IS250 2006 DTC code P2120 & P2121
hi, i am getting this two codes not together sometimes shows one and sometimes show the other and the car sometimes has no gas pedal you can floor it and the car barely revs or half of the gas travel is dead i think that is limp mode but that happen driving regular but if i pass a speed bump or hit something on the road it goes limp mode i let off the gas pedal and it comes back on or if not i have to shut the car off then on again. id checked and cleaned everything fuses, relays, TB connector, i cleaned TB also what do i need to change???

I believe those codes point to the accelerator pedal position sensor. The car is throttle-by-wire, and when you step on the gas there are a pair of potentiometers rotated by the pedal that relay that information to the computer.
