JA actually refers to the High Pressure sensor - connected at X46A on your PCB.
You need to check the voltage/pressure relationship of this sensor.
Check your DC voltage between black and white wires and get Daikin UK to send you the chart to check relationship.
If voltage doesn't = pressure chage out sensor...
