P0237 -- Map Sensor

I have a 2004 6.0 F350, I just replace the crank and cam sensor. When I try to start the truck the truck started after a bit however, I got P0237 error msg using Torque Pro and also with ForScan. The Map sensor on this engine is located over by the AC condenser. I clear the code, and with without starting just KOEO the same code return even replacing the MAP sensor. Cleared the code, unplugged the MAP sensor and the same error code returned. started checked for short to ground and the middle pin of the MAP sensor had ZERO resistance to ground. Unplugged all three connector to the PCM, and still read a short to ground on the middle pin on the MPA connector. My schematic I have show the middle pin of the MAP sensor connector goes to one of the connector on the PCM.. I unable to make a sound judgement on which connector at the PCM and what pin the middle pin of the MAP sensor goes to using my schematic.

anybody else have the short to ground from the MAP sensor?

As I stated on PSN .....

That code should always come up when you unplug the MAP sensor and turn the key on.
