Volvo models this fault code applies to
This fault code has different meanings depending on model, model year or engine. Select the meaning that applies to your car.
Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The signal from the passenger-side temperature control is faulty. This is probably caused by a defective potentiometer, or by a short to supply voltage or ground in it. The control module then works from a midpoint value, so the temperature on the right side may be wrong.
Possible causes
- Defective potentiometer
- Potentiometer shorted to live voltage or ground
What you can do
- 1Turn the right temperature control between max and min and check that the temperature on the right side of the cabin changes
- 2If the fault returns, have a workshop check the control and its connector
- 3If the fault is permanent the climate control module must be replaced, since the potentiometer cannot be replaced separately. Have a workshop do this
- 4If you have a diagnostic tool, follow the control value in live data while you turn it between its end positions
Symptoms you may notice2
- The cabin temperature does not match the value you have set
- Buttons and control knobs on the centre console (climate) do not work, work reduced or work incorrectly
What the fault can affect1
- The control module uses a value equal to half of the temperature control's maximum travel
General guidance for car owners. Diagnosis on the car can point to a different cause.
