Accelerator Pedal Sensor problems of the 2000 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.

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.
