Accelerator Pedal Sensor Problems of Toyota Tundra

Driving at 50 mph, engine losses power like fuel is cut off. Check engine light comes on, throttle pedal has no response until 3/4 down . Very dangerous as I was in traffic and could not drive the truck. I was told it is a problem with the accelerator pedal position sensor. Cleared code & happened again 2 days later, this time as I was coming to a stop. Vehicle stalled & would not restart - same code - p1121.

1. Driving at highway speeds down a freeway (around 60-70 mph) 2. The vehicle suddenly loses all power and just idles, at this point speed reduces by itself down to about 5-10 mph. Pressing the gas pedal does nothing. At this point, I am forced to the shoulder as to avoid other vehicles. 3. Alleviated the problem by changing the accelerator pedal position sensor. This problem should be addressed by Toyota as a possible safety issue.

Today I was cruising along at 50mph and my truck (2002 Toyota Tundra v8) felt as if the fuel cut out. I let off the throttle and got back into it and the response was very slow. Then there was no response at all as I coasted to a stop. The truck idled, but no response to the accelerator. This problem has occurred twice in the last week. Toyota troubleshooting code says it is a faulty accelerator pedal position sensor. They want $500 to fix.

I have a 2000 Toyota Tundra and today, the engine stalled at the first light I stopped at. When I restarted the engine, the truck would not accelerate. It would idle, but there was no response to the gas pedal. Since I was on an incline, I could not go forward so I had to reverse slowly back to a parking lot. When we hooked up the obdii code puller, it came back with a p1121 code. I researched on the internet what this was and found out it has to do with an accelerator pedal position sensor (apps). When I restarted the engine after pulling the code, it appears to be working fine. I do not have a warm and fuzzy feeling about driving the vehicle now. I am glad this occurred at a relatively quiet intersection and not on a busy road or highway or in the middle of nowhere. It seems like this is a pretty common problem on these vehicles and seems to be a potentially dangerous condition you can get yourself into. I am hoping there is a good reason for the sensor in the first place.

While driving at approx. 55mph the accelerator pedal on my 2007 Toyota Tundra suddenly dropped to the floor below my right foot. My truck accelerated to full throttle. The cruise control was not on. The accelerator was not stuck to the floor mat. The truck accelerated at a rapid pace and nearly ran into the rear of the vehicle in front of me on the roadway. I attempted to stop the vehicle by tapping on the brakes, then the accelerator and turning the cruise control button off even though the cruise was already off. Nothing responded and the truck continued to accelerate to a dangerous speed. The accelerator was "floored" and would not move. I had to maneuver around the vehicle in front of me and several that passed going the opposite direction quickly. The truck was gaining speed at an incredibly rapid pace. I continued to brake the truck in an attempt to stop the vehicle and prevent loosing control. I then attempted to down-shift the transmission. This caused the engine to rev uncontrollably. The same happened when shifted into neutral in an attempt to turn the engine off with the key. The rpm's were revving so high that I feared the engine would blow up. I pulled my truck into a boat parking area on the roadside and slammed on the brakes while putting the truck into neutral and turning the engine key to off. The engine, brakes and transmission were all smoking from the stress and high rpm's. I had experienced a similar uncontrollable acceleration about six months prior (Jan. 2008) to this one but was able to recover quickly by hitting the brakes and presumed that it was something wrong with the cruise control. Toyota replaced the accelerator pedal sensor assy but would not say whether this was the cause of the uncontrollable acceleration. They said that it was possibly caused by the aftermarket floor mats that I purchased at the dealership. Unfortunately, the pedal dropped from under my foot without my intervention. Toyota has not responded to my calls.

Faulty apps (accelerator pedal position sensor). Vehicle is designed with a combination of mechanical and drive by wire throttle body. When driving at freeway speeds with steady accelerator pressure, the truck felt as if the fuel cuts off and instantly started to coast. No input from gas pedal when depressed. Truck just idles. This can be extremely dangerous in traffic as there is no input from the accelerator.
