Ok, so I'm new to all this Forum stuff so be gentle. I'm getting a P2121 Code on a 2004 ES 330. It went into limp mode and threw the code. everything still works except that it will only idle, no acceleration what so ever. I did some research and see that the code is for the accelerator pedal position sensor. All I'm seeing online is the whole assembly, is there just the sensor available and if so what is the part number? Thanks in advance for your help.
