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…

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…

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…

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…

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…

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…

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…

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…

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.…

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

After driving for approximately 2 hours, on three separate occasions, the vehicle would intermittently lose significant power. It felt as though i had taken my foot off the throttle. After my own investigation, i learned that toyota has a history of this problem, particularly with their 2003/2004 model tacoma's. Evidently, their accelerator pedal position sensor (part of their throttle by wire design) fails. This…

Throttle body sensor went bad, and in turn, caused the truck to lose about 90% of its throttle. It happened to me several times in high traffic, causing me to lose almost all power ,and cars behind me to slam on there brakes.*ak

At any time, my 2003 toyota double cab 4x4 tacoma pickup truck will lose all power as if i have removed my foot from the accelerator pedal when in fact i have not. This will cause my truck to drastically decrease speed until i pump the gas pedal until it decides to work again and pick up speed again. I have done much research on this issue and have found that the cause is a faulty "drive by wire" throttle body which…

Vehicle has a history of problems that the dealer cannot determine the causes. Vehicle does not properly shift into gear, has a rough idle, and a knocking noise in the engine. Dealer could not duplicate the problems because they were intermittent. *ak
