Default Car dies-- P1518

Hello, I got the P1518 code on my 03, and replaced the TAC Module as I wasn't getting voltage out of one of the pins. Now that I've replaced it it starts just fine and idles no problem until I touch the accelerator then it immediately dies and throws the code again. It allows me to delete the code but again it comes back once I step on the gas. I've checked all of the fuses and had the battery checked...what am I missing? Thank you.

Check the wiring between the TAC and PCM.

Thank you...wiring is good as we checked each pin. It went from not starting at all to starting and idling fine but no acceleration once I installed the new TAC Module. What am I missing here?
