Regarding the MAP codes
We often see that the jumper harnesses provided are not keyed in a way that they can't be plugged in either way which will often invert the signals to 3 wire MAP connector.
We have also seen them pinned wrong.
The best way to know is a Key on Engine off log looking as Barometric pressure as a reference and MAP pressure they should agree within 1 Kpa.
To many times we see 0 MAP during this test, flip the 3 wire connector at teh factory harness and we get 100 Kpa or whatever Baro is.
