Air con diags code 25

[DAMQIK GTS-T]

I have just put my air con in diags and get error code 25 (with the 5 flashing) the sun sensor,

I have pulled it out of the top of the dash to find out it's only a photo diode, can anyone tell me what mvolts it should be outputting on a voltmetre?

I get about 580 mv under a 50 watt light dose this sound right?

as the diode dose not seem to be faulty what else could be causing this code?

Thanks

DAMQIK, this is a bit of a simple answer, but you did run the diags in sunlight, right?

LOL - yeah, Duncan is right. Make sure the sunload sensor is in full sun light when you test it.
