I just purchased an 02 6spd this past weekened and on the way home I had a little trouble and it gave me the 0121 Code? Does anyone have an idea of what that may be? Thanks soo much for the help!

APPS. Mine did it last Friday. Punch the accelerator a dozen times to the floor real hard. Cleared mine up to drive back home from work (2 hours).

Thanks BTW! Did it still give the code after you did that? Also not to be stupid but what is the APPS and where is it?

Accelerator Pedal Position Sensor. I had no idea what this was until i checked here for help. It's located on top of the vp44/injector pump. In short, I understand it to be the electronic equivalent of the throttle cable. If you need a replacement search for user "Timbo01" here on this site. He has a replacement fro $160, as opposed to $400+. Check out APPS threads for help here too.

Thanks soo much! Also how do I clear this code?

Go to auto zone or whomever and borrow their 9135 reader and clear the code. Most of those guys have the 9175 and it won't work on a 02.
