2003 - getting P2121 code

Hello,

My 2003 Tacoma recently started to not accelerate when hitting the gas pedal. Check engine light came on and I got a P2121 code. My mechanic is saying it is the accelerator pedal sensor but we can’t find that part anywhere without buying the whole throttle body. Has anyone else seen this and what did you end up doing?

Thank you!!

Did you ever get this fix? I'm having the same issue. I replaced the throttle position sensor (4pins), then the next day it started to go into limp mode again but this time with p2121 code. Just curious how or if you had fixed it? Thanks,
