Volvo models this fault code applies to
Applies to the following models:
9 modelsS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The signal from the evaporator temperature sensor is too high, according to the climate control module (CCM). The fault is caused by an open circuit in the signal wire to the module, or by the wire being short-circuited to supply voltage. Air conditioning and temperature control may then work less well.
Possible causes
- Open circuit in the signal wire from the evaporator sensor to the module
- The signal wire is short-circuited to supply voltage
What you can do
- 1Check that the fuses for the climate system are intact
- 2Look for visible damage on the evaporator temperature sensor
- 3Check that the sensor connector and cable are secure and free from corrosion
- 4Check with a multimeter that the sensor signal wire is not open when the connector is disconnected
- 5If the code returns after clearing, have a workshop check the climate control module and replace the sensor if needed
Symptoms you may notice2
- Cabin temperature does not match the setting
- Temperature control or air conditioning does not work
