Santa FE SM (2001-06) :: 2004 2.7L AWD - P0507 Code And Loss Of Power While Accelerating
Apr 17, 2016
When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?

2004 2.4L Hyundai Santa Fe here, died whilst travelling, lost all power and then wouldn't start. Sounds like its trying to turn over.
The fuel cut off seems to have been activated as it clicked when I pushed it but the car still wont start.
I do not have any engine management lights but when connecting the code reader I got P0320, however the code was stored but not present... and still the car will not start. I cleared the code and the code didn't re appear but the car will still not start.
As the code isn't immediately present does this mean the sensor is at fault or do I have other problems?

I have a problem with my 2004 Santa Fe, 2l diesel. Will try to keep this short!
When driving it suddenly 'heaves' (not sure how else to describe it), then it cuts out. I wait about a minute and then it restarts.
At first there was no 'heave' but there would be a momentary loss of power (I thought it was the clutch). Then it progressed to the 'heave' and then cut out, this happened now and then. Very quickly it started to do it every time I drove it. My neighbor mechanic blew down the fuel line, said the fuel pump in tank sounded ok, seemed to do it more when below quarter of tank.
So I kept tank topped up, it seemed ok, then on one 11 mile journey it did it 3 times, the last time the engine management light came on, crawled it home, after which it would not start at all. The computer said it was either fuel rail or coolant sensor. Neighbor replaced coolant sensor, it started ok. Tried it next day - 6 miles and it heaved and cut out again. This time no light coming on.
I've read about cam sensor, crank shaft sensor, fuel pump at back of engine...

I have a 2004 santa fe with a 2.7 v6. I have had a little misfire issue lately. I had a major power loss with a check engine light on it lasted for just a minute before it settled itself out. Had the code pulled at a local parts store. P0301 so I checked the plugs and they looked worn out. I pulled the upper intake and replaced the plugs and wires plus the upper intake gasket. I cleared the code and that seemed to correct the problem. Two days later, same thing happened. The engine seems to be running fine now. I wiggled the wiring harness to the injector and to the coil, no change in the way it runs. I was thinking it could be an injector or a coil pack.

My wife has had her 2010 3.5 Santa Fe since new. Over the past year it's been having a clunk develop when accelerating, happening a few times from a start until highway speed. The clunks almost feel as if one is driving over bumps - that's what I thought at first. The power doesn't seem to be there anymore either. I have been driving her vehicle the past three years and it was fine when I first started driving it. But the past couple years I first noticed a problem and it seems it is getting progressively worse. My wife now notices it quite a bit too.

2001 Hyundai Elantra GLS ... I don't know what is going on with my car. When I start it, put it in gear and try to pull out, it feels like there is a loss of power. A few seconds later, the power returns . I can push my foot down, and the engine doesn't rev, but then it's like all of a sudden the engine realizes I have my foot down and takes off.

Mine is 2006 with 130k miles. Just replaced fuel filter, air filter, cleaned air flow sensor and cleaned the injectors. The car still feels slow and it seems to eat more fuel than before. The spark plugs and the wires seems to be ok. No warning or error on dash is displayed.
When push the accelerator it takes a while to respond starting from stop position, and when the car is moving and try go faster it feels like lazy so I have remove the feet of the pedal and push it again so it respond quickly.

'01 Silverado with the 4.8, sitting at 160k right now. I'm starting to notice a loss of power in the truck, when pulling out and accelerating it doesn't put you back in the seat like it used to and when going up a hill you have to force a downshift to not lose 15-20mph... it just seems like I'm pulling an invisible trailer back there. The fuel pump is about 1 year old, fuel filter less than 3 months, plugs and wires are about a year and a half old, PCV valve about 6 months old, fuel pressure regulator about a year old..

My engine doesn't run smoothly (like a misfire) when accelerating at hwy speeds, especially when the outside temp is above 20 degrees... the warmer the temps are, the worse it is.
I have a code P0431 - "warm up cat efficiency below threshold (Bank 2)"
Is it an O2 sensor problem, and if so, which one is it and what is the Hyundai p/n for the sensor? Bank 2 is in the front, correct?

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

2004 2.4L 4cylinder manual transmission. I'm trying to resolve this issue I've been having. The main symptom I notice is when I accelerate, the power lags before I feel it going to the motor. Then the power kicks in at some point a few seconds later.
From the codes that have come up I've replaced a mass airflow sensor, 2 coil packs, knock sensor, and now a throttle position sensor. the repair manual I have shows the TPS having slotted mounting holes for adjustment but neither the original part or the new one I ordered had slotted mounting holes only circular holes.

My father owns a 2003 Santa Fe GLS with the 2WD 2.7L V6 engine.
Recently it has been having lots of power loss issues. It vibrates/misses when idling, if you put your foot down on the gas pedal, whether under load or not, it sometimes stalls or just sits there. We took it to Hyundai, and they had no error codes. They charged us $150 to tell us nothing is wrong with it, when clearly something is. The car has become downright dangerous to drive because it cannot make it up hills without stalling/losing power.
The most recent thing we had done to it was the wires/spark plugs changed, which I think was at 65k on the odometer?

2003 Santa Fe - Loss of power while driving on highway. Dropped from 60 to 15 MPH in matter of seconds. Feels like a couple of cylinders (3.5 liter) are not working.

I have a Santa fe 2002 crd 2.0 4x4 and recently had a lot of black smoke and a loss of power when driving, it starts fine but when revving it blows black smoke from exhaust and has no power to pull away, been told its possible turbo problem or fuel problem.

Today I took my AWD 2.7 Santa Fe out. All seemed fine until I made a turn... I noticed I was loosing power and came to a stop, despite pressing the gas pedal fully. The car then started to vibrate extremely hard and all of the dash lights came on. The car stalled completely. I tried to start the car again, but it took a few tries. The car shook severely in park, but when put in drive immediately became much worse and then completely stalled. I did this many times trying to get out of the street. I finally got it to work good enough to get off the road - I did however notice that it would not shift out of 1st gear. It had very high rpms, but refused to shift.
I am guessing this is the crankshaft position sensor? Could this be a MAF problem? I believe I read on this forum about high humidity making Santa Fes go crazy - it has been over 95% today, and raining. I managed to get the car down the road to a shop we trust. They are going to try and read codes later.

Bought my Santa Fe GLS less than 2 months ago and ran fine. Last week, went to store no problems and then went out 5 minutes later, put it in reverse and it stalled. I go to the store, and it lacks MAJOR power.
Now, if I leave it alone for a while it will normally start right up. While idling, everything seems fine. Then my "ghost" takes over the vehicle making it less responsive to the gas pedal. Also, at 3000 rpm, it sounds like its skipping a cylinder. When reading the gauge, it skips between 3000rpm to abut 2800 rpm.

I own a 02 fwd v6 Santa Fe that just lost power on the interstate. It will go about 20 miles an hour and basically does not change gear unless it is in manual mode. I was able to drive it to a local repair shop but they are having trouble figuring out what is wrong with it.
First, they told me the plugs and wires were bad, changed those and still no power. Next, they told me it was the fuel pump, change that and still no power. Next, they said it was the catalytic converters but the said they unhooked them to test the theory and it still had not powered. They said it may need back pressure from the cats so that may not work. They want me to buy them but they are very expensive especially on a guess. Next, they told me if that does not fix it is must be the transmission. Will the cats off keep it from running due to back pressure? Does it sound like a transmission issue or could it be something else?

Initially I used to get cutting out of the engine randomly whilst driving which everyone believes is linked to an ECU issue i believe...I added some reddex fuel cleaner and that seemed to clear the problem up for myself which is a diesel 2.2 ...
However I was beginning to have starting issues where i would need to pump the gas to get the car started...I changed the battery and the glow plugs and yet i was still having issues. I had the air intake and filter looked a diagnostic test run both showing no issues and then one day I was driving and suddenly i got a huge loss of power and black smoke out of the exhaust....Seriously i had no grunt and i was a hazard to cars behind me....!!!! It was weird how first thing in the morning it seemed fine but later in the day i was getting this problem over and over again and eventually the car wouldnt start without a jump from another vehicle..
Any how i took it to various garages but in the end i took it to Rockar Hyundai at Dartford (i cannot recommend enough) but simply all they did was look at the fuel filter and saw that one of the injectors were faulty...After changing this the problem still occurred but again only when the car was warm...They then looked at the pipes leading to the injector that was faulty and then found that there was a crack/split in it and obviously when cold it was sealed but when warm was opening and i believe letting in air.... Anyhow they have changed that and the car feels great and no issues...

I've been having trouble diagnosing a loss of throttle at seemingly random times. Sometimes while driving, especially after driving for more than 20 minutes or so, I will experience a hesitation while on the gas pedal as if I have taken my foot off the gas. It makes it impossible to drive until I pull over and unplug my TPS and then I can drive fine in manual mode. Then the next day I can plug my TPS back in, drive around fine for a bit before the hesitation happens again and then I have to unplug the TPS again and drive in manual mode. It doesn't make sense to me why it takes a bit for this hesitation to begin and why unplugging the TPS and driving in manual mode seems to fix the problem.
I've recently replaced my crankshaft position sensor, idle air control valve, purge control valve solenoid and TPS. When I recently placed the TPS, the hesitation problem and another problem I've been having recently, a high idle in park, seemed to be fixed, but then the hesitation problem popped up again. When I unplug the TPS, the hesitation disappears and I can drive fine but the high idle in park problem is back! I'm suspecting some sort of wiring problem to the TPS. I just went on a 100 mile camping trip in manual mode no problem, but I can't be driving around forever with no TPS.

I just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.
We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.
I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?

On my '03 Santa Fe 2.7, this has happened twice, with 500 or so uneventful miles in between. At highway speed, it just all of a sudden loses power and will only go about 50 mph with accelerator to the floor. When you stop & put in neutral, it only revs to about 3000 rpm, with pedal to the floor -yet idles fine. Then when you shut it down, wait a few minutes & start it back up, it's fine. Is this a fuel problem or what?
