Want this question answered?
I posted pictures on the location and replacement of an ambient temp. sensor for a 2001 S40. Google "ambient temperature sensor location/replacement" or go to Matthew's Volvo site and search there.
I'm not sure what you're asking, but if you mean that you are getting an OBD-II diagnostic code of P0128 from your Volvo S40, that code corresponds to a problem with coolant temperature. On a first generation Volvo s40 (99-04), this usually means that the thermostat or electronic coolant temperature sensor are malfuctioning or have failed.
Open the sunroof or put on the air con if no sunroof is fitted.
Next to the thermostat. you will see it when you remove the hose

Where is the radiator cap on a 2001 Volvo s40?
We had the same problem and we were told by the dealer that it was because the ambient temperature sensor was shorting out?!? Since we had that problem fixed we've also had the problem of our passenger-side headlight working intermittently and this morning both headlights wouldn't work.
We had a light alignment problem on our 2007 S40 and they could not adjust due to the design of the head lights... The fix was to replace the left 2007 S40 head light with a 2008 S40 head light....
