I don't know specifically what the code is. I am assuming that it is the intake temp sensor code. I know this because I just installed a CAI. I used the temp sensor from a mustang and I don't know how to hook the wires up so that the wiring is correct. I was told by a guy on this site that the mustang temp sensor would fit the threads for my intake. It fits perfectly, now I just need to know how to wire it. Now that I know I need to reset the codes - I guess it will just be trial and error. Thanks a lot. By the way - if you (or anyone) know which wires go where - it would be helpful. i have a yellow wire with a red line on it and a blue wire with a yellow line on it (i think). I will check and reply to be sure.
