I need help, last night my truck lost all acceleration when driving and when I checked the codes it threw the 0121 code. Now I know that it is the throttle positioning sensor, but I was just wondering how I am supposed to go about fixing that, before I go out and buy a whole new TPS is there anything else I can try? It still drives but I am nervous that it will lose acceleration again.

thanks for any help
