The MAP on the diesel should generate a voltage of 5 volts plus or minus a fraction. This is measured with the key on, and on the orange wire to ground.
The other check that is necessary is the continuity between the black/light blue wire to ground. I there is no continuity, have the ECM checked as the MAP is grounded through the ECM.
Check both wires from the harness side of the connector.
