Code P 2121
The throttle on my 03 auto acted up this morning coming to work it slowed down by its self and then took off like a rocket I never changed throttle position. I'm assuming its the TPS the CEL came on and now I have this code can someone tell me what the code means??

That is a TPS code , some have had success cleaning , a search for cleaning should find the directions .
With a wiring diagram , to find what color to connect a meter to , move linkage slow & watch , should move with a slow increase in resistance with out any erratic or loss of reading , if odd readings replace or clean .
