Hello, I'm Danny.

Yes, that code is related to the PCM (power-train control module). It might not be receiving a signal from the TCM (transmission control module). I've attached a diagnostic test below to help determine the problem. I've also attached the location of the TCM. Hope this helps and thanks for using 2CarPros.

Hello again.

Your vehicle is not equipped with an external TCM (transmission control module). It is built into the valve body of the transmission. Did you use the diagnose flow chart I've provide in the last post? You will need to have the PCM (power-train control module) tested to find why there is no communication. Hope this helps and thanks again for using 2CarPros.
