I have a 2005 Volvo S40 2.4L and the outside temperature gauge is about 20 degrees low at all times. Some of the little information I could find revealed that this could be a problem with the sensor itself or it could be related to a technical service bulletin that would run 5-6 hours of labor at a shop. But I couldn't find any information specifically related to a 2005 S40. <p>Where is the sensor located on this car? Is it the drivers side mirror? Could I just order a new sensor and replace it? I would just take it to a Volvo dealer for an estimate on the issue but the nearest dealer is about 250 miles away.

Re: incorrect ambient temperature reading (five)

Sensor is underneath the drivers side mirror. You could replace it yourself but i must warn you its not plug and play, it requires re-pinning the mirror connector. <p>You would have to have the car scanned for the door harness issue. If multiple PDM and DDM codes are stored odds are the TNN must be carried out.

Does the temperature reading being off indicate other issues with the door harness or could it simply be isolated to the temperature sensor? If it is the door harness issue, is that an estimated 5-6 hours of labor?

Re: (five)

Yes however if you are consistantly a certain temp off then sounds like you may have a sensor failure. If it was the door harness connectors then the most common complaint is sporatic or crazy temps and then back to normal and crazy again and so on. This is due to corrosion in the terminals causing things to short out or interfere with other signals in the connector.
