im new here and im having the exact same problem. the sealer replaced the tps and said it wasnt the fix and i needed the whole throttle body because there is a sensor in it. i called carsons toyota and they they told me i could buy the sensor seperate instead of getting the whole throttle body. 225 compared to 1200 is a crazy price difference. imma try it out and let you know how it goes if it can be done or not.
