Santa Fe (CM - 2007-12) :: 2008 - Accelerator Pedal Stuck Open At Full Throttle
Jul 15, 2011
I have a 2008 Santa Fe Limited and am having a major problem. On 3 different occasions, the accelerator pedal has stuck open at full throttle. At first I dismissed the problem as a fluke or the floormat and pedal getting stuck together.
This week while on vacation with my family in Myrtle Beach, SC, I was pulling onto a 4 lane and had to "punch it" from a dead stop to get up to speed with the other vehicles. When I got up to the desired speed I let off of the accelerator pedal and to my dismay the vehicle kept going. I told my family to hold on and immediately hit the brake and safely pulled into the median while the vehicle was still surging. With my foot on the brake my wife put it in neutral and the engine sounded like it was going to blow up. I checked to see if the floormat and accelerator pedal was stuck together somehow and they were not touching. I do not know if it was me freeing up the pedal with my foot or if the vehicle some how on it's own finally reved back down to normal RPM's.
In essence my family and I were in a runaway vehicle and luckily the braking system was strong enough to safely stop us while at full throttle.
This was a scary experience for my wife and I and a horrifying experience for my children. It was the exact situation Toyota had a couple of years ago with the accelerator sticking on their Prius models.
Is the accelerator system a mechanical one with a throttle cable going to the throttle body or is everything computerized. I do not know if it is a mechanical or computer problem.

I was driving along nicely, then faced with a climb up the hill, I floored it ... the throttle stuck fully and the revs up to 5000 RPM and the governor kicked in, zoom ... hmmm zoom hmmm .. I was lucky cuz I shut off the engine and was able to coast back down to my driveway. No code reader, I decided "how hard can that be" since it happened once before and then worked ok for 6 months ... maybe a linkage, etc
A friend looked at it and tried the old process of elimition ... unplugging the MAss Air Flow connector ... trying it ... then the TPS on the throttle body. He suspected one or both. So I replaced them... happy to get the sucker started without revving uncontrollably. But the pedal was sticky, the idle speed too high and when you press the brake pedal ( and nothing else ) the car stalls, putt putt putt kerplunk. Starts up again tho. but impossible to drive like this. So I gets me a code reader .. follow the directions and this is what I get now
P0441 Evaporative Emission system Incorrect Purge Flow ( this is an easy one even for me ... the engine light came on last time I fueled up - gas cap was not turned enough ) no brainer
P0122 Throttle / Pedal Position Sensor A Circuit Low Input
P0101 MAss or Volume Air Flow Circuit Range / PErformance
P0222 Throttle / Pedal Position Sensor B Circuit Low Input
P2119 Throttle Actuator Control Throttle Body Range / PErformance
P2112 Throttle Actuator Control System Stuck Closed
P2422 Evaporative Emission System Vent Valve Stuck Closed
Puzzling since whatever broke started working again spontaneously last time. I figure, it cannot be all the above at the same time .. perhaps one of the early sensors?

Just talked to a good friend with a 2008 limited, V6. While his wife was driving the throttle went full, then back to idle, then full while her foot was off the pedal. She put it in neutral got to the side of the road and turned it off. She just had towed to the nearest dealer. She said the dealer suspects the Throttle Position Sensor....seems to be a common problem for Hyundai, based on other issues seen on this forum with some losing power, etc. Surprised there isn't more information from Hyundai as the TPS seems to be a weak point.

I have a 2011 Santa Fe, I closed my ashtray the other day and now it won't open!!! It has change in it and I expect a coin has jammed it. The door will push in a little just like it normally would to open it but it won't pop open.

My wife's 07 Santa Fe goes into limp mode while she's on the freeway. Had it towed to a mechanic. They report codes were: 0101, 0102, 1295, 2105, 2106, 2173. They said the sensors in the gas pedal were sending bad signal to throttle which burned out the actuator. So they wanted to replace throttle body and gas pedal sensors. They wanted $895.
Didn't seem right, so towed it to dealer. They said the first mechs were just guessing. Only the throttle body needs replacing. They wanted $960 total.
I bought a used throttle body off another 07 SF with similar vin number to avoid needing the ecm to be reprogrammed. Cost $225.
Couldn't find procedure for replacement in my pdf shop manual. Seems like this should be simple though. Anything special I need to know? Am I on the right track?

2000 Integra with 95k miles in an excellent condition - used pedal jack when parked
I had to make a left turn and ramp up so put it on D3 - I pressed the accelerator and when I felt the speed could be higher (I am not comfortable to drive up the hills) so I must have pressed hard on the accelerator. It then responded
Not sure what was happening, I started breaking and steering - still around 30mph, guessing - it was not a wild drive.
Still not satisfied, I moved to gear 2 and stopped the car. Realized the car is still pulling, turned off the engine and realized the accelerator pedal is stuck.
I pulled it and it has been fine! With the engine off, I pushed the pedal hard and it always bounced back. Not sure that the getting in and out the pedal jack had been interferring with the accel pedal. It also looks like the engineers did a good job that with the stuck accel pedal, I did not end up in a wild drive - I had to brake and move the tranny to 2 but was able stop it - it was a mild up the hill, but unsure if it played a big role.

I have just purchased a 2008 Santa Fe Limited and there is a problem with the steering. At slow speed, particularly in reverse when performing a full-lock turn, the power delivery is jerky and the vehicles jumps a bit.
It feels like either the AWD system is binding or the CV joints are operating beyond their limits. I have ready other posts that this is a known problem - the dealer I bought it from said the same, that it is known and seems to be accepted by Hyundai, there seems to be no recall on this and apparently this doesn't happen in post 20009 models when they face-lifted and supposedly changed the steering lock limits.
I'd like to understand more what is happening, see if there is a solution that I can implement, or alternatively if I have to just accept this, then it would be good to get reassurance that what I am feeling is not going to damage something further down the line.

I own a 2000 F250 7.3 Powerstroke 4x4. The only aftermarket engine modification I have is a Tymar intake. The problem I'm having started about 6 months ago in a very erratic fashion. I would pull up to a traffic signal and as the light changed to green, without warning the truck would have no throttle response. The engine was running fine; there was just no response as I stepped on the accelerator pedal. Usually when I put the transmission in neutral, revved the engine a few times, the throttle would come back on line. This happened 4 or 5 times over the summer and then went away completely until today. Today it came back with a vengeance. At one point I had to shut the engine down completely to restore throttle response. It's a bit unnerving when it happens in the middle of a busy intersection. I was told that it may be the throttle position sensor. Does this sound correct and does it need to be replaced?

I have two Hyundais - 2011 Sonata SE and a 2008 Santa Fe Limited. here is my problem with the Santa Fe.
Brakes: Changed front rotors and pads - rear had the rotors resurfaced and installed new pads. Still get a lot of pulsation when stepping on brake pedal. Is there anything else I should be checking?

My wifes 08 santa fe awd has started to make a subtle clunking that I can feel through the gas pedal. At first I thought it was the AWD system but now it seems to be getting more frequent and noticeable.
I have searched and see that the front stabilizer bars have had issues with this year. Is the thump I am experiencing possible a sign of this?
If so how long would that be covered under warranty. The 3/36 has just expired on us.

About, one month ago my car shut off while driving(pretty scary at the time). I pulled of the road and attempted to start it again. Everything looked good there, but as I was making my way home from work it started to act funny. It would not acknowledge me depressing the accelerator. When I got home, I ate supper, then went to have a look.
The car would turn on, but not acknowledge me pressing the accelerator at all, It did however go up to 30 mph at a snails pace as if it was coasting down a hill. I plugged in my code reader, and it read that the Throttle Body Valve was stuck open. I took it off and tore into to it a bit. I noticed the gears inside the TB itself were corroded and the butterfly valve was locked up.
I replaced the part, and tried to turn my car on with the new TB. All the dash lights are in working order, however upon turning the ignition to crank the engine, the whole car system shuts down. No lights no nothing, besides the car door open sound. The car will remain like this regardless of the key position until I have reset the batter(take off the terminals and put them back on) to which the process repeats itself.
The code reader says no codes are stored because I obviously reset the battery. So now am at a standstill.I believe the old TB froze up, because I had to run in through 3 ft standing water during a storm, and then deployed shortly after(I'm in the service) for a few months while letting the car sit.

We have a 98 Honda Civic that recently developed a problem with the throttle getting stuck open. With the engine off, the throttle will return to the idle position. However, with the engine is running, when the accelerator pedal is pressed, the engine revs increase, but then do not decrease when the pedal is let off. The same thing happens when the throttle is manually opened (not using the cable) with the engine running. The valve for the air intake doe not seem particularly dirty. I cleaned the spring assembly which I initially thought was the problem. The car is sitting the the driveway with both of us moderately terrified of driving it?

My 2008 Elite has a door that won't open. The rear door on the driver's side.
It is an Australian Elite model. I can hear the click when the remote is pressed. How can I get the door open to remove the intyerior trim?

Have a 99 Ranger XLT, 4 cyl, manual transmission with 191K miles. Was running good as ever last night but went to start it this morning and throttle's stuck open, causing truck to move forward when in 1st gear. Even with clutch in, near impossible to get vehicle in or out of gear. Managed to get it into reverse, but truck was having none of it. What is the cause or causes of my trouble? Or how much the repairs might cost? I'm on the road so no chance of doing this myself.

I got in a work truck yesterday, sat down, put my seat belt on and started the truck. Just as I did that another employee drove by and waved, all I could do was nod back at him because my hand was still starting the truck. This took my attention away for a split second, then as I put the truck in gear, my foot still on the brake, I noticed that the tachometer was pegged and the engine was racing. I instinctively pushed harder on the brake pedal, then looked down to be sure that I was pushing on the brake pedal and I was. Right then then rear of the truck started shaking violently and as fast as I could I turned the key off and put it back in park. This all happened in about 1 second, maybe 2.
The shaking was caused by the sheared off driveshaft. And it was sheared off because the center section of the rear differential had broken the spot welds that hold it and place and rotated on the axel housings. It is now pointing upward towards the bed of the truck. Have a drive by wire truck run the engine at wide open throttle with no input from the pedal? 2010 F150 4.6L...

On my daily commute in stop-and-go traffic, on a bridge, headed downhill, suddenly neither the accelerator nor the brake pedal would engage in my 2008 Elantra. Cars in front of me had sped up, then ground to a halt, and I was coasting downhill toward them, at a pace too fast for the handbrake to stop me. I couldn't downshift either (the car has automatic transmission, but shifting to low lets the engine slow you down). With nothing else to try, I shut off the ignition and then turned it on and, amazingly, all was back to normal. The dealer didn't find any trouble codes in the computer so they say the car must be OK to drive. But I don't feel safe driving the car. This might have happened and what I can do to fix it?

I've just started to get what I can describe as a jet engine winding noise up when I accelerate when in drive, whatever gear and whatever speed. I'm thinking it's the auto gearbox, 92k miles (I've not checked oil), the noise doesn't happen when not in gear. It lags like a turbo noise, but if it was the turbo, it would happen always? There's no loss of performance and I can drive it normally with no noise, just if I accelerate harder whilst underway.

My R is vibrating in second gear near full or full throttle around 2,000 Rpm. It feels like a high frequency vibration. It seems to be only happening in that scenario. It's when the turbo spools up and there is a large rush of exhaust gas produced very quickly. My guess is that my apr downpipe paired to the stock cat back is the culprit. It didn't happen when I first put the downpipe on, but after the next track day it started. I don't know if there is anything to burn in inside the apr downpipe but it got louder too. Could it be back pressure from the stock cat back? It's very strange and I wondered if it is stage 2+ but running the stock cat back has felt this? I checked to see if the drive shaft was rubbing on anything and for any other visual indicators of rubbing around the downpipe and I see nothing. Perhaps it's the stock muffler. I'm just not sure.

My check engine light came on the other day and the code stated the the "throttle position is open" so after researching and everyone telling me that i need to change the sensor. I did everything after was fine running better but today only after 3 days replacing it i get the same problems. car has no get up and go hardly can push to 20 mph and when in idle i press the break it starts to bog down and almost want to shut off! and can be really loud...

2001 2.4 L AWD Manual Transmission.
Live data readings from vehicle continuously indicates "open loop- driving" for the Fuel System Status (Fuel System 1) . During idle and on open high way driving as 120 km for 10 minutes. I use an ELM327 diagnostic device with ScanMaster-EL 2.2 software.
After establishing this initially I disconnected the battery to do a complete ECU reset. I do not get error codes.
O2 Sensor1 Bank1 constantly reported as 1.275 V and sensor 2 as 0.02 V. I believe however the constant readings are as as a result of being in open loop.
No error codes reported.
The software report OBD1 ability on the diagnostic link.
During driving I got the following readings:
Fuel System 1: open loop-driving
Fuel System 2: not supported.
Calculated load: 6.27 to 83.14, avg 40.6
Fuel trims: 0
RPM: 1008 to 3988, avg 2407
Speed (km/h): 0 to 122, avg 77.66.
Timing Advance #1 degrees: 7 to 44 degrees, avg 22.42
Intake Air Temp (degrees C). 19 to 24
Air Flow Rate - (g/s): 3.18 to 69.27, avg 25.46
The software reports that the O2 Sensor bank 2 is not supported. I am not certain whether I should trust the software. In South Africa cats are not mandatory, hence is it possible explanation.
2) Is it possible to send a command on OBD to force closed loop?
