Problems with 2003 Toyota Tacoma VEHICLE SPEED CONTROL

Loss of accelerator due to bad throttle position sensor/throttle body. when you ease off the accelerator the vehicle will lose all throttle response. then you have to "work" the accelerator in and out until it starts responding again. it happens on take off or anytime you back off on the accelerator. it has cut off on me trying to pull out into traffic and i almost got hit! it has happened on the interstate and i had to try to work my way over with no throttle and try not to get run over! it now happens every time i drive it. toyota doesn't sell a new tps for this vehicle now ( a $40 to $50 part)toyota will be happy to sell me a new throttle body for $1400 and that doesn't include labor. i thought manufacturers were required to provide parts for their vehicles.

I was driving down the highway experience loss of power such as fuel push the throttle down a couple of times it pick back up happened to more times within 10 mi1nutes it did not throw a code been checking it may relate to a throttle body problem been reading about problems with the throttle body do not want this to happen in heavy traffic or pulling out in front of traffic please let me know what or how to take care of this problem

Intermidiot loss of throttle responce, from standing at light or stop sign and from acceleration. hesitation during acceleration until pedel is pressed fully and ossulation while driving at a steady speed on hwy. **no warning codes present**

I was driving my vehicle 2003 toyota tacoma on highway 156 downhill to hollister, ca i was going approx 65 mph and it just jerked back and lost power i was only able to go 40mph no higher , the engine light has not turned on and it seems i am getting no kind of diagnostic error of what could be wrong.

There is a serious hazard with the throttle body where hitting the gas pedal when accelerating will sometimes cause the truck to act as though you took your foot off the pedal - turning left with oncoming traffic almost caused an accident when the truck did not accelerate as you would expect when pressing the gas pedal. i had my mechanic try to diagnose the problem before looking up the symptoms online, and he traced it to the actuator in the electronic throttle body system. researching online after discovering this, it seems there is a major issue with the 2003/2004 trucks with this electronic throttle control system hybrid. this is extremely dangerous and i would have thought this would have been recalled based on the known issues with toyota's throttle control systems in the past. the system does not throw a check engine light code when this happens.

While driving in traffic the throttle stuck at above normal idle and the check engine light came on. i was able to exit the traffic but the idle would not come back to normal curb idle. what my mechanic has told me is that the throttle body assembly has failed and they can only get the part from the dealer. if this had happened on the freeway the outcome could have not been so good. i hope toyota is aware of this problem and going to address the situation. *tr

While driving down the highway, i moved into the left lane to pass another car. when i stepped on the accelerator the nose pitched forward and the engine felt like it was not getting any gas. i was able to press the accelerator nearly all the way to the floor to continue getting power to the engine, but the first 2/3 of the pedal stroke were completely unresponsive. a check engine light came on and it was diagnosed as a throttle body issue. after doing some research, this seems to be a well documented issue on a number of tacoma forums. the cost to replace will be $1400 dollars new or $400 dollars used. i am skeptical to purchase a refurbished part due to the known issue with it. this has happened a total of 6 times in 3.5 years of owning the vehicle and seems to occur in colder weather. typically after pulling over and shutting the car off for 30 seconds, the issue is gone. it will undoubtedly happen again, but you never know when.

The problem that exists is on my 2003 toyota tacoma. it will all of a sudden lose power and have no throttle response, almost as if it was hitting an engine governor. the rpms usually drop anywhere from 200-500 and then comes back up. the power would slowly come back after keeping my foot on the throttle. it consistently does it after accelerating out of an intersection (usually around 25 mph or while cruising (around both 45 mph or 75 mph) on the highway. this drop of power or lack thereof is a huge safety issue, especially when pulling into an intersection or needing quick acceleration to avoid an accident. i have read about many others with the same issues with their late model tacomas. the parts to fix the issue are very costly and the problem seems to be widespread.

Coming to a stop approx 2 mph the engine suddenly revved very loudly and the truck show forward. the brakes did not stop the truck. i swerved to avoid the campsite we were at and hit a tree very hard. the engine however continued to rev loudly and i shifted to park. with the engine still very loud and the wheels spinning i had to shut the engine by removing the key. *tr

Vehicle loses power unexpectedly and is inconsistent. has happened before to me and many, many times by others with the same vehicle. a poorly designed/engineered accelerator pedal position sensor appears to be the issue. toyota has been notified by me multiple times but refuses to acknowledge this serious flaw in their vehicle. most recently, i was nearly rear ended when on the freeway, the vehicle suddenly lost power. fortunately the driver behind me was conscious and was able to make an emergency maneuver to the other lane. someone will die from these problems! this has been well documented by many at http://www.ttora.com/forum/showthread.php?t=13283&highlight=apps+fix i ask that the nthsa please investigate and do something about this. it appears many of us, including myself, have submitted complaints on this issue and nothing has been done. one may argue that this is an 8 year old vehicle so no reason to investigate. this issue has been brought to your's and toyota's attention since 2005. it needs to be investigated! please. *kb

Tl*the contact owns a 2003 toyota tacoma. the contact stated that the hook that held the floor mat in place loosened and caused the floor mat to become stuck under the accelerator and brake pedals. the contact was unable to stop the vehicle while driving 20 mph in the rain. the contact took the vehicle to an authorized dealer who had previously replaced the hook. the dealer did not have any record of the previous repair and stated the the contact would be responsible for the costs of a replacement hook. the floor mat had not been removed. the failure mileage was approximately 120,000. updated 03/03/11 *bf updated 03/07/11

I bought this truck brand new in march 2003 and have had many problems, but nothing you don't expect with vehicles today or anything toyota did not eventually fix, until now. about a year ago while driving down the road at about 45 the truck just lost power and stalled on me. i was almost not able to get it off the road and of course the person behind me almost rear ended me and was highly agitated i had stopped in the middle of traffic and appeared to be driving like a teenager learing to drive a manual shift transmission. when i took it to the dealer i was told it was a bad maf sensor which was replaced along with other items which cost $400. this did not fix it and after much trial and error and research i have found it was the throttle body and one of it's sensors that can't be replaced. when i mentioned this to toyota, they disagreed and said this was impossible. it is funny how many complaints are here and how many more are having this issue who don't even know to file a complaint ...

My toyota tacoma pre runner 2003, throttle position sensor failed on the freeway and i could not accelerate. almost crashed because traffic was really going fast and i had no throttle response . i put the truck in neutral and i put my emergency lights on and rolled to the nearest of ramp. if it wasn't for my years of experience driving, this would not have been so easy. this is very common but the repairs are not. 1500 dollars at the dealership. there are several cases of this occurring if you go to toyota forum you will see this is not a unique situation. this started when i first got the truck in august 2009 but who knows if the previous owner new about the problem. i think she did. i cannot fix it because they only sale the entire throttle body which cost 1200 dollars plus labor 160 dollars. almost 1500 dollars. *jb

I own a 2003 toyota tacoma pick up truck. i've heard about the recall from a friend who was concerned about my truck. the gas pedal is sticky and consistently hollow. the recall just gave me a confirmation why it's like that. please help in adding 2003 on the recall list as well *cn

I was the number 3 vehicle at a red light. first car went through (thinking the light had changed). second car moved into first place. i started to follow and when i realized he had stopped i applied my brakes. i could feel the truck lurch even though i was still pressing the brakes as hard as possible. i slammed into him and caused damage to both vehicles. my foot was not on the gas pedal at all. *tr
