I just replaced transmission with ATS Stage 4 and it has the Co-Pilot built in with included harnesses. One has the adapter to plug into MAP Sensor. When I plug into sensor I get the P0238 code but when I remove it and plug back into factory it goes away. Anyone have any idea why this is or is there a way to tune it to accommodate this?
