Diagnostic code h

[ajsms999]

Hello again,

Can anybody offer a quick fix for diag code h?
I understand that this relates to the air temp circuit. Each time I start the car the screen shows 'frost warning 0 deg'.

This has only just started appearing - since I changed the lcd panel for a new one (used to display the correct outside temp. before).

Is there a quick diy fix?

Thanks
Andrew

Would've thought this would just be coincidence, since lcd display is connected by multi-plugs.
More likely a break in the air temp circuit or faulty sensor.
