Just checked the codes on Rosstech.
The first one I couldnt find.
The second suggests a regass as a starting point .
If that doesn't work change the sensor

[rhosj]

where are they located

[kite]

I think the pressure sensor is located in the air-conditioning compressor.

....If only I was as smart as this bloody phone

[rhosj]

so the compressor may be scrap?

[kite]

No, If it senses low pressure the compressor won't cut in,that's why your econ light is on .
the switch could be faulty and it can be changed.

G65 is located on the aircon piping according to the etka diagram, to the right of or just behind right side of rad area, which I suspect either your refrigerant is low & needs regassing or sensor swapout, you'd need to drain system 1st before swapping out, also check its actually plugged in.
