Engine light - code P0121

300

Asked by Daaani Jan 20, 2017 at 07:45 PM about the 2004 Kia Spectra LS

Question type: Maintenance & Repair

Hello ,
My  check engine light  just came on today.
I went to PepBoys and got a free check for
the Code, but that is as far as free will go.
Is there anybody here willing to help out
with their knowledge and past experience?

The code was P0121, and it said the word  
'throttle' on the display...
What does that mean and what do I need
to check ?

Thank you in advance ,
