Carrier sensor problems really strange

[Ian21081974]

Hi

keep getting this really strange fault
the main controller keeps alarming and say the inlet and outlet temp sensors have been swapped around but no one has worked on the chiller except me 6 months ago.
I have checked the connections and measured the resistance of the sensors both reading approx 6500k.
Has anyone got the technical menu for this chiller with the sensor values verses temp etc.

its a Carrier 30xa0352------e Ser no 12x614058



Any ideas or help will be helpfull
i was thinking of changing the sensors and maybe motherboard but that could open another can of worms etc.
