I have a 98 sc300 and the car went into limp mode, I made it back to the house but I had to press the accelerator to the floor to do it. I pulled the codes P1121 and P1120. I changed the TPS and the APPS and I still can't drive it. Should I just change out the TB? Any suggestions?

 

did you remove the battery and reset those codes after changing the TPS and APPS ?

if you did , did the codes return ?

 

yes they came back

 

did you get a new APPS ? if used probably bad too ... check and make sure all the wiring to that sensor are not broken

 

I wouldn't buy a used APPS. Buy a new one and it will fix your problem. Same thing happened to my 1998.

 

yes! I bought it new and it's still giving me that probably
