ambient sensor , if it pluged in to the front bumper then ive given it away because i fitted an aftermarket front bumper.rubish.dose this mean its going to upset something on the car, ie the heater or something?

your air con wont work

thats really funny then because just before i stared to unplug the engine i tested the aircone and like you said it didnt work i didnt know about that then because i had fitted a aftermarket front bumper so i ripped out the air cone oops.

will it affect anything else.?

i wouldnt have thought so, just your little reading of amb temp

I believe the heater will also be affected. The climate control computer will think that the car is permanently driving in the Antarctic (-86 degrees Celcius) and run the defroster and heater accordingly.

ok in that case ill be looking for a Ambient sensor then to put things write cheers that clears that up then.
