Double checked the DTC's through the CCM. No ERR. It just doesn't appear. According to the service manuals ERR will only show up if NO communication.... which leads me to this... (unrelated issue) could the CCM be flaking out and just not be looking for the PCM ?
TPS voltage ..... .6 closed and ramps up linearly to 4.5 at WOT.
