I believe Toyota went to a an electronic/electric throttle design in 2002. There is no mechanical connection. A spring on the accelerator pedal returns it to the start position. There are products available at the parts stores for freeing up the throttle body. If you have a car with a mechanical hook up to the throttle body you can free the cable up with products available.
The Toyota Tacoma throttle position sensor is adjustable. There is an adjustment screw on the back of the throttle position sensor.
The throttle position sensor on a 1999 Toyota 4Runner is located by the throttle body. It will be mounted near the throttle cable.
where is the throttle position sensor on a 1998 Toyota 4runner???? can any one help???
I had a similar problem with a Toyota where it was sending the code for Throttle Position Senser I replaced it twice It ended up being the computer that was faulty [[Hope this will help
Should be located on the throttle body
Keeping the throttle body clean is very important for Toyota vehicles. I recommend cleaning it every 15,000 miles.
It is on the side of the throttle body should be on the back side.

In the car
the code P0123 means, Throttle Position Sensor/Switch A Circuit High Input. sounds like a wiring problem to me. I had the same problem with a 99 Toyota tocoma when i replaced it i had to reset the CPU. On a dodge you should be able to disconnect both batteries for 15 mins to 1 hour and it mite reset.
Could be a frozen throttle plate in throttle body - try to free with a screwdriver in throttle throat
take it to the garage
