Okay, I got the check engine light along with a wrench light yesterday afternoon. I took it to autozone and it was throwing a p2135 code which I guess is associated with a Throttle position sensor which I hear tends to be a common problem in 2005+ Mustangs...? But my car isn't bogging down like other people say their car does when they have trouble with the T.P.S. It drove home and to work this morning like it always does no problem AT ALL. I live in Arizona and yesterday was over a hundred degrees when I started the car and first got this check engine light. Should I clear the code and see if it comes back, or could there still be a problem? If so, how do I clear the code? Thanks in advance for help.
