Did resistance test, measured for voltage, and checked the wires for continuity to the connector, with everything coming out good. I know a few must have had issues with the cheap pigtail connector like me so I went and changed that but still got the misfire codes. I then put in an older known to be good working coil but no change.
After that, I removed spark plugs 1 and 4 and put them where 2 and 3 go but still got the same codes P0301 and P0304.
A friend who is a mechanic for Nissan checked the spark and wires, saying they were fine. He then checked the injectors and noticed that injector 1 didn't increase in ticking sound when RPM increased. He said I should replace injectors 1 and 4 to see if that changes anything or switch injectors 1 and 4 with 2 and 3 to see if the codes at least change. I removed them all, got two of them from junkyard just in case, made my own tool where I pumped straight fuel injector cleaner through each of them with pumped air, and put the two from junkyard on cylinders 1 and 4. I still got the same codes so then I switched injectors 1 and 4 with 2 and 3, which didn't change the codes.
I was told by another local mechanic shop that it's definitely the coil but I knew it wasn't.
Other info: I am not sure it would matter when dealing with a misfire but I borrowed a code scanner and saw that the Long Term Fuel Trim was -7%. I researched that and it means that the car is running rich and the computer is being told that it needs to run lean. I am not sure that this would make only two of the cylinders misfire and the freeze data shows that same negative LTFT for when the P0301 happened. I also know that there is an air leak at the gasket where the front cat connects to the flex pipe/rear cat. I have also gotten a rear downstream 02 sensor code once within the past month but it hasn't come back.
Would the LTFT being lean have anything to do with the misfires? Would the gasket between the two cats cause the 02 sensor to get a faulty reading? If so, would the downstream 02 sensor be able to adjust to a lean fuel mix? What else should I check?
I've replace the input and output transmission speed sensors on my 01 GLS. check engine light is on again for 2 P0501 codes. There is no abs speed sensor on the left side but there is on the right side which doesn't look like it is seated correctly. The transmission is still shifting kinda funny sometimes. Should I have abs speed sensors on both sides? And what else should I do to fix the random erratic shifting?
View 3 RepliesMy '02 Elantra would have a hard time starting up in the winter right after I filled the gas to full. Usually I would have to give it some gas to startup. After that, it didn't have problems starting up until I filled it again. This was only in the winter.
About a month and a half ago, it became really slow to accelerate. Since the O2 sensor light had been on constantly for a long time I never bothered to check it. Soon the car became really slow to accelerate and would lunge forward in spurts. The error codes I got were P0133 and the O2 sensor. I replaced the spark plugs and the spark plug wires, and this seemed to do the trick. The check engine light went away, the car sped up nice and quick. Also at that time, I put in some fuel injector cleaner.
The a couple weeks ago, P0133 and P0420 came back. It seems like the car is using up more gas than it should. There is a very minimal sluggish response when I push the gas. I have a spare ignition coil, but trying to find what it could be more specifically before I swap out more parts willy nilly.
I have a 2005 Elantra with about 160,000 miles on it and my CEL light has been coming on and off. I took it to Autozone and had them scan it, and the codes for P2237 and P0030, which are codes for oxygen sensors.
P2237- heated oxygen sensor pumping current control circuit-bank 1 sensor 1
P0030- heated oxygen sensor sensor- bank 1 sensor 1 heater control circuit fault
Which sensor is this, and can I clean it or should I just replace it?
Check engine light came on while driving home from work. The car seems to be running fine but I got the following codes p2195, p0420, p2096. I have a 2006 elantra with 184000 miles. Should I just replace the upstream oxygen sensor or is there a more likely problem? I rather not spend the money if this combination of codes is likely has a different cause but replacing the sensor appears to be the quickest and easiest solution.
View 5 RepliesTrying to troubleshoot my 2001 Elantra (173k). I'm having intermittent trouble codes being set and I'm wondering if they may be related:
P0302
P0303
P0446
The cylinder 2 and 3 misfires are relatively recent. Plugs and wires are visually ok (and not that old). I swapped plugs 1 and 4 with 2 and 3 to see if the plugs are bad. It took 3-4 days, but the P0303 set again (and it's very intermittent - car will noticeably lose power for a few seconds, code set, then run fine for several days). I also sprayed carb cleaner on the intake manifold gasket with no change in engine idle, so the gasket appears to be intact.
I had read in a forum somewhere that the misfires could be related to a vacuum leak, which could also be setting the P0446 code. I removed the charcoal canister and inspected the lines - visually ok.
I bench-tested the canister control valve and it did operate, though I noticed some charcoal blocking the valve so it would not close all the way when energized. I used compressed air to blow the debris out of the valve and it appears to close properly now.
I went to hmaservice.com and noticed there are no instructions for the P0446 DTC. I've been using a Haynes manual instead. For quite some time now when refueling, the fuel nozzle shuts off every few seconds (I have to slowly put the fuel in to avoid).
Some questions:
- Can these codes be related?
- Based on my symptoms, should I replace the canister control valve? What about the charcoal canister and the charcoal air filter - should those be replaced as well?
- What else should I check?
Have an 01 elantra as a second car and it's great. Just recently tho the check engine light came on and I've got a few codes that make sense since there has been some odd issues with it in the past month or so.
02 sensor CKT bank 1 sensor 2 (slow response)
shift solenoid D malfunction
shift solenoid C malfunction
shift solenoid B malfunction
Trans range circuit malfunction (PRNDL input)
So I know the 02 sensor needs to be replaced, that's fine. I'm more concerned about the rest of the codes because when cruising around 40mph the car tries to shift to 4th gear or something like that, it will bog down because the rpm is too low (maybe its overdrive, not sure).
That's a minor issue but has been there since we got the car over the summer, the bigger issue is the last couple of days, i've noticed that when driving the car around the city, slow down - turning - and then accelerating the engine/trans will buck harshly a few good times before it smoothens out, my guess is the gear change didn't go well.
How to diagnose the following codes: U0D00, P0711, P2300.
U0D00 - What this means.
P0711 - Transmission Fluid Temperature Sensor "A" Circuit Range/Performance. How would I go about fixing this?
P2300 - Ignition Coil "A" Primary Control Circuit Low
I have the following codes:
P0705
P1529
It looks like P1529 is caused by P0705. P0705 is the neutral range sensor. I purchased the sensor and replaced it. It is aligned correctly and I am still having the same CEL and codes.
What the car doing: The car jerks into reverse and drive. The dash does not indicate what gear I am in (PRNDL).
When it drives, acceleration is very slow. I believe the car is "stuck" in third gear. I've heard of fail safe mode?
What I did: This problem started when I changed my stereo. I did three bad things which may have caused this problem.
One, I had to put the car in "L" to get the dash off. I left it in "L" for a while then I tried starting the engine while it was still in "L".
Two, when I reinstalled the center console I swapped the wiring for the hazard lights and the rear windshield wiper (GT)
Three, I wired the dash illumination positive and negative together.
The cluster's backlight does not come on anymore and these codes came up. I checked all fuses and they are good. Where to look for a possible shorted wire that can be causing this?
I have no problems pumping gas in, but the entire car cabin smells very strongly of gas after filling up. It seems to come from the area of the charcoal canister. No dripping of gas, no puddles... Did a smoke test, no leaks showed up anywhere (according to the mechanic). I do not want to start throwing parts at this to fix it - where should I start, and in what order should I throw parts? 2003 elantra GT sedan, 70k ....
View 1 RepliesI have a 2001 Elantra GLS, 160,000 miles. These two codes come up on ny diagnostic tool.

Main catalyst efficiency below threshold (bank 1)
No symptoms at all
P1529
Customer snapshot request
Symptoms
Car will shift hard into third gear and stay there without shifting at all regardless of speed. Shutting the car off and restarting will sometimes fix, but only temporary. When car runs normal, it runs fine and shifts good. At speeds around 40 it seems to kick back and forth between 3rd and overdrive as if it can't decide where to be. Tried replacing speed sensor, but new sensor did not fix problem.
