Set Multimeter to Resistance 
Remove electrical connector from pressure sensor
Measurement:
Measure the resistance (continuity) across the pressure
sensor harness leads.
Connections are;
CN2 connector pins 39, 40 & 41 to corresponding connection
on pressure sensor connector.
Expected resistance is continuity (zero resistance).
Also visually inspect the harness throughout its entire length and its connectors for any shorts / water ingress.
