Hyundai - Sonata :: Speedometer And Odometer Quit Working Completely
I have a 2007 Hyundai Sonata SE XM (153K miles). The speedometer and odometer have quit working completely. The speedometer doesn't even move from zero, no bouncing around or anything. The odometer also is not logging miles. My transmission shifts gears just fine and the cruise control works as well. I bought an OBD-II scanner and no codes came up. My first thought was maybe the vehicle speed sensor, but everything I've found on that say the car will shift poorly and the speedometer bounces around.
View 4 RepliesHyundai - Elantra :: 2002 - Rough Idle And Misfire When Hot / Intermittent Hesitation When Accelerating
2002 Hyundai Elantra GT 2.0L 140k miles
Symptoms:
- Intermittent rough idle when hot, slight shutter, surges between 700-800rmp
- Intermittent hesitation when accelerating, cylinder 2 misfire when hot and under load
- Misfires in all gears under load, mostly when under 2000rpm
- Code P0302 when scanned, no other codes
- Symptoms appeared suddenly, not gradually over time
What's been changed:
- Replaced spark plugs, little or no improvement. Old plugs looked worn, but generally in good shape with no significant deposits.
- Cleared code and swapped injectors between cylinders 1 and 2, after test drive P0302 code came back, so it seems that the injectors are good. If the injector were bad I would have expected the misfire to change from cylinder 2 to cylinder 1.
Inspection and Testing:
- Ignition System Testing
- Spark plug wires and primary coil are within specification.
- Secondary coil resistance is high on both packs. Could this be causing a problem with just cylinder 2? Is it worth replacing?
Spark Plug Wires: Specification: 5.6 Kohm/meter +- 20%Cylinder 1: 2.49 Kohm (Longest)Cylinder 2: 2.03 KohmCylinder 3: 1.64 KohmCylinder 4:1.36 Kohm (Shortest)
Primary Coil: Specification : 0.58ohms +- 10%Actual: .6 and .6
Secondary Coil: Specification: 12.2 Kohms +- 15%
Actual (Cold): 16.03K for Cylinder 2-3 pack and 15.94K for Cylinder 1-4 pack
Actual (Hot): 18.54K for Cylinder 2-3 pack and 18.44K for Cylinder 1-4 pack
Air/Fuel System Testing:Fuel system seems to check out. I do not believe the problem is fuel related. There are no obvious cracks or leaks on the intake manifold. A good spray of Carb cleaner all around the manifold causes no change in idle. I might try propane later. No obvious vacuum leaks.
Fuel Injector: Specification: 13.1-14.5 ohms
Actual: Cyl 1: 14.9, Cyl 2: 15.3, Cyl 3: 15.3, Cyl 4: 15.7
Compression Testing:Compression is not great, but within specification. Could the slightly lower compression in Cylinders 2 and 3 indicate a head gasket leak between those cylinders? Could this cause a misfire in Cylinder 2?
Dry Compression: Specification: 145-218psi, <15psi between cylinders
Actual: Cyl 1: 165, Cyl 2: 155, Cyl 3: 155, Cyl 4: 160
Oil/Coolant/Tailpipe:
- Oil looks normal, not brown or milky
- Coolant looks normal and is full, no signs of leaking (coolant has not been changed in a very long time, could a coolant flush work?)
- Exhaust looks and smells normal from tailpipe.
Sticking valve? How would I check this? Bad sensor somewhere? Doesn't a bad sensor usually throw a code?
Hyundai - Sonata :: 1999 - Intermittent Strong Overheating Odor Coming From The Rear Passenger Tire Area
Lately I have noticed an intermittent strong overheating odor coming from the rear passenger tire area of my 1999 Sonata. I was also beginning to notice the car vibrating or riding unevenly. I took it in to Les Schwab to have the brakes checked and was told they were fine with over 50% on all four brakes. I did have the front tires replaced as they were worn and wearing unevenly and was told this is what was more than likely causing the vibrating. That was a couple of weeks ago and I had not noticed any odor coming from the wheel well until yesterday the minute I opened my car door after driving home from work there was the same strong toxic smelling odor coming from the same rear passenger wheel well, but not from anywhere else. I have only noticed this smell after driving home from work and there is a fairly steep hill I go down not too far from my home. Is this a brake issue or something else?
View 5 RepliesHyundai - Sonata :: 2002 - 5th Gear Slips / Transmission Is Going Out?
I have a 2002 Hyundai Sonata V6 with around 257,000 miles on it.
Recently, it has been slipping out of 5th in automatic mode so I have been driving it in manual mode without utilizing the 5th gear. When I'm in 4th, the RPMs are around 2,200 so not that bad going 60 mph.
The first event was when I was accelerating onto the highway on a bridge going 65 mph and all of a sudden, felt a thud in the front end and the "check engine light" came on. I also noticed that the RPMs were registering way too high (way over 3,000k) so basically it sounded like I was going 65 mph in 3rd gear. I had to drive until the end of the bridge, pulled over and shut off the car. Once I started it, no problems driving in 5th gear for the next 45 minutes.
Error codes were P1790 and P1529.
Added a bit more ATF fluid since it seemed low, the "check engine light" turned itself off. I drove at 65 mph for about 45 minutes and felt the front end dip again as the tranny slipped into the 3rd gear. Again, I had to pull over, shut off the engine and turn it back on again.
Because I don't really have the funds for another car at the moment, I have been driving it in 4th gear with a top speed of around 60 mph. The "check engine light" turned off after the last slip, but I have been receiving so many opinions.
I'm pretty sure the transmission is going out....

View 4 RepliesHyundai - Sonata :: 2002 - Trunk Light On Cluster Won't Turn Off?
My trunk light on the cluster gauge will not turn off. I removed the trunk light bulb so it wouldn't drain the battery but over the span of about a month the battery gets low enough not to start, so I'm assuming its keeping something else on in addition to the light. I only drive about 150 miles a month so it doesn't have much time to recharge even if it is a small draw. I disconnected the sensor in the trunk but the light is still on, The odd thing is that if I apply high G's from breaking or accelerating quickly, the light will turn off till I stop accelerating/decelerating (normal driving does not effect it). I'm thinking its probably a short from an aftermarket remote start/security system that was removed. I do not use the factory alarm so I do not care about the trunk sensor being disabled but I cant seem to figure out where to disconnect it from (pulling the fuse did nothing)and I assume I need to find the trunk/hatch pin wire that it is referring to. Or am I going about this all wrong?
View 19 RepliesHyundai - Sonata - Alternators :: 2002 - Battery Lights Comes On While Water Got Into Engine Compartment
I currently own a 2002 Hyundai sonata that was purchased brand new I have mostly kept up with the general maintenance spark plugs, air filters, oil changes, etc. but have been lenient on some of the less noticeable things such as belts background history: my car's alternator has tested fine at multiple places (Walmart and advance auto parts) but when I had tested it, it had only produced around 30 amps when it was built to producing about 90, i assume this is because of a bad diode.
I thought i could just use it until it completely died (despite the fact that it could harm my battery) because I'm still in school and cant afford a lot at the moment, but last night when I was driving home (it was wet out with deep puddles) and I drove through a rather deep puddle with a lot of water getting into the engine compartment. (i have driven this car through many puddles some making a much larger splash, with no problems what so ever.) shortly after I left for work and my batter light was on, I tried different things like turning the AC on high to see if they worked better at high revaluations to find out whether it was the battery or the alternator, as it turns out the fan maintained a constant speed and after work my car started.
I got about 20 feet and it died, my Friend came to charge my car but when he jumped me, the alternator started working again even though not 30 minutes ago it was not, the same thing happened to me today (same puddle same rout) the alternator didn't work going to work and it miraculously did when i went home my alternator is obviously bad and needs to be changed, but is it the alternator causing this problem, or something else?
Accent MC (2006-11) :: 2009 - Speedometer No Longer Works
My speedometer no longer works. A mechanic had the dash out but said I would need a new instrument cluster. However, as I told him, it started failing whenever it rained. Once the car dried out, the speedometer would work again. For awhile anyway but now it's not working at all. I'm thinking there's a sending unit maybe on the transmission that's faulty?
View 6 RepliesCivic - Honda :: 2008 - Digital Speedometer No Longer Read Correctly
I took my son's 2008 Honda Civic Coupe in for an oil change at a local third party shop today. While there, I was persuaded to let the mechanics carry out a fuel injection service. On driving home I noticed that the digital speedometer no longer read correctly. It now reads about 20 mph over. This is particularly noticeable as the vehicle slows down. I saw that the mechanics were having trouble connecting into the fuel system. They were working in an area behind the air filter, and just in front of the instrument cluster. I believe that they may have disturbed a cable or something in that area, which has caused the problem.

I have an 08 Camry that appears to be having the problems associated with the ABS module (intermittent A/C, speedometer not working, etc.).
I've picked up a module/pump from a junkyard. Excuse my ignorance, but the module itself (black portion), does not have any fluid circulating through it? If I'm just swapping that, there is no need to bleed the ABS or perform any programming?

View 2 RepliesFord Excursion :: ABS Light / Speedometer Intermittent But Only Under Engine Load?
Just bought an '03 Excursion v10 with ~150,000 miles on it (Saturday morning). About 3/4 of my 1.5 hr drive home, when I hit my first small mountain, and I put my foot into it, the ABS light came on, and the speedo started bouncing around. Same thing on the second hill/mountain.
Then, after driving it on a couple small trips this weekend, and towing my 2500 lb boat home (20 min drive), it behaved fine (no big hills, etc). However, I decided to hookup my backup camera. During the 60 or so minutes that I had it sitting with dome lights on, etc measuring everything up (also trying to figure out how to fit my tool box in the back).
When I tried to start it when I was finished, it would just crank and crank and crank. Every now and then, it would try to catch, but never would. Left it sit for another 10 minutes and it started just fine. However, once it started, the ABS light came on for a little while, then went out.
At first, I thought "oh no... fuel pump". But then I started thinking about the speedo and the ABS light going whacko on the hills. I'm wondering if it's a low voltage issue? I had the alternator checked out today, and it tested fine at 13.9v. However, I've heard that those tests aren't always accurate.
Hyundai - Elantra :: Intermittent Loss Of Power / Electric
I’m having an issue with my 2004 Hyundai Elantra cutting off, and what to check for next. Basically I have a very intermittent issue where the car seems to lose electrical power for a split second (or possibly total loss of gas – as in, it doesn’t seem to be misfiring, just seems to totally lose all power). If it happens when I first start the car up, the car will start up for a second and then cut off. It also happens randomly when driving at any speed, and when it happens while driving, it just goes out for a split second, and then cuts back on and I can keep driving, so the RPMs Rev up for a second as a result when it kicks back on, but then goes back to normal. But it is completely intermittent, as in, some days it will not do it at all on my 30-min drive to work. I even went a whole week without it happening. But this week it has come back. Some days it will do it 3 times, some days 20 times. Some days its hard to get my car started, because it keeps cutting off when I start it. But so far after I try around 5-10 times it will start up and keep going. Also, this may indicate nothing, but when it goes out for that split second, I can hear a click, or electrical sounding click coming from the dash/instrument panel area. Which is what makes it seem electrical in nature, but I could be wrong, could be a spark/gas thing.
This has been happening it seems no matter what the weather is outside (its been anywhere from the 20s to 60s here in the last few weeks) and it doesn’t seem to matter if the car is warmed up or not. Also, so far the check engine light has not come on, so it makes me think it might not be a sensor, since those will usually trigger the light when they start going bad. Also, when the car is running, it runs perfect. Idles perfect, drives perfect, no misfires, no hesitation, etc. The ONLY problem is it cutting out. Also, it doesn’t seem to matter if the fuel tank is full or half empty. I had read in one place that if the vapor recovery charcoal canister gets full of gas, it will vent liquid fuel instead of vapor, which can result in car cutting off or running rough, but this usually only happens when fuel tank is full. So I suppose it could be this, but I doubt it.The car has 180k miles. Iridium plugs have 60k on them. Wires have 60k on them. Original fuel pump and fuel filter. I wouldn’t think it would be the filter since when it runs it runs perfect. I guess could possibly be the pump having an intermittent issue. Trying to avoid replacing that for now unless I knew it was the problem.
What I’ve done so far:
•I made sure the battery cables are tight and clean at the connection
•I checked as many grounds as I could find, they all seem good
•Alternator puts out a perfect amount of voltage
•I swapped the ECU main relay and fuse with another relay and fuse in the fuse box that were identical
•I swapped the Fuel Pump relay with an identical one in the box
•I replaced the Crankshaft position sensor
•I cleaned the Mass Airflow sensor (though it looked spotless)
•I looked around for any vacuum hoses that were disconnected. Didn’t find any
•I’ve tried resetting the ECU (unplug battery for a while) and I thought that fixed it at first, but then it came back a few days later. And now resetting ECU seems to have no effect.
Some possibilities of what it could be:
•Fuel pump intermittent issue?
•Camshaft position sensor?
•ECU problem?
•Catalytic convertor going bad?
•Some other sensor going bad?
•Possibly the vapor recovery charcoal canister is full of fuel as described above
•ignition coils – but I doubt it since you’d usually get a misfire/engine light when those go bad (from experience)
•Fuel pressure regulator – but I doubt it, based on the symptoms. Seems like I’d have other symptoms.
I’m not convinced of any of these above, and some of them I wouldn’t know how to check (like for a bad ECU). What it might be? Getting nervous driving 75mph on the interstate with someone behind me and the car cutting out. Luckily so far it doesn’t cut completely off when I’m up to speed with someone behind me!
Hyundai - Accent :: 2007 - Intermittent Shift Into High Gear
I have an 07 Hyundai Accent. Occasionally when I start it, it will bang into gear and will not shift into high gear. It is an automatic transmission. If I turn it off and restart a couple of times the problem will disappear. I occasionally get the check engine light with this problem but it goes out the same day. It has also occasionally been going down the highway and will shift out of OD and increase rpms. I can pull over and restart and the problem goes away.

View 9 RepliesHyundai - Elantra :: Intermittent High Pitched Squealing Noise At Highway Speeds
My girlfriend's Elantra (mid 90s model, I think) makes an intermittent noise when on the highway. It sounds to me like it could either be from friction or some sort of wind noise, but I suspect it's the former. It only seems to happen at speeds above 50 or so. When it occurs, it is always the same pitch and loudness -- these don't seem to vary. It's rather loud, to the point where it is pretty unpleasant to drive when this is going on. It has happened both when my foot is on and off the gas pedal. When the noise happens, it can last anywhere from just a second to up to a minute or more. I haven't been able to identify anything obvious that it's correlated with -- wind direction, grade of road, etc. The only thing I do know is that it only seems to happen at highway speeds. We never hear it during city driving. So far one mechanic has confidently misdiagnosed the problem as a bad wheel bearing.

My car developed an "intermittent" accelerator whistling noise coming thru one of the speakers (I think). The harder you accelerate - the louder the whistle. When idling, it sounds like an open air whirring noise. Of course every time I bring it to the shop - it stops and when I hear it it's never convenient to get to the shop!

Hyundai - Santafe :: 2004 - Intermittent Metallic Buzzing Evolved Into Constant Whirring / Grinding Noise
For about a year and a half I have had an "undiagnosable" noise that started as an intermittent metallic buzzing and has evolved into a constant whirring/grinding noise. The tempo of the noise increases when accelerating; occurs at all speeds and at idle. People say they know when I am approaching they can hear my car from about two blocks away.
My regular 20 year mechanic checked transmission, replaced timing belt (at 65K; now have about 74K); all idler pulleys; checked alternator; He thinks is is the AC drive pulley on the compressor; Hyundai dealership did not know what it is; laymen have suggested is is a power steering pump, reservoir issue. Power steering fluid level is fine. Otherwise, the performance of the car is fine.
Engine is 3.5L V6; 2004, about 74+K
