S80 Heating Output Too Low
Summary of the thread
The initial problem was low heating output in a 2000 Volvo S80, with a solar sensor fault stored in the error memory. A defective cable or plug connection was suspected as a possible cause. A suggestion was made to check the temperature sensor calibration, which led to the discovery of a defective cable. After replacing the cable at a workshop, the heating issue was resolved.

Thanks for the suggestion. Where exactly is the temperature sensor located, and is any special procedure necessary for checking its calibration?

I did not check the sensor calibration myself. I took it to a workshop. They confirmed the sensor fault and replaced a defective cable. I recommend you do the same.

Thank you for the advice. I followed your suggestion and visited a workshop. The cable was indeed defective; the final repair cost was 95€. The heating now works as expected.

I had similar symptoms in my S80. The temperature sensor might be the culprit. Did you try checking the sensor calibration?
