Engine light and vsc lights on code p1120 & p1121
Can someone please help me solve this problem. I have read some threads but no answer.
I recently got a 2001 GS300 and the engine light went on with the VSC. The first code I got was P1120 so we replaced the TPS. After replacing the TPS we drove the car around about 5 miles later then Engine light and VSC came back on. Reread for code and P1121 showed. Any possbility someone might know what needs to be replaced? We cleaned the whole throttle body and still gives the engine light and VSC lights.
Second is the AC on driver side is working perfectly but the passenger side just sends out hot air like a heater any possiblity this might be causing the issue. The only thing is the codes showing does not got to do anything about the AC unless Im mistaking. Please help if possible.

Thank you. I did my research but came up on nothing. I wasn't just trying to get a whole new throttle body /used one because it cost a lot. And I just bought this car from a dealership kind of got played.
Second I just pumped air into my tires and the engine check and vsc disappeared anybody had the same outcome? I will have to drive it around agian to see if the lights will show up agian but other than that if I have to change the whole throttle body I'll just do that. Thank you for the response and advice
